Order Parathyroid Hormone (PTH) Test | Lab TestThe parathyroid hormone (PTH) test measures the amount of PTH circulating in the blood. PTH is a hormone produced by the four parathyroid glands, small structures located behind the thyroid gland in the neck. Its primary role is to regulate calcium levels in the blood and tissues. Because calcium is essential for nerve function, muscle contraction, and bone health, PTH testing is often ordered when calcium levels are abnormal or when a parathyroid disorder is suspected.
About Parathyroid Hormone (PTH) Test | Lab Test in Fallbrook
PTH testing is typically used alongside calcium measurements to evaluate parathyroid function and calcium homeostasis.
PTH acts on the bones, kidneys, and intestines to keep blood calcium within a narrow range. When calcium levels drop, the parathyroid glands release more PTH; when calcium levels rise, PTH secretion decreases. This feedback loop helps maintain stable calcium concentrations.
A PTH test is commonly ordered when a routine blood test shows an elevated or low calcium level. It may also be used to investigate symptoms such as fatigue, bone pain, kidney stones, or muscle weakness that can accompany parathyroid disease. In some cases, it helps monitor people with known parathyroid disorders or those undergoing treatment that affects calcium balance.
Results are interpreted together with calcium, vitamin D, and kidney function tests. An elevated PTH with high calcium may point to primary hyperparathyroidism, while a low PTH with low calcium can suggest hypoparathyroidism. Other conditions, including kidney disease and vitamin D deficiency, can also influence PTH levels. Because many factors affect the results, a physician reviews the full clinical picture before making a diagnosis.
