Abstract Background We sought to evaluate the relationship between the preoperative core‐laboratory parathyroid hormone (CL‐PTH) level and the baseline intraoperative PTH (IOPTH) level and assess the impact of any differences on clinical decision making in consecutive surgical patients with primary hyperparathyroidism undergoing parathyroidectomy. Methods The CL‐PTH and baseline IOPTH levels were compared. The influence of relying on either the CL‐PTH or baseline PTH levels for intraoperative decision making was determined. Results Data were available for 316 patients. Baseline IOPTH measurements were usually higher than the CL‐PTH (247 patients; 78.2%) measurements, with a mean difference of 68.2 pg/mL ( P < .001). Using the CL‐PTH as a surrogate for the baseline parathyroid hormone (PTH) would have prolonged the operation in 23 patients (7.3%). Conclusion Baseline point‐of‐care IOPTH levels were higher than the preoperative CL‐PTH levels in >75% of patients undergoing parathyroidectomy. Using the CL‐PTH in lieu of an IOPTH baseline value would prolong the operation in some patients.
