    Abstract

    Background: We aimed to validate a nomogram for diagnosing primary hyperparathyroidism (PHP), particularly when normocalcemic PHP and vitamin D (VitD25) deficiency coexist. Methods: The nomogram calculates maximal upper limit of normal PTH unique for each person by maxPTH = 120 - [6*calcium] - [*VitD25] + [*age]. PHP is suspected when serum PTH exceeds maxPTH. Normocalcemic PHP (NCPHP) was defined as always normal serum calcium (8.5-10.5 mg/dL) with PTH >60 pg/mL preoperatively and VitD25 deficiency as
