Every test. Plain English.

Your blood pH is within the normal range, indicating your body's acid-base regulatory systems (lungs and kidneys) are maintaining proper pH balance.

Your pCO2 is within the normal range, indicating your lungs are effectively eliminating CO2 and maintaining proper ventilation.

Your pO2 is within the normal range, indicating your lungs are effectively transferring oxygen from the air into your bloodstream.

Your bicarbonate level is normal, indicating your kidneys are maintaining adequate buffering capacity to maintain blood pH balance.

Your base excess is within the normal range, indicating no significant metabolic acid or base excess in your blood. This is a good indicator of metabolic stability.

Your O2 saturation is within the normal range, indicating your blood is well-oxygenated and your lungs are efficiently transferring oxygen.

Your lactate is within the normal range, indicating your tissues are getting enough oxygen and not producing excess lactic acid through anaerobic metabolism.

A normal IGF-1 suggests your pituitary–liver axis is producing enough growth-hormone signal to match typical 24-hour activity for your age bracket. IGF-1 peaks in adolescence, settles through your 20s, and gently declines thereafter; a reading in the normal range is what most healthy adults show. On its own this value is neither a flag nor a diagnosis — it's a quiet check in the routine-physiology column.

A normal active B6 level means the many enzymes that depend on it — across energy metabolism, neurotransmitter production, and blood cell formation — have enough cofactor to function. You don't need to be in the top of the range to cover requirements; the middle of the reference interval is adequate for most adults. This is not a marker that benefits from being "optimized" above normal; balance is what the enzymes want.

A normal AMH for reproductive-age women suggests ovarian reserve sits around where we'd expect for your age. It's one of several inputs a reproductive hormone specialist uses to estimate fertility runway — the others being antral follicle count on ultrasound, FSH, and age itself. AMH does not predict egg quality; it's a quantity signal. A normal reading is quietly reassuring but not a more likely.

An Omega-3 Index between 4% and 8% is the zone where most people who eat fish occasionally but not regularly land. Cardiovascular-outcome associations improve roughly linearly as the index climbs toward 8%, so while 6% isn't "bad," there's still headroom for improvement. People in this middle zone typically eat one fatty-fish meal per week, take a modest omega-3 supplement inconsistently, or rely partly on plant sources.

A normal value suggests the adrenal and gonadal androgen pathways are operating where we'd expect for your age and sex. It's one of the background checks used when investigating androgen-related issues (acne, extra body hair, irregular cycles, PCOS workup); a normal reading helps narrow where to look next but rarely changes the plan on its own.

A normal ionized calcium means your biologically active calcium is where it should be. Parathyroid signaling, vitamin D handling, and the kidney's calcium management are cooperating as expected. Since ionized calcium is the form that actually matters for nerve and muscle function, a normal reading is the most reassuring calcium number you can have.

Bone marrow is producing red cells at a typical rate. No current indication of marrow stress or failure.

No ongoing significant hemolysis is detected by this marker.

The intrinsic clotting pathway is functioning within expected bounds.

Methylmalonic acid (MMA) is a byproduct of a specific B12-dependent enzyme reaction. When B12 activity is sufficient, MMA gets efficiently converted to succinyl-CoA and never accumulates in the blood. That's why MMA is considered a more reliable marker of cellular B12 status than a simple serum B12 level — serum B12 tells you how much vitamin is in the blood; MMA tells you whether the vitamin is actually doing its job. A normal MMA is strong evidence that you have enough B12 for your enzymes, regardless of what the serum B12 reading shows.

Lactate is a by-product of anaerobic metabolism and clears rapidly. A resting value in range suggests normal tissue oxygenation and mitochondrial function.

A normal anion gap means the difference between your measured cations (sodium) and measured anions (chloride + bicarbonate) falls where we expect. In plain terms: nothing unusual is accumulating in your bloodstream that we haven't accounted for. This is a useful background check whenever someone looks at a chemistry panel, but it rarely drives decisions on its own when it's normal.

CK is an enzyme released from muscle cells whenever they are stressed or damaged — strenuous exercise, an intramuscular injection, a muscle bruise, or more rarely cardiac injury. A value inside the reference range at rest means no significant muscle injury was detected at the time of the blood draw. Keep in mind that normal ranges run higher in men (more total muscle) and in people of African ancestry; a well-muscled athlete at rest can still read in the high end of "normal" without any pathology.

LDH is released into the blood whenever cells are stressed or damaged — essentially any tissue in the body can contribute, from red blood cells to muscle to liver to lungs. A value within the normal range means no significant tissue injury is currently being flagged. Because LDH is so non-specific, a normal reading here helps rule out a few things (significant hemolysis, major muscle breakdown, active hepatitis) but doesn't tell us much beyond "nothing major is releasing enzyme right now."

Your total IgE is in the normal range. This is a reassuring result for systemic allergic disease. Atopic conditions (hay fever, eczema, asthma) are less likely to be IgE-mediated at this level.

Your food-specific IgE is in the normal range. No IgE-mediated allergy to this food is detected.

Your eosinophil count is in the normal range. This is a reassuring finding for allergic and parasitic disease surveillance.

Your ECP is in the normal range, consistent with controlled or absent allergic inflammation.

Your plasma histamine is in the normal range, consistent with no active allergic reaction or histamine dysregulation at the time of testing.

Your ANA titer is in the normal range, with no clinically significant antinuclear antibodies detected. This is a reassuring result for most autoimmune conditions.

Your anti-dsDNA is in the normal range. This is a reassuring result for lupus surveillance.

Your anti-Sm is negative, which is the normal result. Anti-Sm is highly specific for SLE when positive but is only present in a minority of SLE patients.

Your anti-SSA/SSB is negative, which is the normal finding. This is a reassuring result for Sjogren's syndrome and neonatal lupus surveillance.

Your anti-Scl-70 is negative. This is the normal and reassuring result for scleroderma surveillance.

