Intraoperative Parathyroid Hormone (IOPTH)

Intraoperative Parathyroid Hormone

Intraoperative parathyroid hormone (IOPTH) monitoring is a relatively new test that we use at the New York Center for Advanced Parathyroid Surgery. With this new rapid test we measure the parathyroid hormone level in the bloodstream before we remove the parathyroid adenoma and after we remove the parathyroid adenoma. If the parathyroid hormone level drops to 50% or more of its initial value, then this confirms the biochemical cure of primary hyperparathyroidism. This very specialized tests is available at only a few medical centers.
