Background: Calcium is a fundamental mineral in the human body, crucial for various physiological processes, especially in bones and muscles. Accurate measurement of calcium levels is essential for diagnosing and monitoring numerous medical conditions. In this study, we aimed to compare the performance of seven calcium measuring kits utilizing two different methodologies, Arsenazo-III and orthoCresolphthalein-complexone (o-CPC), using ELITROL-I human serumbased control material.
