摘要
目的应用正常人新鲜全血对多台血液分析仪进行比对,使血液分析仪各参数之间具有可比性。方法用Sysmex XT-1800i血液分析仪作为规范操作检测系统,对正常人新鲜全血进行定值,分别对2台SysmexKX-21和1台KX-21N血液分析仪进行比对。结果3台血液分析仪比对前偏倚超过允许范围的参数占53.3%(8/15),比对后偏倚超过允许范围的参数占13.3%(2/15)。结论比对后各参数之间可比性增加,同时提高了检测结果的一致性。
Objective To calibrate hematology analyzers with fresh blood to make their parameters comparable. Methods Fresh blood assigned by hematology analyzer Sysmex XT-1800i as normative measurement system was used to calibrate two Sysmex KX-21 analyzers and one KX-21N analyzer respectively. Results In the parameters calibrated for hematology analyzers, there was about 53.3% （8/15） over allowable bias before calibration but 13.3% （2/15） after calibration with fresh blood. Conclusions Parameters of hematology analyzers calibrated with fresh blood are comparable and coincident.
