Parathyroid Hormone (PTH)

Parathyroid hormone (PTH), a polypeptide containing 84 amino acids, is secreted by the chief cells of the parathyroid glands. It has a molecular weight of 9.4 kDa. PTH should be measured in the investigation of unexplained hypercalcaemia or hypocalcaemia. PTH should always be interpreted in light of the serum adjusted calcium concentration and the patient’s renal function.
