Impact of vitamin D-related serum PTH reference values on the diagnosis of mild primary hyperparathyroidism, using bivariate calcium/PTH reference regions
Clinical Endocrinology, 05/01/2012
Fillee C et al. – For a given specificity, primary hyperparathyroidism diagnostic parathyroid hormone thresholds were lower and sensitivities higher using receiver operating characteristic (ROC) curves, derived from 25(OH)D replete vs deplete controls. The 25(OH)D status does not affect the efficiency of primary hyperparathyroidism diagnosis, using bivariate PTH/calcium reference density ellipses.
