The prescription of calcemia dosing is very frequently used to check the existence or not of both hypocalcemia or hypercalcemia. This study has been realized in order to identify the patients ratio having true hypocalcemia after comparing the total unadjusted calcemia and the total adjusted calcemia. Results show that during the study period 329 files were kept. The patients average age is 42 20, and the sex-ratio is 0.7.
122 cases (37.3%) of hypocalcemia and 9 cases (2.7%) of unadjusted hypercalcemia were found. Among the 131 cases of dyscalcemia, 58 patients (44.3%) presented hypoalbuminemia. Only 29 cases (51.8%) of real hypocalcemia presented a hypoalbuminemia. Only 29 cases of real hypocalcemia are put in evidence after being readjusted. The total calcemia dosing still stays the most available setting for the calcemia assessment. It is essential to make an adjustment of the albuminemia function when confirming a real hypocalcemia.
