Abstract


The role of electrolytes in the human body is very important. Almost all metabolic processes are affected by electrolytes. The accuracy
of examination results depend on the management in pre-analytical, analytical, and post-analytical processes. The management of
specimen is one of the essential factors in pre-analytical process that may influence the accuracy of laboratory results. This study has
purposed to observe the influence of time-interval variation at the examination of Na, K, and Cl serum concentration. A cross-sectional
study was conducted on 30 outpatient’s serum samples who visited the Clinical Pathology Laboratory of Dr. Wahidin Sudirohusodo
hospital in Makassar during July to August 2007. The Na, K, and Cl serum samples were examined immediately, 1 hour-delayed, and
2 hours-delayed. Data were analyzed using paired T test in SPSS version 11.5. In this study we found that there was no significant
difference for Na and Cl between immediate and delayed samples, similarly showed for K between immediate and 1 hour-delayed (p >
0.05). A significant different for K between immediate and 2 hours delayed, and between the first hour and the second hour delayed
samples (p < 0.05). From this study we could conclude that delayed samples more than 2 hours had no influence for Na and Cl
examination result. Delayed samples more than 2 hours for K had influence for the examination result.
