Order Parathyroid Hormone (PTH) Test | Lab TestParathyroid hormone, or PTH, is a peptide secreted by the parathyroid glands that serves as the principal regulator of calcium balance in the body. A PTH blood test measures the concentration of this hormone in the circulation, giving clinicians a direct view of how the parathyroid glands are functioning and how they interact with calcium and phosphorus metabolism.
About Parathyroid Hormone (PTH) Test | Lab Test in Ithaca
The PTH test is a laboratory blood test that quantifies the amount of parathyroid hormone present in a blood sample.
PTH is released by four small parathyroid glands located near the thyroid gland in the neck. When blood calcium levels fall, the glands increase PTH secretion, which in turn prompts the kidneys to retain calcium, the bones to release calcium, and the intestines to absorb more calcium through activated vitamin D. When calcium levels rise, PTH secretion normally decreases.
Measuring PTH is most useful when interpreted alongside a simultaneous calcium measurement. A high PTH with a high calcium level can indicate primary hyperparathyroidism, while a high PTH with a low calcium level may point to secondary hyperparathyroidism, often related to kidney disease or vitamin D deficiency. A low PTH with a high calcium level can suggest a non-parathyroid cause of hypercalcemia.
The test requires a blood draw, typically from a vein in the arm. Results are generally available within one to three business days. Preparation instructions should be followed as provided by the laboratory performing the collection, since factors such as timing and certain medications can influence PTH levels.
