Parathyroid Hormone: An Early Predictor of Postthyroidectomy Hypocalcemia

Abstract

A single PTH level of less than or equal to 8 pg/mL 1 hour postthyroidectomy is a strong predictor for the development of clinically significant hypocalcemia. Once validated, this test may serve to identify those who require more intensive monitoring, prompt early therapy in those deemed at risk, and enable confident early discharge in the majority of thyroidectomy patients.
