摘要
目的评估XE-2100全自动血液分析仪对异常白细胞报警的可信度。方法对105例XE-2100全自动血液分析仪有异常白细胞提示的标本及200例无异常细胞报警的标本进行手工推片、瑞氏染色镜检。结果XE-2100全自动血液分析仪对异常细胞报警的灵敏度为100%,特异性为85.1%,阳性预测值为66.7%,阴性预测值为100%。结论XE-2100全自动血液分析仪作为异常细胞的初筛工具,其灵敏度极高,仍不能完全代替手工镜检。
Objective To evaluate the reliability of white blood cell morphologic abnormalities warnings of system XE -2100 hematology analyzer. Method Manual stained differentiation was performed on 200 normal morphology samples and 105 abnormal morphology samples. Resuits The analyzer test showed that the sensitivity and the specificity were 100 % and 85.1% for abnormal morphology, with the positive predictive value of 66. 7 % and the negative predictive value of 100 %. Conclusions The system XE - 2100 hematology analyzer has good primary screening ability and higher sensitivity, but it cannot completely take place of manual microscopic examination.
