This test measures a substance called parathyroid hormone (PTH) in your blood. PTH is made by four tiny parathyroid glands in your neck. PTH circulates in your blood and is needed to regulate the level of calcium in your blood.
Primary hyperparathyroidism (HPT) is the most common cause of elevated parathyroid hormone (PTH) and calcium levels. Approximately 85% of cases are found to be caused by an isolated parathyroid adenoma, 15% by diffuse parathyroid hyperplasia, and less than 1% by parathyroid carcinoma.eedback inhibition of parathyroid hormone (PTH) release occurs primarily by direct effect of calcium at the level of the parathyroid gland. Although not well elucidated, 1,25-(OH) 2 D3 appears to exert a mild inhibitory effect on the parathyroid gland as well.
