摘　　要：目的分析AVE-763B全自动尿沉渣分析仪白细胞(WBC)假阳性检测结果的原因。方法对分析仪检测的WBC阳性标本进行显微镜复检。结果 740例阳性标本中,224例疑似假阳性,假阳性率为30.2%(224/740),其中145例可直接在分析仪编辑屏幕上重新正确分类,假阳性率减至10.7%(79/740)。结论造成WBC检测假阳性结果的因素较多。应增强识别假阳性图像的能力,同时结合显微镜复检,以进一步提高分析仪检测结果的准确性。Objective To analyze the reasons causing false positive results of white blood cells （WBC） detected by AVE‐763B automatic urine analyzer .Methods WBC positive samples ,detected by AVE‐763B automatic urine analyzer ,were re‐inspected by microscope .Results In the 740 positive samples ,224 cases were false positive ,the false‐positive rate was 30 .2% ,among which 145 cases could be correctly classified by using image analysis ,and the false‐positive rate reduced to 10 .7% .Conclusion Many fac‐tors could cause false positive results .To improve the accuracy of AVE‐763B urine analyzer ,re‐inspect should be performed .
