“…Moreover, intraoperative PTH (ioPTH) monitoring provides a more precise profile of the PTH level (51). Von Beek et al (52) found that there was a strong correlation between ioPTH and early postoperative PTH levels, indicating that ioPTH was a potentially useful index for predicting surgical effectiveness. In patients with functioning allografts, ioPTH levels 10 min and 20 min after resection of the parathyroid glands were equivalent to 2.6 times and 2.3 times the post-operative PTH levels, respectively, and were considered to possibly fall within the expected target range (52).…”
