In the clinical laboratory, conditions are often found that cause the examination cannot be carried out immediately after specimen collection so that it must be delayed for an unpredictable period of time. The use of plasma with the anticoagulant heparin does not require waiting time, so it will speed up the completion of the examination and reduce the occurrence of hemolysis. Nowadays hospitals and commercial laboratories are switching to using heparin plasma in separator gels for testing. This research is a pre-experimental research design. The sample used was plasma from 15 respondents. The sample was plasma divided into 3 Heparin tubes. The first vacutainer tube was immediately centrifuged, while the second was delayed for 5 hours and the third was delayed for 10 hours. The results showed that there was a significant difference from the mean sodium concentration that had been examined. The average sodium concentration that was immediately centrifuged was 137.11 mmol / L, while those who were delayed for 5 hours obtained an average of 142.28 mmol / L and those who were delayed for 10 hours were obtained an average of 149.48 mmol / L. The conclusion is that the delay in centrifugation will affect sodium levels.
