UF-500i尿沉渣分析仪与显微镜检查尿沉渣中管型的结果对比分析

目的比较UF-500i尿沉渣分析仪与尿沉渣显微镜检查两种方法对尿液中管型检测的敏感性及其影响因素。方法对1226例患者的尿液分别用UF-500i尿沉渣分析仪分析和显微镜检查尿沉渣中管型。结果 UF-500i尿沉渣分析仪检测尿中管型阳性率为12.9%,灵敏度为36.8%,特异度为95.2%,假阳性率3.6%,假阴性率16.0%,符合率80.4%,阳性预测值72.2%,阴性预测值81.6%;尿沉渣显微镜检查尿中管型阳性率为25.3%。结论 UF-500i尿沉渣分析仪检测尿中管型存在较多的假阴性和假阳性,联合应用显微镜检查尿沉渣可提高管型检测的准确率。

Compared UF-500i automated urinalysis analyzer with microscopy results of urine sediment in the cast

Objective To compare the sensitivity and its influencing factors of UF-500i automated urinalysis analyzer and urine sediment microscopic examination in urine casts.Methods 1226 cases of patients with UF-500i automated urinalysis analyzer were analyzed urine sediment and microscopic examination of urine sediment in the cast.Results UF-500i automated urinalysis analyzer,urine cast positive rate was 12.9%,36.8% sensitivity and specificity of 95.2%,false positive rate of 3.6% false negative rate of 16.0% compliance rate of 80.4%,positive predictive value of 72.2% negative predictive value 81.6% ;urine sediment microscopic examination of urine in the cast-positive rate was 25.3%.Conclusion UF-500i automated urinalysis analyzer,urine tube there are more false negative and false positive,the combination of microscopic examination of urine sediment can increase the accuracy of detection tube.
