Accuracy of PTH assay and corrected calcium in early prediction of hypoparathyroidism after thyroid surgery.

Objective: To evaluate the accuracy of the intraoperative parathyroid hormone (ioPTH) and 6-hour PTH (6hPTH) assay in predicting transient hypoparathyroidism after thyroidectomy.

Study Design: A nonrandomized prospective study was conducted on patients undergoing thyroid surgery.
