THE WORTH OF TOTAL CALCIUM LEVELS ADJUSTED BY VARIOUS FORMULAE IN DIAGNOSIS OF HYPOCALCEMIA

Aim: The aim was to evaluate the diagnostic performance of the corrected calcium formulas in the diagnosis of hypocalcemia. 
Materials and Methods: Corrected calcium levels were calculated using the Modified Orrell, Orrell, Payne, Berry and James methods. Individuals were divided into groups according to albumin levels. In each of the hypoalbuminemia and normoalbuminemia groups, diagnostic performance values of measured serum total calcium, and corrected total calcium concentration in the diagnosis of hypocalcemia was calculated. The hypocalcemia was diagnosed by free calcium levels 
Results: 46.3% of the results were in the hypoalbuminemia group and 53.7% in the normoalbuminemia group. The test with the highest sensitivity in the hypoalbuminemia group was the measured total calcium test (80.3%). Sensitivity was
