摘　　要：目的建立多台血液分析仪的结果比对方案,保证结果的一致性。方法5台Sysmex系列血液分析仪,采用CLSIEP9-A2指南进行每年一次的标准比对,采用10份新鲜血标本进行每月的常规比对。结果标准比对方案中5台血液分析仪检测WBC、RBC、HGB、HCT和PLT的预期偏倚95%的可信区间均落在医学决定水平处的可接受误差范围内。常规比对方案在2011年7月至12月的比对中有一台仪器的HCT在8月检测结果偏倚(%)超出1/2TEa(总允许误差)范围下限,经纠正,系统偏倚在1/2TEa范围内。结论两种比对方案相结合,可确保不同血液分析仪检验结果的准确性和一致性。Objective To make a comparison scheme and ensure the comparability of test results in different hematology analyzers in a laboratory.Methods Five different series of Sysmex hematology analyzers were made standard comparison once a year according to CLSI EP9-A2,and were made routine comparison by using 10 fresh blood samples once every month.Results The 95% confidence interval of predicted bias of the compared parameters were accepted in standard comparison method;the results of HCT detected with a instrument exceeded assigned range for one time.When the instrument was adjusted,the bias was in assigned range.Conclusion Standard comparison method combined with routine comparison method may improve quality control of complete blood count and ensure the accuracy and consistency of test results in different hematology analyzers.
