Liao Ji-cheng. Department of Clinical Laboratory,the Sixth People's Hospital of Chengdu City,Chengdu 610051,China
Objective In the large and medium-sized hospital laboratories,it is usual to put many the same type of equipment into use. Before use,contrast test and bias evaluation ought to be carried out so as to determine whether the results of other instruments were in the allowable range compared with the reference method,and to calibrate into uniformity.Methods According to EP9-A file,Electrolyte K+,Na+ and Cl-were detected with four different instruments,and then the correlation and regression analysis was performed on the results,deviation among was calculated and revised.Results There were significant differences among in detective results of the same test items.Conclusion The comparability of the results should be analyzed when the same test items were detected with various instruments. The laboratory must use the same standard preparation for calibration to ensure the accuracy and uniformity of the results.
