Abstract
Objective To evaluate the precision of the automatic coagulation analyzer CA7000.Methods The precision of prothrombin time(PT),activated partial thromboplastin time(APTT),thrombin time(TT) and fibrinogen(FIB) examined by automatic coagulation analyzer CA7000 were evaluated by NCCLS EP5-A2 document.Results For the four items(PT,APTT,TT,FIB),the within-run precision coefficients of variation were 0.54%-1.51%,0.64%-1.61%,2.87%,1.68%;the between-run precision coefficients of variation were 0.73%-3.27%,1.85%-2.06%,0%,1.98%;the between-day precision coefficients of variation were 0.98%-1.82%,0.56%-1.55%,1.94%,1.61%;the total precision coefficients of variation were 2.40%-3.63%,2.11%-2.90%,3.31%,3.06%.Conclusion The precision of PT,APTT,TT,FIB examined by automatic coagulation analyzer CA7000 can meet the requirements of clinical trials.
