Evaluation of Analytic Performance of CA-1500 Automatic Coagulometor
Objective To evaluate the analytical performance characteritics of CA-1500 automatic coagulometor.Methods According to the National Committee for Clinical Laboratory Standards(NCCLS) EP5-A document,evaluate the within-run and Day-today precision of PT,APTT,TT,Fib,FⅧ: C,AT-Ⅲ and D-dimer on CA-1500 Automatic Coagulometor.Using quality control materials determinating the accuracy of the above tests.According to NCCLS EP6-P document,the linear range of Fib,FⅧ: C,AT-Ⅲ and D-dimer was analyzed.The low limited detection,carryover and the antijamming capability were evaluated.Results The within-run precision of PT,APTT,TT,Fib,FⅧ: C,AT-Ⅲ and D-dimer was lower than 1/4 allowable total error(TEa),while the between-day precision was lower than 1/3 TEa.The accuracy satisfied the laboratory requirement.Detecting of Fib,FⅧ: C,AT-Ⅲ and D-dimer has good linearity.The low limited detection,carryover and antijamming capability can meet the laboratory requirement.Conclusions The analytical performance characteristics of CA-1500 automatic coagulometor satisfy the laboratory performance goals.It can be used to analyze the patients' samples.