Your anti-centromere is negative. This is the normal finding for CREST and limited scleroderma surveillance.

Your rheumatoid factor is negative and in the normal range. This is a reassuring finding, though RA cannot be completely excluded based on RF alone.

Your anti-CCP is negative. This is the normal and reassuring result for rheumatoid arthritis surveillance.

Your C3 is within the normal reference range. This is a reassuring result indicating no excessive complement consumption and no evidence of significant autoimmune-mediated complement activation.

Your C4 is within the normal reference range. This is a reassuring result indicating no significant immune complex-mediated complement consumption.

Your anti-TPO is in the normal range. This is the reassuring finding for Hashimoto's thyroiditis surveillance.

Your anti-TG is in the normal range. This is a reassuring finding for autoimmune thyroid disease surveillance.

AST is an enzyme found in the liver, muscles, and other tissues. Birds have naturally higher AST levels than mammals. Normal levels indicate healthy liver and muscle tissue.

ALT is a liver enzyme. In birds, ALT is less specific for liver disease than in mammals, as birds have lower ALT activity in their liver cells. Normal levels are reassuring.

CK is an enzyme found primarily in skeletal and cardiac muscle. Normal levels indicate no significant muscle damage. Birds naturally have higher CK than mammals due to their active metabolism.

LDH is an enzyme found in many body tissues. Normal levels suggest no widespread tissue damage. Birds have higher baseline LDH than mammals.

Bile acids are a sensitive liver function test in birds. They measure how well the liver produces bile and the portal circulation delivers it to the intestines. Normal levels indicate good liver function.

Uric acid is the main nitrogenous waste product in birds (analogous to urea in mammals). It is produced by protein metabolism and excreted by the kidneys. Normal levels indicate good kidney function.

BUN represents a smaller fraction of nitrogen excretion in birds compared to mammals (uric acid is the primary end product). Normal levels are reassuring for kidney function.

Birds have naturally high blood glucose levels compared to mammals, typically 200-400 mg/dL. This is normal for their high metabolic rate and is not a sign of diabetes as it would be in humans or dogs.

Calcium is critical for bone health, eggshell formation, nerve function, and blood clotting. Normal levels indicate adequate dietary calcium and proper parathyroid function.

Phosphorus works with calcium for bone health and energy metabolism. Normal levels indicate balanced mineral homeostasis.

Sodium is the main electrolyte that regulates fluid balance and nerve function. Normal levels indicate proper hydration and kidney regulation.

Potassium is essential for nerve conduction, muscle contraction, and heart function. Normal levels indicate good electrolyte balance.

White blood cells defend your bird against infections. Birds have naturally higher and more variable WBC counts than mammals. Normal levels indicate a healthy immune system.

Hematocrit measures the proportion of red blood cells in the blood. Normal levels indicate good oxygen-carrying capacity and no significant anemia or dehydration.

Hemoglobin carries oxygen in red blood cells. Normal levels mean your bird's tissues are receiving adequate oxygen.

No antibodies against Chlamydophila psittaci were detected. This means your bird has not been exposed to this bacterium. Chlamydiosis is a zoonotic disease that can spread from birds to humans, causing flu-like illness.

No circovirus DNA was detected. PBFD is a serious viral disease affecting parrots, cockatoos, and other psittacine birds that causes feather loss, beak deformities, and immunosuppression.

No antibodies against Aspergillus fumigatus were detected. Aspergillosis is a common fungal disease in birds, especially in immunosuppressed individuals or those with poor ventilation.

Your PSA is in the normal range. While PSA can be elevated by prostate cancer, BPH, prostatitis, and even vigorous exercise, a normal result is reassuring. PSA should be interpreted alongside digital rectal exam findings and age-specific norms.

Your free PSA ratio is in the intermediate range. This result alone does not strongly indicate or rule out prostate cancer and should be interpreted alongside your total PSA level, age, and clinical findings.

Your CA-125 is in the normal reference range. This is a reassuring finding, though CA-125 is not a perfect screening test for ovarian cancer and can be normal even when cancer is present in early stages.

Your CA 19-9 is in the normal range. This result does not suggest pancreatic, biliary, or colorectal pathology at this time.

Your CEA is in the normal range. This is a reassuring finding for colorectal cancer screening and post-treatment surveillance. Smokers have a slightly higher normal range of up to 5 ng/mL.

Your AFP is in the normal range. This does not suggest hepatocellular carcinoma, testicular germ cell tumor, or other AFP-producing malignancy at this time.

Your CA 15-3 is in the normal range. Mild elevation can occur with benign breast disease, liver disease, and other non-malignant conditions.

Your CA 27-29 is in the normal range, consistent with no significant breast cancer-related marker production.

Your hCG is in the normal range for a non-pregnant individual, consistent with no pregnancy and no detectable germ cell tumor marker production.

Your calcitonin is in the normal range, indicating no excessive C-cell production. Mild elevation can occur with C-cell hyperplasia, chronic kidney disease, and certain medications.

Your CgA is in the normal range. Note that proton pump inhibitors (PPIs) significantly elevate CgA and this should be accounted for when interpreting results.

Your NSE is in the normal range. Note that hemolyzed blood samples give falsely elevated NSE, so sample quality must be confirmed if results are unexpected.

A normal troponin I result means your heart muscle cells appear to be intact and not releasing distress signals. This is one of the key tests doctors use to rule out a heart attack, and a normal value is highly reassuring. Serial measurements are sometimes needed to fully is consistent with this.

A normal troponin T result is one of the strongest signs that an active heart attack is not occurring. The heart muscle releases this protein only when cells are injured. Your result shows no detectable release. Doctors often re-check this marker a few hours later to confirm this.

A normal BNP level indicates the heart is functioning without excessive pressure or fluid overload. BNP is one of the most reliable markers for heart failure, and a normal result makes significant heart failure unlikely. This result provides meaningful reassurance about cardiac function.

