The purpose of this study is to determine whether measurement of parathyroid hormone (PTH) concentrations in the early postoperative period accurately predicts patients at risk of developing hypocalcaemia.\n                  <\/jats:p>\n                  <jats:p>\n                    <jats:bold>Methods:\u2003<\/jats:bold>\n                    A prospective cohort study of patients undergoing TT was carried out. PTH concentrations were measured preoperatively and at 4 and 23\u2003h postoperatively. Serum calcium concentration was measured preoperatively and twice daily for 48\u2003h after surgery.\n                  <\/jats:p>\n                  <jats:p>\n                    <jats:bold>Results:\u2003<\/jats:bold>\n                    One hundred patients undergoing TT were recruited into the study in the period June 2004 to July 2005. Benign multinodular goitre was the most common indication for surgery (77%). The incidence of temporary hypocalcaemia (Ca\u2003&lt;\u20032.0\u2003mmol\/L) was 18%. The mean PTH concentration at 4\u2003h after surgery was 22.3\u2003ng\/L and was not significantly different from the 23\u2010h concentration of 23.2\u2003ng\/L (\n                    <jats:italic>P<\/jats:italic>\n                    \u2003=\u20030.18). A PTH concentration of \u22643\u2003ng\/L measured at 4\u2003h after surgery had a sensitivity, specificity and likelihood ratio of 0.71, 0.94 and 11.3, respectively, for predicting postoperative hypocalcaemia. The accuracy of a single PTH concentration at 4\u2003h was good for predicting hypocalcaemia (area under receiver\u2013operator characteristic curve 0.90; confidence interval 0.81\u20130.96). There was no significant difference in accuracy between the 4\u2010 and 24\u2010h PTH concentrations (\n                    <jats:italic>P<\/jats:italic>\n                    \u2003=\u20030.14).\n                  <\/jats:p>\n                  <jats:p>\n                    <jats:bold>Conclusions:\u2003<\/jats:bold>\n                    A single measurement of PTH concentration in the early postoperative period after TT reliably predicts patients who are likely to develop hypocalcaemia.
