The Prothrombin time(P.T) test and activated partial thromboplastin time(APTT) test are commonly used for screening coagulation disorders and monitoring of anticoagulant therapy. We compared day to day reproducibility and normal range and coefficient of correlation of Fibrintimer and Electra-800 in PT. APTT. The results are : 1. Day-to-day reproducibility of PT and APTT expressed C.V. are 4.02%, 6.23% in Fibrintimer and 2.26%, 4.37% in Electra-800, which show good day to day reproducibility(P > 0.05). 2. The normal range of PT are 9.7 sec~ 13.3 sec in Fibrintimer and 10.1 ~ 13.3 sec, in ElectraBOO. The normal range of APTT are 26.8 sec ~34.2 sec in Fibrintimer and 25.3 sec~33. 5 sec in Electra-·800. 3. A coefficient of correlation of PT & APTT is 0.99 and 0.91 respectively between the Fibrintimer & Electra-800 which show high degree of correlation.