A normal NT-proBNP is one of the best tools available for ruling out heart failure. Values below 125 pg/mL (for patients under 75) have a very high negative predictive value for heart failure. Your heart is not under the kind of mechanical strain that would cause significant NT-proBNP release.

An hs-CRP (a blood marker of low-grade inflammation) between 1 and 3 mg/L places you in the average cardiovascular risk category for this marker. Some low-grade arterial inflammation is present, which contributes to the slow buildup of arterial plaque over time. This range is common in the general population but is not optimal.

Your homocysteine level is within the acceptable normal range. While not in the optimal zone below 10, this level is not associated with significant increased cardiovascular risk. Homocysteine rises when B vitamin intake is insufficient or kidney function declines slightly.

A normal Lp(a) below 30 mg/dL adds only modest cardiovascular risk. Lp(a) is a sticky lipoprotein particle that promotes plaque formation and blood clot development in arteries, but the normal range carries limited additional risk beyond standard cholesterol markers. This is predominantly genetically determined.

A normal ApoB (the protein that carries bad cholesterol particles) means the number of artery-damaging particles in your blood is within the accepted population range. However, even in the normal range there is ongoing potential for plaque development over decades. ApoB reflects all particles capable of embedding in arterial walls, not just LDL.

A normal ApoA-1 indicates adequate levels of this key HDL structural protein, supporting reasonable reverse cholesterol transport capacity. At this level, the body has sufficient ApoA-1 to carry out meaningful cholesterol removal from the arteries. Normal ApoA-1 is associated with average to moderate cardiovascular risk.

Normal fibrinogen means your blood has adequate clotting protein to form proper clots when needed, without being excessively prone to clot formation. This balance is important both for preventing excessive bleeding and for not generating unnecessary blood clots in the arteries or veins.

A normal MPO level means immune-driven vascular oxidative stress from this enzyme is within the expected population range. While not in the lowest-risk category, normal MPO does not represent significant added cardiovascular danger. MPO is most useful as an additional risk stratification tool alongside standard lipid panels.

A normal oxLDL means LDL oxidation is occurring at levels seen across the general population. While not notable, even normal oxLDL contributes to the slow buildup of arterial plaque over decades. The amount of oxidized LDL is influenced by dietary antioxidant intake, smoking, and overall oxidative stress.

Your white blood cell count is normal, suggesting your immune system is functioning without signs of active infection, major stress, or suppression.

Your red blood cell count is in the normal range, meaning your blood is capable of carrying adequate oxygen to all your tissues.

Your monocyte percentage is in the expected range.

Your eosinophil percentage is in the expected range.

Your basophil percentage is in the expected range.

Your tTG-IgA is within the normal range, meaning there is no detectable autoimmune response targeting tissue transglutaminase. This makes celiac disease very unlikely if your total IgA level is normal.

Your endomysial antibody test is negative. The EMA test is highly specific (>99%) for celiac disease, so a negative result makes active celiac disease very unlikely.

Your DGP IgA level is within the normal range, indicating no immune response to deamidated gliadin (a component of gluten). This test is useful in celiac disease diagnosis, particularly in children under 2 years old.

Your DGP IgG level is within the normal range. This test is particularly important for detecting celiac disease in individuals with IgA deficiency (who cannot mount an IgA response).

Your total IgA level is normal, which means the tTG-IgA test for celiac disease will work correctly. IgA deficiency is excluded as a cause of false negative celiac a blood antibody test.

You do not carry the HLA-DQ2 gene, which is the primary genetic risk factor for celiac disease. Approximately 95% of celiac patients carry either DQ2 or DQ8. A negative result makes celiac disease very unlikely.

You do not carry the HLA-DQ8 gene. DQ8 is the second major genetic risk factor for celiac disease (present in about 5% of celiac patients, usually those who are DQ2-negative).

Your Blood-thinning level (INR) is in the normal range, which means your blood is clotting at the right speed — not too fast, not too slow.

Your PTT result is normal. The intrinsic clotting pathway — the internal mechanism your body uses to stop bleeding — is functioning properly.

Your fibrinogen level is normal, meaning your blood has sufficient clotting material available to form proper clots when needed.

D-dimer measures fragments released when blood clots dissolve. A normal level effectively rules out a significant active blood clot in most clinical situations.

Protein C is functioning at normal levels, helping your body regulate clotting appropriately and preventing abnormal clot formation.

Protein S is functioning normally, helping to keep clotting regulated and prevent inappropriate clot formation in your vessels.

Antithrombin III is in the normal range, providing adequate natural protection against excessive clotting.

Factor VIII is at a normal level, ensuring your blood can clot properly when you're injured. This step in the clotting cascade is working as expected.

Your Factor V Leiden genetic test is normal. You don't carry this common inherited mutation that raises venous a clot forming risk.

Your Von Willebrand Factor is in the normal range, meaning your platelets should be able to adhere to injured vessels properly.

Your fasting glucose is in the healthy range. Your body is efficiently regulating blood sugar — insulin is working well and your cells are responding appropriately. This is the expected result for a healthy metabolic state.

A 2-hour postprandial glucose below 140 mg/dL is considered normal. Your body is efficiently clearing the post-meal glucose spike and returning to baseline, which indicates good insulin function and sensitivity.

An HbA1c (a 3-month average of your blood sugar) below 5.7% is classified as normal. Your red blood cells have been bathed in healthy glucose concentrations for the past 3 months. This indicates no diabetes and minimal insulin resistance.

Your fasting insulin is within the standard laboratory reference range. The lower end of this range (6–10 mcIU/mL) reflects good insulin sensitivity, while the upper end (15–20) begins to suggest early insulin resistance.

A HOMA-IR (a score that estimates insulin resistance) between 1 and 2 is within the accepted normal range for adults. Insulin sensitivity is adequate for maintaining blood sugar regulation without significant overproduction of insulin.

Your HOMA-B score is within the normal range, indicating adequate beta cell function and insulin secretory capacity.

