Order Parathyroid Hormone (PTH) Test | Lab TestThe parathyroid hormone (PTH) test measures the amount of PTH in the blood. PTH is produced by the parathyroid glands, four small glands located behind the thyroid in the neck. This hormone is central to calcium regulation: it raises blood calcium by acting on bone, kidneys, and the intestine. Because PTH and calcium work in a tight feedback loop, the test is usually interpreted alongside a calcium measurement rather than on its own.
About Parathyroid Hormone (PTH) Test | Lab Test in Collierville
PTH testing helps evaluate calcium balance and parathyroid gland function.
PTH is secreted when blood calcium falls. It stimulates release of calcium from bone, increases calcium reabsorption in the kidneys, and activates vitamin D to boost intestinal calcium absorption. When calcium rises, PTH secretion normally drops.
A PTH result is most useful when paired with a simultaneous calcium level. High PTH with high calcium points toward overactive parathyroid glands, while high PTH with low calcium can reflect a normal response to calcium loss or a secondary cause. Low PTH with high calcium suggests a different problem.
The test is used in the workup of suspected hyperparathyroidism or hypoparathyroidism, unexplained high or low calcium, kidney stones, bone loss, and some thyroid or neck surgeries. Results are interpreted by a clinician in the context of symptoms, medications, kidney function, and vitamin D status.
