Your fecal lactoferrin is in the normal range, consistent with no active intestinal inflammation.
No fecal lactoferrin was detected. Lactoferrin is released by activated neutrophils in the intestine. An undetectable level indicates no significant neutrophilic gut inflammation.
No action needed. Excellent gut inflammation baseline.
Fecal lactoferrin undetectable — no intestinal neutrophil activityYour fecal lactoferrin is within the normal reference range. This suggests no significant intestinal inflammation and helps differentiate IBD from functional bowel conditions.
No action needed. Functional gut conditions are more likely if you have gastrointestinal symptoms.
Fecal lactoferrin within normal reference range — no significant intestinal inflammationYour fecal lactoferrin is in the low-normal range, indicating minimal intestinal neutrophil activity.
No action needed.
Fecal lactoferrin: low-normal — minimal intestinal inflammationYour fecal lactoferrin is in the normal range, consistent with no active intestinal inflammation.
No specific action required.
Fecal lactoferrin within reference range — normal gut inflammation markerYour fecal lactoferrin is in the optimal range, reflecting very low intestinal neutrophil activation.
No action needed.
Fecal lactoferrin: optimal — very low intestinal inflammationYour fecal lactoferrin is mildly above the reference range. This indicates mild intestinal neutrophil activation that could reflect early IBD, infectious gastroenteritis, NSAID-induced enteropathy, or other inflammatory gut conditions.
Discuss with your doctor. Repeat testing after 4–6 weeks and consider colonoscopy if elevation persists.
Fecal lactoferrin slightly elevated — mild intestinal inflammation; investigation warrantedYour fecal lactoferrin is significantly elevated, confirming active intestinal inflammation. This level is associated with IBD, bacterial enteric infections, and colorectal polyps or malignancy. Functional conditions like IBS do not typically elevate lactoferrin.
Seek gastroenterology referral. Stool cultures, C. difficile testing, and colonoscopy should be arranged. Elevated lactoferrin in the context of IBD suggests active disease requiring treatment adjustment.
Fecal lactoferrin >7.25 mcg/mL — elevated; active gut inflammation confirmedYour fecal lactoferrin is critically elevated, indicating noticeable active intestinal inflammation. This level is associated with noticeable IBD flare, acute noticeable colitis, or serious intestinal infection. Urgent clinical evaluation is required.
Seek urgent gastroenterology evaluation. Hospitalization and intensive treatment may be required if IBD flare is the cause.