Your C-Peptide is within the normal range, indicating your pancreatic beta cells are functioning and producing insulin. This helps is consistent with Type 2 diabetes (rather than Type 1) when blood sugar is elevated.

Your fructosamine is within the normal range, indicating your blood glucose has been well-managed over the past 2–3 weeks. This is a shorter-window complement to HbA1c (which reflects 3 months).

GAD65 antibodies below 5 IU/mL are within the normal reference range. Your immune system does not appear to be attacking the insulin-producing cells in your pancreas at a clinically significant level.

AST is an enzyme found in the liver and muscles. Your horse's levels are within the normal range, indicating no significant liver or muscle damage.

Albumin is a protein produced by the liver that helps maintain oncotic pressure and transport various substances. Normal levels indicate healthy liver function and nutrition.

Globulins include alpha, beta, and gamma globulins — primarily immunoglobulins (antibodies). Normal levels reflect a healthy immune system.

ACTH (adrenocorticotropic hormone) is produced by the pituitary gland and stimulates the adrenal glands to produce cortisol. Normal levels effectively rule out pituitary pars intermedia dysfunction (PPID, Equine Cushing's Disease). Note: ACTH levels are normally higher in the fall (August-October) due to seasonal variation.

Insulin regulates blood glucose. Normal resting insulin levels make equine metabolic syndrome (EMS) unlikely.

Normal fasting glucose makes insulin dysregulation less likely but does not rule it out — many EMS horses have normal glucose with high insulin.

The TRH stimulation test is the most sensitive test for PPID (Equine Cushing's Disease) in horses. Blood is drawn before and 10 minutes after TRH administration. In a normal horse, ACTH rises less than 2-3 times baseline. In PPID horses, there is an exaggerated ACTH response. This test is especially useful when resting ACTH is borderline or clinical signs suggest PPID despite normal resting ACTH.

No antibodies against equine infectious anemia virus (EIAV) were detected. The Coggins test (AGID) is the gold standard for EIA testing and is required for interstate travel and most equine events. EIA is a viral disease transmitted by blood-feeding insects (horse flies, deer flies).

No significant changes in EHV-1/4 antibody titers were detected. Negative a blood antibody test makes active infection unlikely, though many adult horses have low background titers from prior exposure or vaccination. Paired acute and convalescent titers (2-4 weeks apart) provide the most reliable diagnosis.

No IgM antibodies against West Nile virus were detected. IgM a blood antibody test is used to detect recent or active infection because IgM appears within days of infection and declines after 1-2 months. IgG testing can differentiate past vaccination from natural infection.

No significant antibodies against Streptococcus equi subsp. equi (the bacterium that causes strangles) were detected. This makes recent or active infection unlikely. Negative a blood antibody test is also useful to confirm a horse is a non-carrier before introducing to a new herd or before an event.

Your total IgE is within the normal range. IgE is the antibody involved in allergic reactions. Normal levels suggest no systemic allergic tendency, though organ-specific allergies (like hay fever) can still occur.

Your IgD level is within the expected normal range. IgD is present at low levels and its function is not fully understood.

Your free kappa light chain level is normal. The kappa/lambda ratio is the more important indicator of clonality.

Your free lambda light chain level is normal. The kappa/lambda ratio is the more important indicator of clonality.

Your free light chain ratio is within the normal range, indicating a balanced production of kappa and lambda light chains. This effectively rules out most clinically significant light chain-related plasma cell disorders.

Fructosamine shows your average blood sugar over the last 2-3 weeks. It's like a 'mini A1c'. Your level is in a healthy, stable range.

LDL is only truly dangerous when it gets 'oxidized' (damaged). Your level is low, meaning your body is protecting your cholesterol from damage.

A score of 0 means there is no hard plaque (calcification) seen in your coronary arteries. This puts you at a very low risk of a heart attack in the next 10 years.

Hydrogen levels stayed low throughout the test, suggesting no overgrowth of hydrogen-producing bacteria in your small intestine.

A normal CRP within the accepted reference range means no significant acute inflammatory process is currently detected. CRP can rise within hours of an infection or inflammatory injury and returns to baseline within days to weeks. A normal CRP helps rule out major acute inflammation, though chronic low-grade inflammation can exist with CRP in the low-normal range.

A normal ESR means inflammation-related plasma proteins are not present in quantities that noticeably accelerate red blood cell sedimentation. While ESR is a non-specific test (many conditions raise it), a normal value effectively argues against significant active inflammation, serious infection, or autoimmune disease activity. ESR rises with age and is slightly higher in women.

A normal IL-6 within the reference range means the immune system is not mounting an excessive inflammatory signaling response. IL-6 drives many downstream inflammatory effects — fever, acute-phase protein production, immune cell activation — and a normal level is consistent with these pathways are not being overactivated.

Normal TNF-alpha means immune concern signaling through this potent cytokine is within the expected population range. TNF-alpha is one of the master switches of the inflammatory response, and normal levels indicate the immune system is not in a state of excessive or dysregulated activation.

Normal fibrinogen means adequate clotting capacity is present without excess blood-thickening inflammatory protein in circulation. Fibrinogen is both a clotting factor and an acute-phase inflammatory reactant — normal levels suggest no significant inflammatory activation and adequate hemostatic reserve.

Normal ferritin means iron reserves are within the accepted range. When ferritin is also within the optimal subrange, energy production, immune function, and red blood cell production are all well-supported by iron availability. Normal ferritin rules out both iron deficiency and iron overload at a basic screening level.

A normal neutrophil percentage reflects a healthy distribution of immune cell types in the blood. Neutrophils at 40–70% of white cells is the expected proportion in a healthy immune system. This normal ratio helps is consistent with that neither bacterial infection nor immune suppression is noticeably shifting the white cell balance.

Normal procalcitonin below 0.1 ng/mL is consistent with no significant systemic bacterial infection is producing PCT above baseline. This is the major clinical utility of PCT — at normal levels, antibiotics for systemic bacterial infection are generally not indicated. PCT may still be slightly elevated in some non-bacterial conditions but remains below clinically actionable thresholds.

