Useful For

Parathyroid hormone (PTH), which is produced by the parathyroid glands, is cleared from the blood stream very quickly. Within ten minutes of removing all hyperactive parathyroid tissue, the PTH levels fall rapidly. By testing PTH levels before removing hyperactive parathyroid glands, and then again after removal of abnormal gland the surgeon can determine if there are additional hyperfunctioning glands present.
