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. This hormone is central to calcium homeostasis, helping to regulate how much calcium is released from bone, absorbed by the intestines, and reabsorbed by the kidneys. Because PTH and calcium work in a tightly controlled feedback loop, measuring PTH alongside calcium can help clinicians evaluate parathyroid function and identify disorders that disrupt mineral balance.
About Parathyroid Hormone (PTH) Test | Lab Test in Roswell
The PTH test provides a direct measurement of parathyroid gland activity and is interpreted in the context of calcium levels.
Parathyroid hormone is secreted in response to low blood calcium. It raises calcium by stimulating bone resorption, increasing intestinal calcium absorption through activation of vitamin D, and reducing calcium loss in urine. When calcium rises, PTH secretion normally falls, creating a negative feedback loop that keeps calcium within a narrow range.
A PTH test is typically ordered when a person has abnormal calcium levels, symptoms that suggest parathyroid disease, or a known bone or kidney condition. Results are most informative when paired with a simultaneous calcium measurement, since the relationship between the two helps distinguish primary hyperparathyroidism, secondary hyperparathyroidism, and other causes of calcium imbalance.
PTH exists in several forms in the blood, including intact hormone and inactive fragments. Most clinical assays measure the intact molecule, which is the biologically active form. Because reference ranges vary by laboratory method, results should always be interpreted using the range provided by the performing lab and in consultation with a healthcare provider.
