[New diagnostic examinations in patients with urinary calculi, taking into consideration primary hyperparathyroidism].
The serum levels of total calcium and anorganic phosphate have been the leading parameters in the diagnosis of primary hyperparathyroidism. In addition to these, it is now possible to measure ionized calcium (Ca++) by an ion-selective electrode and parathormone (PTH) by C- and N-terminal radioimmunoassays (RIA). Whereas Ca++ determination and C-terminal PTH RIA represent a diagnostic progress, this can not be claimed for the N-terminal PTH RIA in peripheral venous blood especially in border-line cases.
