Parathyroid Hormone (PTH), Intact

Our Price:
PTH is produced in the parathyroid glands located behind the thyroid. More PTH is released when blood calcium levels are too low, and less PTH is released when calcium levels are high. The release of PTH triggers the bones to release calcium in the blood and tells the kidneys to reduce the amount of calcium released into the urine. PTH also helps facilitate the conversion of vitamin D, allowing the intestines to absorb additional phosphorus and calcium.

The PTH blood test is helpful for pinpointing causes of abnormal levels of calcium in the blood, since PTH in part controls calcium blood levels. The test can also help to evaluate parathyroid function and help with the diagnosis of hyperparathyroidism and other parathyroid diseases, including hypoparathyroidism and parathyroid carcinoma, as well as diseases of calcium homeostasis. Monitoring PTH levels is important because levels that are out of range can cause kidney problems, bone damage and changes in vitamin D and calcium levels. Patients undergoing renal dialysis usually require this test. The PTH blood test can single out primary, secondary or tertiary hyperparathyroidism and, in the cause of removal, confirm that the gland has been fully removed.
