Application of EXCEL in Evaluating the Precision Performance of XE-2100 Automatic Blood Cell Analyzer / 国际检验医学杂志

ABSTRACT

Objective To evaluation the precision performance of XE-2100 Automatic Blood Cell Analyzer using EXCEL Mi-crosoft with reference to CLSI EP15-A3 .Methods According to CLSI EP15-A3 ,high level and low level (BIO-RAD company) of quality control materials were measured using XE-2100 Automatic Blood Cell Analyzer ,and analyzed by one-factor analysis of vari-ance of EXCEL 2003 and equation editor .The within-run coefficient of variation and within-laboratory coefficient of variation were calculated and compared with national industry standards and manufacturer statement .Results For high and low level of quality control materials ,the within-run coefficient of variation and within-laboratory coefficient of variation of white blood cell ,red blood cell ,hemoglobin and platelet were less than national industry standards and manufacturer statement .Conclusion The precision ver-ification scheme of CLSI EP15-A3 with EXCEL Microsoft has a relatively good maneuverability and statistical performance ,which could be used in verification of the precision performance of quantitative testing items in clinical laboratories .
