both assays equally discriminated patients with surgically confirmed primary hyperparathyroidism from normal individuals , but the pth ( 1-84 ) irma also allowed a nearly absolute discrimination between normal subjects and patients with primary hypoparathyroidism ( undetectable serum pth in 18 of 21 cases ) and secondary hypoparathyroidism ( caused by hypercalcemia that was caused by a malignant tumor , pth 1.3 +/- 1.3 ng/l , n = 32 ) .
