Use

Parathyroid hormone (PTH) measurement is crucial for evaluating parathyroid gland function, primarily in conditions like hypercalcemia or hypocalcemia. The test aids in diagnosing primary or secondary hyperparathyroidism, as well as hypoparathyroidism. PTH levels, in conjunction with calcium and phosphate levels, help in assessing bone turnover rates and calcium homeostasis. Normocalcemic patients can have varying PTH levels based on their vitamin D status. This test is particularly useful for patients suspected to have parathyroid gland disorders or those with vitamin D insufficiency or resistance.
