Experiences with the Rapid Calcium Infusion Test as a Criterion for Primary Hyperparathyroidism

A parathyroid suppression test, recently described in the literature, employing rapid calcium infusion test and a subsequent study of phosphorus excretion has been evaluated in 19 subjects with surgically proven parathyroid adenoma and 18 subjects who were apparently normoparathyroid. Statistical analysis of the data acquired indicates that the rapid calcium infusion test is of certain value as a diagnostic tool and a complement to more conventional methods used in the diagnosis of primary hyperparathyroidism.
