Abstract

Laboratory services play a crucial role in supporting medical diagnosis. One such test is the erythrocyte sedimentation rate (ESR) test, which typically uses 3.8% sodium citrate as an anticoagulant to prevent blood clotting. This study aims to analyze the comparison of blood sample volumes on the accuracy of ESR testing using the Westergren method. The research method used is an experimental study, collecting data from 30 blood samples from patients divided into several groups based on blood volume (600 µL and 800 µL). The results showed that larger blood samples (800 µL) provided more accurate and consistent ESR results compared to smaller sample volumes (600 µL). In conclusion, blood sample volume affects the accuracy of ESR testing using the Westergren method. Further research is needed to validate these findings and consider other factors that may influence ESR test results
