Order Parathyroid Hormone (PTH) Test | Lab TestThe parathyroid hormone (PTH) test measures the amount of parathyroid hormone circulating in the blood. PTH is produced by the parathyroid glands, four small glands located behind the thyroid, and it plays a central role in regulating calcium and phosphorus balance. Because PTH works in close feedback with calcium, the test is most informative when interpreted alongside calcium and, in some cases, phosphorus and vitamin D results.
About Parathyroid Hormone (PTH) Test | Lab Test in Lathrop
PTH testing is used to evaluate parathyroid function and to investigate disorders of calcium homeostasis.
Parathyroid hormone raises blood calcium by promoting release of calcium from bone, increasing calcium reabsorption in the kidneys, and activating vitamin D, which in turn increases intestinal calcium absorption. When calcium levels fall, PTH normally rises; when calcium levels rise, PTH normally falls.
A PTH result is generally interpreted together with a simultaneous calcium measurement. Patterns such as high PTH with high calcium, high PTH with low or normal calcium, and low PTH with high calcium point toward different explanations, including primary hyperparathyroidism, secondary hyperparathyroidism, and non-parathyroid causes of elevated calcium.
PTH testing may be ordered when calcium is abnormal, when there are symptoms or findings that suggest parathyroid disease, or during monitoring of a known parathyroid or kidney-related condition. Results are considered in the context of the individual's clinical picture, medications, kidney function, and vitamin D status.
