Popis: | OBJECTIVE The objective of the present study was to elucidate the parathyroid responsiveness by measurements of blood Ionized calcium and serum intact parathyrold hormone (PTH) concentrations, before and during trisodium citrate induced hypocalcaemia. PATIENTS AND CONTROLS Sixteen patients with primary hyperparathyroidism and 32 healthy volunteers. DESIGN Blood ionized calcium concentration was lowered by about 0.20 mmol/l and maintained at this level for 2 hours by blood ionized calcium controlled trisodium citrate infusion. MEASUREMENTS Serum PTH(1–84) was measured by an Immunoradiometric assay. RESULTS In patients and controls, baseline measurements of blood Ionized calcium were 1.39±0.07 vs 1.24±0.04 mmol/l (mean.SD) (P |
