Order Parathyroid Hormone (PTH) Test | Lab TestThe parathyroid hormone (PTH) test is a blood test that measures the amount of parathyroid hormone circulating in the bloodstream. This hormone, produced by the four small parathyroid glands located behind the thyroid, is the body's primary regulator of calcium balance. Because PTH and calcium work in a tightly controlled feedback loop, measuring PTH alongside calcium gives clinicians a clearer picture of how the parathyroid glands are functioning and whether calcium homeostasis is being maintained.
About Parathyroid Hormone (PTH) Test | Lab Test in Lancaster
The PTH test is most often ordered when a calcium abnormality is detected or suspected, or when a clinician is evaluating parathyroid gland function.
Parathyroid hormone raises blood calcium by prompting the bones to release calcium, the kidneys to retain calcium, and the intestines to absorb more calcium from food. When calcium levels drift too low, PTH secretion rises; when calcium levels climb, PTH secretion normally falls. This inverse relationship is central to interpreting results.
An elevated PTH level alongside a high calcium level can point toward primary hyperparathyroidism, a condition in which one or more parathyroid glands produce too much hormone. A low PTH level with a high calcium level may suggest a different cause, such as a malignancy or another process unrelated to the parathyroid glands.
PTH is also monitored in people with chronic kidney disease, since the kidneys play a key role in calcium and phosphate regulation and parathyroid function can become disrupted. Results are typically interpreted together with calcium, phosphate, vitamin D, and sometimes kidney function markers rather than in isolation.
