Order Parathyroid Hormone (PTH) Test | Lab TestThe parathyroid hormone (PTH) test is a blood test that measures the amount of PTH circulating in the bloodstream. PTH is produced by the parathyroid glands, four small glands located behind the thyroid gland in the neck, and it plays a central role in regulating calcium and phosphorus balance. Because PTH interacts closely with calcium, vitamin D, and the kidneys, measuring PTH is often part of a broader evaluation of mineral metabolism and bone health.
About Parathyroid Hormone (PTH) Test | Lab Test in Westminster
This test is used to help diagnose parathyroid disease and other conditions that involve calcium homeostasis.
PTH is the primary hormone responsible for keeping blood calcium within a narrow range. When calcium levels fall, the parathyroid glands release more PTH, which signals the bones to release calcium, the kidneys to retain calcium, and the intestines to absorb more calcium through vitamin D activation. When calcium levels rise, PTH secretion normally decreases.
An abnormal PTH result can indicate an overactive or underactive parathyroid gland. Primary hyperparathyroidism, for example, typically produces a high PTH level alongside a high calcium level, while hypoparathyroidism produces a low PTH level with low calcium. PTH testing is also used to investigate chronic kidney disease, vitamin D deficiency, and certain bone disorders.
Because PTH results are interpreted alongside calcium and sometimes phosphorus, vitamin D, or kidney function markers, the test is rarely evaluated in isolation. Results can be affected by medications, recent calcium intake, and other clinical factors, so the ordering clinician reviews the full picture rather than a single number.
