Efek Homogenisasi Spesimen Darah Metode Inversi Terhadap Nilai Hematokrit

Laboratory examination consists of three stages, namely pre-analytical, analytical, and post-analytic. The biggest error occurred in the pre-analytical stage, which was around 61%. Homogenization including stage is process mixing blood anticoagulants are included stage. has two ways manual automatic. Inadequate homogenization can cause clots or rupture erythrocytes/lysis shrinkage erythrocytes, leading to a falsely low hematocrit value. study aimed find out analyze differences values by homogenizing inversion method 2, 4, 10 times. This type research observational analytic. carried June - August 2021 at Clinical Muhammadiyah University Palangkaraya. sample consisted 9 EDTA from people according inclusion criteria. All samples were examined for using Hematology Analyzer Sysmex XP-300. results showed that average value 2 times 38.40%, 4 38.78%, 39.14%. conclusion this there no significant effect technique on (p=0.584 > 0.05).
