Order Parathyroid Hormone (PTH) Test | Lab TestThe parathyroid hormone (PTH) test measures the amount of PTH in the blood. PTH is produced by the parathyroid glands, four small glands located behind the thyroid gland in the neck. This hormone is central to calcium regulation: it raises blood calcium by prompting the release of calcium from bone, increasing calcium absorption in the intestines, and reducing calcium loss through the kidneys. Because PTH and calcium influence each other in a feedback loop, the PTH test is usually interpreted alongside a calcium measurement rather than on its own.
About Parathyroid Hormone (PTH) Test | Lab Test in Apache Junction
The PTH test is a blood test used to evaluate parathyroid function and calcium balance.
PTH is secreted in response to low blood calcium. When calcium levels fall, the parathyroid glands release more PTH; when calcium levels rise, PTH secretion decreases. Disruption of this feedback loop can indicate parathyroid disease or another condition affecting calcium homeostasis.
Doctors order a PTH test to investigate abnormal calcium levels, to help distinguish between parathyroid disorders and other causes of calcium imbalance, and to monitor people with known parathyroid or kidney conditions. It is frequently paired with tests for calcium, vitamin D, phosphorus, and magnesium, since these factors all interact with PTH regulation.
Results are interpreted in the context of the calcium level. A high PTH with a high calcium suggests overactive parathyroid glands, while a high PTH with a low calcium can point to a secondary cause such as kidney disease or vitamin D deficiency. A low PTH with a high calcium suggests a different mechanism. Because results depend on the clinical picture, the PTH value is best reviewed by a clinician alongside other laboratory findings and the person's history.
