Abstract
Objective To evaluate the performance of one coagulation analyzer after maintenance.Methods The precision,linearity,and carry over were verified in turn according to EP5A2 and EP6-A2 of clinical and laboratory standards institute(CLSI).Results For the maintained coagulation analyzer,the normal and pathological values of relative intra-precision were 0.95％ and 0.65％ for prothrombin time (PT),0.57％ and 0.62％ for activated partial thromboplastin time (APTT),and 0.66％ and 1.08％ for fibrinogen(FIB),respectively.The normal and pathological values of relative total precision were 1.6％ and 2.04％ for prothrombin time (PT),2.12％ and 2.06％ for activated partial thromboplastin time(APTT),and 3.2％ and 3.42 ％ for fibrinogen(FIB),respectively.The intra-precision and total precision values on the normal value of thrombin time (TT) were 0.96％ and 2.73％.The linear regression equation of FIB was y=1.029x-0.1548,r2=0.9999.The carry over was 6.5％.Conclusions The precision,linearity,and carry over of the maintained coagulation analyzer meet the performance requirements of clinical laboratory.关键词
