摘　　要：目的利用爱威AVE-766尿有形成分分析仪与镜检对尿液中主要参数(红细胞、白细胞、管形、上皮细胞)的结果进行比较,验证爱威AVE-766尿有形成分分析仪的有效性。方法选取1 000例住院患者和门诊患者的晨尿标本,由Urisys 2400尿干化学分析仪进行干化学检测,UF-1000i尿有形成分分析仪、AVE-766尿有形成分分析仪、Olympus显微镜三者进行尿液有形成分检测,然后计算AVE-766检测结果的真阳性率、假阳性率、真阴性率、假阴性率以及符合率。结果 (1)AVE-766的红细胞真阳性率为100%,真阴性率为99.7%,假阳性率为0.3%,假阴性率为0%;白细胞真阳性率为100%,真阴性率为99.9%,假阳性率为0.1%,假阴性率为0%;管形真阳性率为100%,真阴性率为100%,假阳性率为0%,假阴性率为0%;上皮细胞真阳性率为100%,真阴性率为100%,假阳性率为0%,假阴性率为0%。(2)AVE-766与镜检符合率为99.7%。结论本室采用AVE-766尿有形成分分析仪对原有复检规则进行验证,误诊率、漏诊率都较低,与人工显微镜镜检结果符合率高,具有临床可操作性和有效性。Objective To compare the true positive rate, the true negative rate, the false positive rate, the false negative rate of the main parameters of the red blood cells （RBC）, the white blood cells （WBC）, the CAST, the epithelial cells （ES） in urine, with the re-examination rules for the results of urine routine test in this lab. Method Selecting 1 000 cases of inpatients and outpatients＇ morning urine samples; detecting by Urisys 2400 urine dry chemistry analyzer, examining the urine visible components with the UF-1000i urine visible components analyzer, urine AVE-766 tangible composition analyzer, Olympus microscopy; then calculating the true positive rate, false positive rate, true negative rate, false negative rate, and the coincidence rate of the results detected by AVE-766. Results （ 1 ） with AVE-766, the RBC＇ s true positive rate was 100%, and the true negative rate was 99.7%; the false positive rate was 0.3%, the false negative rate was 0%; WBC＇s true positive rate was 100%, and the true negative rate was 99.9%; the false positive rate was 0.1%, but the false negative rate was 0%; CAST＇s true positive rate was 100%, and the true negative rate was 100%; but the false positive rate was 0%, and the false negative rate was 0%; EC＇s true positive rate was 100%; the true negative rate was 100%; the false positive rate was 0%, and the false negative rate was 0%. （2）The coincidence rate for AVE-766 and microscopic examination was 99.7%. Conclusion After the lab adopted AVE-766 urine visible components analyzer experiment totest on the original rules of the re-examination, the rates of misdiagnosis and missed diagnosis were low, andits coincidence rate with manual microscopy results was high. Thus AVE-766 is clinically feasible and effective.