Normal C3 means the complement protein system is not being noticeably consumed or deficient. This is reassuring against active immune complex disease or major complement pathway activation. Normal C3 combined with normal C4 makes autoimmune complement consumption unlikely.

Normal C4 means the classical complement pathway proteins are not being abnormally consumed or deficient. This reduces the likelihood of active immune complex-mediated complement consumption from diseases like lupus. Normal C4 alongside normal C3 makes active autoimmune complement depletion unlikely.

Normal SAA below 10 mg/L means the acute-phase response is not noticeably activated. While mildly elevated SAA (2–10 mg/L) can reflect very low-grade chronic inflammation, a normal result does not indicate concerning inflammatory disease activity. This marker is most useful for monitoring known inflammatory diseases rather than screening.

Normal Lp-PLA2 below 200 ng/mL places you in the lower cardiovascular risk category for this marker. While not in the optimal low zone, this level does not indicate high vascular inflammation from this enzyme. Lp-PLA2 is best used as one component of comprehensive cardiovascular risk assessment.

Your serum iron is in the normal range, indicating adequate circulating iron for red blood cell production and cellular function.

Your TIBC is normal, indicating your blood has the appropriate capacity to bind and transport iron to the bone marrow and other tissues.

Your transferrin saturation is in the normal range, indicating adequate iron is being carried through your bloodstream to the bone marrow and tissues.

Your ferritin is within the standard laboratory reference range, indicating you have sufficient iron stored to meet your body's needs without active iron deficiency.

Your transferrin level is normal, indicating good liver production of this iron-carrying protein and appropriate iron transport capacity.

Normal hemosiderin indicates adequate iron storage in body tissues, supporting ongoing iron availability for red blood cell production and cellular function.

Your sTfR is normal, indicating appropriate iron demand from your bone marrow and tissues. Normal sTfR alongside normal ferritin suggests healthy iron stores and erythropoiesis.

A normal serum creatinine means your kidneys are clearing this muscle waste product at a healthy rate. Since creatinine is produced continuously by muscles and filtered out entirely by healthy kidneys, a normal level indicates the filtration system is functioning well. Normal creatinine is a basic but important indicator of kidney health.

An eGFR (a number that shows how well your kidneys filter your blood) between 45 and 59 represents mildly to moderately reduced kidney function, classified as CKD Stage 3a. While the kidneys are still managing basic functions, long-term progressive damage is a concern. Cardiovascular risk is elevated at this stage, and further decline without intervention is common.

A normal BUN means the kidneys are effectively filtering urea (a byproduct of protein breakdown) from the blood. This result, in combination with creatinine and eGFR (a number that shows how well your kidneys filter your blood), provides reassurance about basic kidney function. Normal BUN reflects appropriate protein metabolism and adequate kidney filtration.

A normal BUN/Creatinine ratio of 10–20 indicates a healthy balance between protein metabolism and kidney filtration. This ratio helps distinguish between dehydration (raises both BUN and ratio), kidney disease (raises creatinine more), and liver disease (lowers BUN and ratio). A normal ratio in this context points to generally healthy kidney and liver function.

A normal Cystatin C indicates that kidney filtration is within the expected population range. While not in the optimal low zone, this level does not suggest significant kidney impairment. Cystatin C is particularly useful when creatinine gives ambiguous results due to body composition differences.

A normal urine albumin below 30 mg/g means the kidneys are maintaining their protein filtration barrier. Small amounts below this threshold can occur naturally and are not clinically significant. This result effectively rules out microalbuminuria, which is an early warning sign of diabetic or hypertensive kidney damage.

A normal urine creatinine is consistent with the sample is adequately concentrated to provide reliable results for other urine markers. The kidneys are concentrating creatinine normally as they process urine, which is a basic function that remains intact until kidney disease is moderate to noticeable.

A normal ACR below 30 mg/g means albumin loss into the urine is within the normal range. The kidney filter is maintaining protein retention adequately. This result effectively rules out current microalbuminuria, though annual monitoring is important for at-risk individuals.

A normal uric acid level means urate is within the acceptable range where crystal formation in joints or kidneys is unlikely. At normal levels, uric acid acts as an antioxidant in the blood without triggering the inflammatory joint or kidney complications seen at high levels. This is a reassuring result.

Total protein reflects albumin and globulin levels. Rabbits and guinea pigs have protein levels similar to other mammals. Normal levels indicate good nutrition and immune function.

Albumin is produced by the liver and maintains fluid balance. Normal levels indicate healthy liver function and nutritional status.

Globulins include antibodies and immune proteins. Normal levels indicate an appropriately functioning immune system.

CK is a muscle enzyme. Normal levels indicate no significant muscle damage.

BUN reflects kidney function and protein metabolism. Rabbits have relatively low BUN compared to carnivores. Normal levels indicate good kidney filtration.

Creatinine is a waste product from muscle metabolism that is filtered by the kidneys. Normal levels indicate effective kidney filtration.

Glucose is the main energy source. Rabbits have relatively stable blood glucose. Normal levels indicate good energy metabolism and pancreatic function.

Rabbits and guinea pigs are unique among mammals in that they absorb dietary calcium efficiently regardless of need, resulting in naturally high blood calcium levels (11-15 mg/dL). This is normal and not a sign of disease as it would be in other species.

White blood cells protect against infections. Rabbits have lower WBC counts than dogs and cats. Normal levels indicate a healthy immune system.

Hematocrit measures the proportion of red blood cells. Normal levels indicate good oxygen carrying capacity and no significant anemia or dehydration.

No antibodies against Pasteurella multocida were detected. This bacterium is a common cause of respiratory disease (snuffles), abscesses, and reproductive infections in rabbits.

No antibodies against Encephalitozoon cuniculi were detected. This protozoal parasite can cause kidney disease, neurological signs (head tilt, rolling), and eye problems in rabbits.

