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. 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, and its measurement helps clinicians evaluate parathyroid function and calcium balance.
About Parathyroid Hormone (PTH) Test | Lab Test in Placentia
PTH testing is primarily used to investigate disorders of calcium homeostasis and parathyroid gland function.
The parathyroid glands release PTH in response to low blood calcium levels. PTH then acts on the kidneys, bones, and intestines to raise calcium concentrations. When this feedback loop is disrupted, PTH levels can become abnormally high or low, producing distinct patterns that help identify the underlying condition.
A PTH test is commonly ordered alongside calcium and sometimes phosphorus or vitamin D measurements. Results are interpreted together because the relationship between PTH and calcium is more informative than either value alone. For example, elevated PTH with high calcium suggests overactive parathyroid glands, while elevated PTH with low calcium can point to a different cause such as kidney disease or vitamin D deficiency.
The test is used in the evaluation of suspected hyperparathyroidism and hypoparathyroidism, in monitoring chronic kidney disease, and in investigating unexplained abnormalities in calcium levels. It may also be used during parathyroid surgery to confirm that abnormal tissue has been removed.
