The expected degree of intraoperative PTH reduction, which guides surgical decision-making, determines the sensitivity and specificity of this test. While stricter criteria may enhance diagnostic accuracy, an optimal threshold has not been conclusively established. The aim of this study was to identify the PTH reduction threshold that provides the highest sensitivity and specificity for achieving biochemical cure.<\/jats:p>\n          <\/jats:sec>\n          <jats:sec>\n            <jats:title>Patients and methods<\/jats:title>\n            <jats:p>A retrospective analysis was conducted on 141 patients who underwent parathyroidectomy for primary hyperparathyroidism, focusing on the intraoperative drop in PTH and surgical success.
