Your PTH is within the normal range, indicating appropriate parathyroid regulation of calcium, phosphate, and vitamin D metabolism.
Very low PTH (hypoparathyroidism) means the parathyroid glands have nearly stopped working. Without PTH, calcium levels drop very low, causing tetany (muscle spasms), seizures, and cardiac arrhythmias.
Seek urgent medical care. This is often an emergency requiring immediate calcium and PTH-related therapy, especially after thyroid or parathyroid surgery.
PTH: {{value}} {{unit}} — very low (ref: {{low}}–{{high}})Low PTH is normal when calcium is high (the body suppresses PTH when calcium is adequate). If calcium is also low, hypoparathyroidism is the concern. If calcium is high but PTH is low, a non-PTH cause of hypercalcemia (like malignancy) should be investigated.
Interpret alongside calcium. If calcium is low-normal and PTH is low, parathyroid function needs evaluation.
PTH: {{value}} {{unit}} — below reference range (ref: {{low}}–{{high}})Borderline low PTH is often a normal response to adequate or slightly high calcium levels. The interpretation depends very on the simultaneous calcium level.
Check calcium. If calcium is also low, parathyroid function should be formally assessed.
PTH: {{value}} {{unit}} — borderline lowYour PTH is within the normal range, indicating appropriate parathyroid regulation of calcium, phosphate, and vitamin D metabolism.
No action needed. Evaluate alongside calcium and vitamin D for complete picture.
PTH: {{value}} {{unit}} — within reference rangeYour PTH is in the healthy midrange, supporting appropriate calcium absorption, bone remodeling, and phosphate regulation.
No action needed.
PTH: {{value}} {{unit}} — optimalBorderline high PTH is most commonly a response to vitamin D deficiency or low calcium intake. When vitamin D is low, calcium absorption falls, and the parathyroid glands produce more PTH to maintain calcium levels by increasing bone resorption.
Check vitamin D levels. Supplementing vitamin D (if deficient) often normalizes PTH. Increase calcium and vitamin D intake.
PTH: {{value}} {{unit}} — borderline highElevated PTH (hyperparathyroidism) may contribute to the parathyroid to continuously leach calcium from bones into the blood. Over time, this may contribute to osteoporosis, kidney stones, fatigue, and mood changes. Primary hyperparathyroidism (parathyroid adenoma) is very common, especially in older women.
See your doctor. Check calcium, vitamin D, and a 24-hour urine calcium. Parathyroid ultrasound and DEXA bone density scan are typically recommended. Surgery to remove the overactive parathyroid is curative in most cases.
PTH: {{value}} {{unit}} — above reference range (ref: {{low}}–{{high}})Very high PTH is seen in noticeable secondary or tertiary hyperparathyroidism (most commonly from chronic kidney failure), or a large primary parathyroid tumor. At this level, bone destruction is occurring rapidly and the risk of kidney stones, cardiac calcification, and fractures is very high.
Seek urgent endocrinology or nephrology care. Treatment depends on the cause — surgical removal for primary adenoma, or medical management for kidney hyperparathyroidism.
