UKURAN KALSIUM ION DALAM SERUM TOTAL KALSIUM (CALSIUM TOTAL) MENGGUNAKAN BERBAGAI ALAT SWA-ANALISIS (AUTO ANALYSER)

Calcium measurements in the emergency laboratory use several instruments. Nova pHox Plus (group A) measures ionized calcium whereas Beckman Synchron CX5 (group B) and Cobas Integra (group C) measures total calcium. Comparison of the results from the three auto analysers has never been performed. To compare calcium results using three auto analyzers are Nova pHox Plus, Beckman Synchron CX5, and Cobas Integra. Samples consisting of whole blood were examined by Nova pHox Plus auto analyser and serum samples were examined using Beckman Synchron CX5 and Cobas Integra auto analyser. This study has been carried out on 21 individuals. Statistical analysis was performed using T-test and Pearson correlation coefficient. The level of significance was determined as 0.05. Results of the three auto analysers did not show significant correlation (P > 0.05). There were not significant correlation between Nova pHox Plus and Beckman CX5, Cobas Integra.