Normal WBC indicates a healthy immune system with no obvious signs of active systemic infection or very large stress.

Indicates a stable immune system without noticeable infection.

Healthy immune function.

Your total cholesterol is within the desirable range, indicating manageable cardiovascular risk from this marker alone. The breakdown of HDL, LDL, and triglycerides provides more specific information.

Your LDL cholesterol is within the acceptable range (100–129 mg/dL is near-optimal). LDL deposits cholesterol in artery walls over time, so lower is generally better for long-term heart health.

Your HDL is within the normal range, providing reasonable artery-cleaning function. Higher HDL provides more protection, so there is benefit in improving this if possible.

Your triglycerides are below 150 mg/dL, which is the desirable range. This indicates your body is handling dietary fats and sugars efficiently without excess fat accumulating in the bloodstream.

Your VLDL level is in the acceptable range. VLDL carries triglycerides from the liver to tissues — normal levels indicate the liver is not overloaded with fat storage.

Your non-HDL cholesterol (which includes LDL, VLDL, and IDL) is in the normal range. This is considered a more complete measure of cardiovascular risk from cholesterol than LDL alone.

A ratio of 2–3 is acceptable for most adults. While not optimal, it reflects a manageable balance between protective and harmful cholesterol.

Your total cholesterol to HDL ratio is in the normal range, indicating moderate (not elevated) cardiovascular risk from this metric.

Your ApoB (the protein that carries bad cholesterol particles) level is in the normal range. ApoB is considered one of the best measures of cardiovascular risk because each LDL, VLDL, and IDL particle carries exactly one ApoB protein.

A normal ALT level means liver cells are generally intact and not noticeably damaged or inflamed. ALT is one of the most sensitive markers for liver cell injury and a normal result effectively rules out significant active hepatitis or toxic liver injury. Normal ALT alone does not rule out all forms of liver disease, but it is reassuring.

A normal AST level indicates that liver, muscle, and other tissues are not releasing this enzyme in abnormal quantities. While AST is less liver-specific than ALT (it also rises with muscle and heart injury), a normal level in the context of a full liver panel is reassuring for hepatic health. When AST and ALT are both normal, significant liver disease is unlikely.

A normal ALP level means no significant obstruction of bile ducts, no bone disease driving ALP elevation, and no signs of infiltrative liver disease. ALP is particularly useful for detecting bile duct obstruction and cholestatic liver disease, and a normal level provides meaningful reassurance against these conditions.

A normal GGT level means the liver is not under significant induction stress from alcohol, medications, or bile duct obstruction. GGT is particularly useful for confirming liver-source ALP elevations, and a normal GGT together with normal ALP provides strong reassurance about bile duct health. GGT rises quickly with even moderate alcohol use.

A normal bilirubin means red blood cell waste products are being processed and eliminated by the liver without accumulation. Normal bilirubin makes jaundice (yellowing of skin and eyes) essentially impossible. This requires the liver to be functioning adequately in its bilirubin conjugation and excretion steps.

Normal direct bilirubin is consistent with adequate hepatic conjugation and biliary excretion of bilirubin. When total bilirubin is elevated but direct bilirubin is normal, the cause is likely pre-hepatic (hemolysis) or Gilbert's syndrome (impaired uptake). When direct bilirubin is elevated alongside total bilirubin, liver disease or bile duct obstruction is more likely.

A normal albumin is consistent with the liver has sufficient synthetic capacity to produce adequate levels of this key protein. Since albumin production is one of the liver's core functions and one of the last to fail in progressive liver disease, a normal albumin provides meaningful reassurance about liver synthetic reserve. Normal albumin also supports proper fluid balance throughout the body.

A normal prothrombin time is consistent with that the liver is producing adequate clotting factors (Factors II, VII, IX, X, and V) and that the extrinsic clotting pathway is functioning normally. PT is a sensitive marker of liver synthetic function and vitamin K status. A normal result is reassuring for both liver function and clotting health.

A normal Blood-thinning level (INR) between 0.8 and 1.2 is consistent with that clotting factors are being produced by the liver in adequate quantities and that vitamin K-dependent pathways are functioning normally. For patients not on blood-thinning treatment, this provides strong reassurance about both liver synthetic function and clotting health.

A balanced AST/ALT ratio between 0.7 and 1.0 does not point to a specific liver disease pattern. This ratio is most clinically useful when enzymes are elevated — a normal ratio provides limited standalone information. It is consistent with no clear dominance of AST (suggesting alcoholic or non-hepatic origin) or ALT (suggesting acute hepatocellular disease).

An FLI in the 30–60 range represents intermediate risk of hepatic steatosis. The component markers (BMI, waist circumference, GGT, triglycerides) are collectively pointing to a growing possibility of liver fat accumulation. This is a common finding in metabolically active middle age and does not is consistent with fatty liver but suggests liver ultrasound would be informative.

Your SIRT1 activity is within the normal range. This indicates adequate longevity pathway activation.

Your mTOR is within the normal range, reflecting a balanced state between cellular growth/repair and cellular maintenance/autophagy.

Your p62 is within the normal reference range, consistent with adequate autophagy function.

Your skin AGEs are in the normal range for age. Some glycation accumulation is a normal feature of aging, and this level is within the expected range.

A normal morning cortisol within the reference range is consistent with the adrenal glands are producing cortisol in the expected circadian morning surge. This result is compatible with healthy your brain–adrenal stress system function. Context matters — even a normal absolute value should be interpreted alongside ACTH levels, DHEA-S (a partner-hormone to cortisol), and clinical symptoms for full adrenal health assessment.

A normal DHEA-S (a partner-hormone to cortisol) level within the reference range indicates adequate adrenal production of this key anti-aging, anti-stress steroid. Normal DHEA-S (a partner-hormone to cortisol) supports sex hormone balance, immune function, brain health, and acts as a natural buffer against the catabolic effects of cortisol excess.

