A new approach for perioperative parathyroid hormone (PTH) measurement to establish cure in patients with primary hyperparathyroidism.

Pre-incision PTH is not superior to preoperative PTH blood test and can be omitted without compromising the sensitivity of cure prediction. One blood sample 15 min after resection, along with the postoperative PTH value on the day after surgery, is sufficient to predict the surgical outcome bearing the cost of a very low reoperation rate.
