摘要
目的对Stago-CT和CA1500两种全自动凝血分析仪进行相关性分析和偏倚评估。方法根据EP9-A2文件的要求,分别在法国Stago-CT、日本Sysmex-CA1500凝血仪上检测凝血常规试验(PT、APTT、INR、FIB、TT、DD),其结果用于相关性分析和偏倚评估。结果 PT、APTT、INR、FIB、TT、DD项目的r2分别是0.996 9、0.969 1、0.967 7、0.955 8、0.972 6、0.949 6;PT、APTT、INR、FIB、TT、DD项目的预期偏倚分别是2.9、0.88、5.22、1.16、3.48、20.3。结论 PT、APTT、INR、FIB、TT项目两仪器相关性好(r2>0.95),DD项目两仪器相关性稍差(r2=0.949 6);PT、APTT、INR、FIB、TT项目的预期偏倚均在美国临床实验室CLIA′88要求的1/3偏倚内,DD项目的预期偏倚稍超出可接受范围。
Objective To evaluate the relationship and bias of the Stago-CT and CA1500 automatic coagulation analyzer.Methods The relationship and bias of PT,APTT,INR,FIB,TT,DD examined by the Stago-CT and CA1500 automatic coagulation analyzer by using NCCLS EP9-A2.Results For the six items（PT,APTT,INR,FIB,TT,DD）the r^2 were 〉0.996 9,0.969 1,0.967 7,0.955 8,0.972 6,0.949 6,respectively,and the bias were 2.9,0.88,5.22,1.16,3.48,20.3.Conclusion The five items（PT,APTT,INR,FIB,TT）at a good relationship（r^20.95）by the Stago-CT and CA1500 automatic coagulation analyzer except for the DD（r^2=0.949 6）;The bias of the five items（PT,APTT,INR,FIB,TT）were within in the United States of demanding that a third of the clinical laboratory of CLIA 88′bias,except for the DD.