Normal TSH (the signal hormone your brain sends to your thyroid) means the thyroid is producing adequate amounts of hormone to support brain function, mood regulation, energy metabolism, and cognitive performance. Thyroid hormones are essential for brain development and ongoing neurological function — normal levels support normal neurotransmitter balance, mood stability, and cognitive clarity.

A normal vitamin D within the reference range supports basic bone health and immune function. However, from a mental health optimization perspective, the conventional normal range (>20 ng/mL) may be insufficient for optimal brain function. The optimal range for mood and cognitive health is generally considered 40–60 ng/mL.

Normal serum magnesium means the bloodstream is maintaining adequate magnesium concentration. However, serum magnesium represents only 1% of total body magnesium — most is stored intracellularly and in bone. Normal serum levels can coexist with intracellular deficiency. Clinical symptoms matter alongside this test result.

A normal serum zinc level indicates adequate circulating zinc for basic physiological functions. However, like magnesium, serum zinc is not fully reflective of intracellular and tissue zinc status — true functional zinc deficiency can exist with normal serum levels. If symptoms of zinc deficiency persist, RBC zinc or alkaline phosphatase (zinc-dependent enzyme) can provide additional information.

A B12 level in the normal range satisfies conventional laboratory criteria. However, from a brain health perspective, the optimal range for cognitive function and mood is considered to be above 500 pg/mL by many researchers. Serum B12 may also not fully reflect cellular B12 adequacy — methylmalonic acid is a better functional marker.

Normal folate provides adequate support for basic one-carbon metabolism, DNA synthesis, and neurotransmitter production. From a mental health optimization perspective, levels above 10 ng/mL are generally preferred to ensure robust methylation chemistry for optimal serotonin and dopamine synthesis.

An omega-3 index between 4 and 8% is in the normal range for most Western populations. However, research consistently shows that the greatest brain health, mood, and cardiovascular benefits occur at levels above 8%. Even a 'normal' omega-3 index may leave room for meaningful improvement in mood stability, cognitive performance, and anti-inflammatory protection.

Normal whole blood serotonin is consistent with adequate serotonin production and storage in the gut and platelets. This is a reasonable proxy for peripheral serotonin status, though it should be noted that brain serotonin neurotransmission cannot be directly measured and may differ from peripheral blood levels. Normal blood serotonin does not rule out serotonin-related mood disorders.

Normal urinary dopamine reflects adequate peripheral catecholamine production. This result is compatible with healthy dopaminergic system activity. Interpretation of urinary dopamine requires careful clinical context — single time-point measurements can vary widely with diet (tyrosine intake), activity level, and stress state.

Normal urinary norepinephrine reflects adequate sympathetic nervous system catecholamine production and excretion. This is compatible with healthy alertness, attention, blood pressure regulation, and stress response capacity.

A normal whole blood histamine level is within the expected range for healthy individuals. Normal histamine supports proper immune mast cell function, gastric acid secretion, and brain histaminergic neurotransmission (wake-sleep regulation, appetite control). This result does not indicate significant histamine metabolism dysfunction.

Normal kryptopyrrole levels below 10 mcg/dL are accepted as not clinically significant for pyroluria. While some HPL excretion is normal from heme synthesis, this level does not cause significant ongoing B6 and zinc depletion. Note that kryptopyrrole testing is primarily used in integrative and functional medicine — it is not a standard laboratory test in conventional medicine.

Cortisol is a stress hormone produced by the adrenal glands. This baseline reading shows resting adrenal function.

The adrenal glands produced a normal surge of cortisol in response to synthetic ACTH. This rules out both Addison's disease and Cushing's disease with high confidence.

This is the resting cortisol drawn before dexamethasone is administered. It provides the reference point for the 4-hour and 8-hour post-dexamethasone samples.

Dexamethasone is a synthetic steroid that normally suppresses ACTH release, which in turn lowers cortisol. The 8-hour level being below 1.5 µg/dL means the negative feedback loop is working normally. This rules out Cushing's disease.

The urine cortisol:creatinine ratio normalizes the cortisol level to urine concentration. A value below 30 rules out Cushing's disease with high certainty. This is an excellent screening test.

Aldosterone is a mineralocorticoid hormone produced by the adrenal glands. It regulates sodium, potassium, and fluid balance. A normal level means electrolyte regulation is functioning properly.

CMV IgG positive means you were infected with CMV at some point — likely years ago with no symptoms. The virus remains dormant in your body like all herpesviruses. You now have lifelong immunity against new primary CMV infection.

EBV VCA IgG positive means you were previously infected with EBV — most likely in childhood or adolescence as typical infectious mononucleosis. The virus remains dormant but you now have lifelong immunity against re-infection.

Toxoplasma IgG positive means you were infected at some point in the past and are now immune. In healthy adults, this past infection typically causes no ongoing problems.

Your vancomycin trough level is within the target therapeutic range. The drug concentration is high enough to effectively treat the infection but not so high as to significantly increase kidney toxicity risk.

Your digoxin level is within the target therapeutic range, providing optimal benefit for heart failure (improved contractility) or atrial fibrillation (rate control) while minimizing toxicity risk.

Your lithium level is within the target therapeutic range, providing effective prophylaxis against bipolar mood episodes. The specific target (0.6–0.8 for maintenance, 0.8–1.2 for acute treatment) depends on your clinical situation.

Your cyclosporine level is within the target therapeutic range, providing effective immunosuppression to prevent organ rejection.

Your methotrexate level is below the toxicity threshold (<0.1 µmol/L at 42 hours or <0.05 µmol/L at 72 hours). This indicates the drug has been adequately cleared and leucovorin rescue is working.

Your gentamicin trough level is below 2 µg/mL, which is the target to minimize the risk of nephrotoxicity and ototoxicity (hearing loss/balance problems). Trough levels are the best predictor of toxicity risk.

Your gentamicin peak level is within the target range. For concentration-dependent aminoglycosides, the peak concentration relative to the MIC is the key determinant of bacterial killing.

