目的:通过对不同检测系统进行方法比对分析,探讨各系统之间检测丙氨酸氨基转移酶(ALT )、天冬氨酸氨基转移酶(AST)、总蛋白(TP)、白蛋白(ALB)和血糖(GLU)五个项目测定结果具可比性。方法:依据美国临床实验室与标准化委员会(NCCLS )的EP-A2有关文件,选择具有代表性的五个检测项目,首先研究各个系统的精密度,再通过系统间的比对进行准确度、相关性分析。以日立(Hitachi )7600-110全自动生化分析仪作目标检测系统1,日立7170作实验检测系统2,强生(Vitros-)350全自动干式生化分析仪作为比对仪实验检测系统3,每天选取2份新鲜混合血清,分别在三台仪器上测定该五个项目,共测20次取其均值并记录结果。结果:五个项目在三个检测系统的日内精密度均小于CLIA’88(美国临床实验室修正法规)允许总误差(TEa)的1/4,日间精密度小于CLIA’88 TEa的1/3;各个试验系统与目标系统比对的相关系数 r>0.975,P>0.5,系统误差(SE%)小于CLIA’88规定的Ea的1/2。结论:三个检测系统的检测项目结果准确可靠,相关性良好,临床可以接受。
目的:通過對不同檢測繫統進行方法比對分析,探討各繫統之間檢測丙氨痠氨基轉移酶(ALT )、天鼕氨痠氨基轉移酶(AST)、總蛋白(TP)、白蛋白(ALB)和血糖(GLU)五箇項目測定結果具可比性。方法:依據美國臨床實驗室與標準化委員會(NCCLS )的EP-A2有關文件,選擇具有代錶性的五箇檢測項目,首先研究各箇繫統的精密度,再通過繫統間的比對進行準確度、相關性分析。以日立(Hitachi )7600-110全自動生化分析儀作目標檢測繫統1,日立7170作實驗檢測繫統2,彊生(Vitros-)350全自動榦式生化分析儀作為比對儀實驗檢測繫統3,每天選取2份新鮮混閤血清,分彆在三檯儀器上測定該五箇項目,共測20次取其均值併記錄結果。結果:五箇項目在三箇檢測繫統的日內精密度均小于CLIA’88(美國臨床實驗室脩正法規)允許總誤差(TEa)的1/4,日間精密度小于CLIA’88 TEa的1/3;各箇試驗繫統與目標繫統比對的相關繫數 r>0.975,P>0.5,繫統誤差(SE%)小于CLIA’88規定的Ea的1/2。結論:三箇檢測繫統的檢測項目結果準確可靠,相關性良好,臨床可以接受。

Objective :To discuss the comparability of 5 tests (ALT ,AST ,TP ,ALB ,GLU ) results among different systems ,which are analyzed by the methods compared .Methods :According to EP9-A file of NCCLS ,5 representative i-tems (ALT ,AST ,TP ,ALB ,GLU)are explored their precision of various systems ,and are analyzed the relationship , such as the precision ,the accurate and the relation liner through the comparation with different systems .The auto-chemical analyzer of Hitachi 7600-110 is target system 1 ,Hitachi 7170 and Vitro 350 are detection systems 2 and detec-tion system 3 respectively .There are 2 fresh combination serums daily and selected to detect 5 items in 3 detection sys-tems ,and 20 results appeared to their averages and write down the values .Results :The precision of within a day 5 tests results in 3 detection systems are lower than that of the quarters of CLIA ’88 TEa ,and the results day and day are low-er than that of one-third of CLIA’88 TEa;the relation liners between target system and detection systems are higher 0.975 ,and the possibility are higher 0 .5 ,the system errors (SE% ) are lower then that of one-second of CLIA’88 TEa . Conclusion:The comparation results of 3 different systems are accurate and rely ,the relation liners are perfect accorded evolution of clinical acceptability .
