Abstract

Platelate count is screening test to help establish the diagnosis. Results check up platelet influenced by several stages, namely the pre-analytic stage, the analytical stage, and the post-analytic stage. One of the pre-analytic stages is the postponement of the examination. Delaying this test can cause changes in the blood cells. Blood samples with the anticoagulant EDTA have a sample stability of 1 hour which should be checked immediately. Delaying the examination will cause a decrease in the number of platelets. The delay causes the platelets to continue to actively carry out metabolism which then causes the platelets to clot and experience swelling so that the platelets will break into smaller fragments. The purpose of this study was to determine the description of the platelet count in EDTA blood samples with a delay of 30 minutes at room temperature. This type of research is descriptive using quota sampling with a sample of 27 students of class 3A1 Study Program D-III National Medical Laboratory Technology STIKES. The platelet count was checked with a Mindray BC-2800 hematology analyzer. The research was conducted at the Budi Peni Clinical Laboratory. The time of the study was carried out in January-June 2021. The results showed that the average platelet count in venous blood samples without delay was 318,111 and the median value was 307.000, while the average platelet count for 30 minutes at room temperature was 316.250 and the median value of the platelet count results in venous blood samples is 304.000. The conclusion of this study is based on the average and median values of a decrease in platelet count with a delay of 30 minutes and without delay.