Your theophylline level is within the target therapeutic range, providing effective bronchodilation for asthma or COPD. At these levels, the drug also has anti-inflammatory effects and improves diaphragmatic function.

Your TSH (the signal hormone your brain sends to your thyroid) is within the normal range, suggesting your thyroid is receiving and responding to appropriate signals from the brain. Thyroid function is likely adequate.

Your free T4 (the main thyroid hormone in your blood) level is normal, indicating your thyroid is producing adequate hormone for normal metabolic function.

Your free T3 (the active thyroid hormone your cells actually use) is within the normal range, indicating adequate delivery of active thyroid hormone to your cells.

Your total T4 is within the reference range. Note that this test measures both bound and free T4 (the main thyroid hormone in your blood) — free T4 is a more specific indicator of active thyroid hormone.

Your total T3 is within the reference range, suggesting adequate active thyroid hormone in circulation.

Your reverse T3 level is within normal limits. Reverse T3 is an inactive form of thyroid hormone that competes with active T3 at cell receptors. Normal levels mean this competition is not excessive.

Your TPO antibody level is below the threshold that indicates autoimmune thyroid disease. Your immune system is not mistakenly targeting your thyroid at a clinically significant level.

Your thyroglobulin antibody level is within the normal range, indicating no significant autoimmune attack on your thyroid's protein machinery.

Thyroglobulin is a protein produced by thyroid cells. In people with an intact thyroid, normal levels indicate normal thyroid tissue activity. In thyroid cancer surveillance, any detectable thyroglobulin after thyroidectomy warrants attention.

Your T3 uptake is within the expected range. This supports a balanced thyroid-binding protein picture when the rest of the thyroid panel is also in range.

A normal urine pH between 4.5 and 8.0 reflects normal kidney acid-base regulation. The kidneys adjust urine pH continuously to maintain blood pH balance, making urine pH highly variable throughout the day. A spot pH in this range is within the normal physiological range.

A normal urine specific gravity means the kidneys are appropriately concentrating or diluting urine based on the body's fluid needs. The wide range (1.005–1.030) reflects the kidney's remarkable ability to adapt urine concentration to hydration status throughout the day. A normal value confirms basic kidney concentrating and diluting function is intact.

Negative or trace urine protein on dipstick is within the expected normal range for a general screening test. The dipstick detects primarily albumin and is positive at concentrations above approximately 10–20 mg/dL. A negative or trace result in a spot specimen is not concerning on its own.

Normal urine glucose is negative — the kidneys efficiently reabsorb all filtered glucose back into the bloodstream in people with healthy blood sugar levels. A negative urine glucose provides reassurance against noticeable hyperglycemia, though mildly elevated blood sugar below the kidney threshold may still be present even with a negative result.

Normal urine ketones are negative in individuals eating regular meals. Ketones appear when the body is starved of glucose and begins burning fat, producing ketone bodies (beta-hydroxybutyrate, acetoacetate, acetone) as a byproduct. A negative result confirms glucose metabolism is the primary fuel pathway.

A normal negative urine bilirubin confirms healthy bilirubin metabolism. Only conjugated (direct) bilirubin can pass through the kidneys into urine — and this only happens when blood conjugated bilirubin is elevated due to liver disease or bile duct obstruction. A negative result effectively rules out hepatobiliary disease causing conjugated hyperbilirubinemia.

Normal urine urobilinogen of 0.1–1.0 EU/dL confirms that bilirubin is flowing normally from the liver through bile into the intestines where bacteria convert it to urobilinogen, which is then partially excreted in urine. This normal cycle indicates no significant bile obstruction and reasonably intact liver-gut bilirubin processing.

Normal negative urine nitrites, combined with negative leukocyte esterase, makes an active bacterial UTI significantly less likely. This combined negative result (negative nitrites AND negative leukocyte esterase) has a high negative predictive value for UTI.

Normal negative leukocyte esterase is the expected result in healthy individuals. The urinary tract is not under active immune attack from white cells, confirming no significant bacterial infection or inflammatory kidney disease is present at the time of testing.

Up to 3 red blood cells per HPF is accepted as the upper limit of normal in most laboratories. This level is not significant hematuria. In the context of a clean-catch specimen without menstrual contamination or vigorous exercise, up to 3 RBCs per HPF reflects normal urinary tract health.

Up to 5 WBCs per HPF is the accepted upper limit of normal. This level does not represent significant pyuria and does not indicate urinary tract infection or inflammatory kidney disease. Normal WBC count in urine is a reassuring basic indicator of urinary tract health.

Up to 2 hyaline casts per HPF is within the accepted normal range. Hyaline casts in this quantity are benign and physiological. Pathological casts — granular, waxy, RBC, WBC, or fatty casts — would be the concerning finding, not a modest number of pure hyaline casts.

None to rare crystals on urine microscopy is the normal finding. The kidneys are not producing conditions favorable for significant crystal precipitation. Normal crystal results do not predict kidney stone formation risk unless stone-forming crystal types are present.

None to rare bacteria in urine is consistent with an infection-free urinary tract. Truly sterile midstream urine confirms no significant bacterial colonization of the bladder or urethra. This is the expected result in a healthy, asymptomatic individual.

A normal 24-hour urine protein below 150 mg/day is within the physiological normal range. Small quantities of filtered proteins and tubular secretions account for this baseline, and values below 150 mg/day do not constitute proteinuria. This is the gold-standard method for confirming absence of significant protein loss.

A normal urine osmolality within 300–900 mOsm/kg reflects appropriate kidney concentrating or diluting response to the body's current hydration state. Normal kidneys can concentrate urine up to 1200 mOsm/kg (maximum) and dilute it to approximately 50 mOsm/kg (minimum) as needed. This result confirms basic concentrating and diluting function is intact.

Vitamin D in the 30–49 ng/mL range is sufficient to prevent deficiency-related diseases. Calcium absorption, bone mineralization, and basic immune function are supported.
