干湿生化分析仪检测电解质的可比性研究.

Objective To discuss the comparability of electrolyte detection results by dry biochemical analyzer and traditional wet chemical analyzer.Methods The methodological comparison was carried out according to the Clinical and Laboratory Standards Institute（CLSI）EP9-A3document,the Roche Cobasc701automatic biochemical analyzer was selected as the reference system,and the Ortho VITROS 5600automatic biochemical analyzer was selected as the under-test system,and a total of 40clinical specimens were measured respectively by two systems（dry biochemical analyzer and traditional wet chemistry analyzer）.The generalized extreme studenization deviate（ESD）method was used to detect outliers,and bias and scatter plots were plotted to determine the characteristics of the data.The bias was preliminarily estimated by using the deviation diagram,and the regression equation was fitted and the deviation at the medical decision level was calculated.Results The outlier was no found by the ESD method.The results of the two systems were well correlated（R2≥0.95）,and the bias of each item was less than the acceptable standard.Conclusion There was no obvious difference between dry biochemical analyzer and traditional wet chemical analyzer in the results of electrolyte detection,which is comparable.
