Point-of-care rapid intraoperative parathyroid hormone assay of needle aspirates from parathyroid tissue: a substitute for frozen sections

Point-of-care IOPTH assay of needle aspirates is an accurate method of distinguishing parathyroid from nonparathyroid tissues. It is suggested that this would be particularly useful in instances where use of IOPTH is planned for assessment of a drop in serum PTH.
