INTACT PARATHYROID HORMONE (PTH)

The intact parathyroid hormone (PTH) test measures the level of PTH, a hormone produced by the parathyroid glands, in the blood. PTH regulates calcium levels in the blood and bones. This test is used to diagnose and monitor conditions affecting calcium metabolism, such as hyperparathyroidism, hypoparathyroidism, and chronic kidney disease. Elevated PTH levels can indicate primary or secondary hyperparathyroidism, while low levels suggest hypoparathyroidism. The PTH test provides valuable information for assessing calcium balance, diagnosing underlying conditions, and guiding treatment decisions. It helps ensure optimal bone health and prevent complications associated with abnormal calcium and PTH levels.
