Improving Intraoperative Parathyroid Hormone Specimen Handling and Processing.

Surgeons request intraoperative parathyroid hormone (PTH) monitoring during parathyroidectomy procedures to confirm identification of abnormal gland tissue. Generally, a 50% decrease in the baseline PTH level indicates the abnormal tissue has been removed. A delay in collecting and processing PTH blood samples can complicate intraoperative decision making and prolong the procedure.
