Background: Examination of the hematology panel (hemogram) consists of leukocytes, erythrocytes, hemoglobin, hematocrit, erythrocyte index and platelets. Platelets are the smallest elements formed in the bone marrow and play an important role in the process of blood clotting. Examination of the platelet count aims to determine the number of platelets per microliter of blood. Almost all laboratories in hospitals have used a Hematology Analyzer because the examination is more practical and accurate. The specimens used were derived from venous blood with the addition of K2EDTA anticoagulant. Storage of inspection material needs to pay attention to sample stability.Examination of the platelet count can cause changes in the platelet count, and changes in the examination of the platelet index such as the average platelet volume (MPV), platelet distribution width (PDW), and thrombocytopenia (PCT). The purpose of this study was to analyze the effect of variations in temperature and storage time on the number of platelets and the platelet index examined at various temperatures using a hematology analyzer. The study covers the field of Hematology in October-November 2021. The research is analytical in nature with a quasi-experimental design. The research subjects were 30, the sampling technique was accidental sampling with primary data. The examination method uses the impedance method with the Hematology Analyzer tool. Data were analyzed using SPSS 22 version.
