摘    要:目的通过对本室Hitachi7170和Olympus AU1000两种生化检测系统的测定结果进行方法比对和偏倚评估,探讨不同生化检测系统间检测结果是否具有可比性。方法参照美国临床实验室标准化委员会(NC—CLS)的EP9-A2文件要求,以Hitachi7170为参比系统,Olympus AU1000为试验系统,检测40例患者血清的16个生化项目,计算相关系数、直线回归方程和不同医学决定水平处的相对偏差(SE%),并以美国临床实验室改进修正案能力验证(CLIA’88)允许总误差的1/2为标准,评价检测结果是否具有可比性。结果两种不同生化检测系统的检测结果相关性良好,各项目的相关系数大于0.975,差异有统计学意义(P〈0.01);除了清蛋白及尿酸各有一个医学决定水平处的SE%〉1/2CLIA’88,超出临床可接受范围外,其余项目的SE%均在临床可接受范围。结论当同一实验室内同一检测项目存在两种以上分析系统时,应进行方法比对和偏倚评估,以实现检测结果的可比性。

关 键 词:全自动生化分析仪  偏差评估  方法比对  医学决定水平

Abstract:Objective The comparability of serum results of different biochemical detecting system were studied through the method of comparison and bias estimation between Hitachi 7170 and Olympus AU1000.Methods According to the profile NCCLS EP9-A2,two different biochemical testing system,Hitachi 7170(comparison method) and Olympus AU1000(laboratory method),were used respectively to test 16 serological items to obtain the correlation coefficient and the linear equation,and the system bias % at the level of medical de...
Keywords:automatic biochemical analyzer  bias estimation  method comparison  the level of medical decision
