摘要:
目的探讨尿微量清蛋白(mALB)的五种非线性校准方法的差异与特征,并确定其最合适校准曲线。方法分别采用对数函数(Logit-log3P,Logit-log4P,Logit-log5P)、样条函数(Spline)及多元折线函数(Line-Graph)五种校准方法对mALB进行校准,同时检测卫生部临床检验中心5个批号的室间质评物质,记录相关校准参数并对检测结果进行测量偏倚分析。结果五种校准方法的测量偏倚与平均秩次由小到大排序分别为Line-Graph(9.6%,7.5),Logit-log5P(12.0%,9.5),Spline(11.7%,11.8),Logit-log4P(13.2%,15.4),Logit-log3P(18.8%,20.8);五种校准方法测量偏倚差异有统计学意义(χ2=10.208,P<0.05)。结论多元折线函数(Line-Graph)校准方法测量偏倚与平均秩次最小,为mALB的最合适的校准曲线。
Abstract:
ObjectiveTo investigate the differences and characteristics of the five nonlinear calibration methods so that ascertain the most suitable calibration curve of Urine Microalbumin.MethodsRespectively adopted the five nonlinear calibration methods of the logarithmic functions (Logit-log3P,Logit-log4P,Logit-log5P),the spline function(Spline) and the multi line function (Line-Graph) to calibrate the mALB and testing the quality control materials of EQA simultaneously.Recorded the calibration parameter of mALB and analysed the measurement bias of test results.ResultsAccording to the measurement bias and the mean rank of the calibration methods,the results of the research were Line-Graph(9.6%,7.5),Logit-log5P (12.0%,9.5),Spline (11.7%,11.8),Logit-log4P (13.2%,15.4) and Logit-log3P (18.8%,20.8).There were significant differences in the measurement bias of the five calibration methods (χ2=10.208,P<0.05).ConclusionThe multi line function (Line-Graph) was the most suitable calibration curve of Urine Microalbumin for its minimum measurement bias and mean rank.
