Evaluation of a standardized short-time calcium suppression test in healthy subjects: interest for the diagnosis of primary hyperparathyroidism

Abstract

The standardized short-time PTH suppression test appears reliable to differentiate healthy subjects from PHP whose serum PTH levels remain >14 and >23 ng/ml respectively at the end of loading and 3 h later. This well-tolerated and easily performed test could be used for the diagnosis of PHP in patients suspected for the disease despite the normality of some basal biological markers.
