摘　　要：目的探讨UF-1000i全自动尿沉渣分析仪与DiaSys(R/S500)尿沉渣定量分析工作站在尿管型检测中的联合应用。方法分别用UF-1000i尿沉渣分析仪和DiaSys(R/S500)尿沉渣工作站检测3492份标本,对尿管型的检测结果进行比较分析。结果 3492份标本中UF-1000i尿沉渣分析仪检测管型阳性969例(27.75%),DiaSys(R/S500)尿沉渣定量分析工作站检测管型阳性157例(4.50%)。UF-1000i检测管型的灵敏度为91.08%,特异度为75.23%,假阳性率为24.77%,假阴性率为8.92%,阳性预测值为14.76%,阴性预测值为99.45%,将UF-1000i尿沉渣分析仪与DiaSys(R/S500)尿沉渣定量分析工作站检测管型的阳性结果进行比较,差异有统计学意义(P<0.01)。结论 UF-1000i全自动尿沉渣分析仪能快速筛检尿沉渣,但尿管型检测的假阳性较高,并且存在一定的假阴性。必须将UF-1000i全自动尿沉渣分析仪与DiaSys(R/S500)尿沉渣定量分析工作站联合使用,才能有效减少假阳性和假阴性结果,以防止错检和漏检,并且可使尿沉渣分析真正做到标准化、自动化。Objective To investigate the combination use of the UF-1000i automated urine analyzer（UF-1000i） and DiaSys urinary sediment quantitative analysis workstation（R/S500） in detecting urinary cast.Methods 3492 samples were tested for urine cast by both UF-1000i and R/S500,and results of them were compared.Results 969（27.75%） samples were positive of cast tested by UF-1000i in 3492 samples.Meanwhile,157（4.50%） samples were positive of cast tested by R/S500.Sensitivity,specificity,false positive rate,false negative rate,positive predictive value and negative predictive value of UF-1000i in detection of cast was 91.08%,75.23%,24.77%,8.92%,14.76% and 99.45%,respectively.The difference between positive results of UF-1000i and R/S500 was statistically significant（P〈0.01）.Conclusion UF-1000i automated urine analyzer can rapidly screen urine sediment,but had a higher false positive rate of cast,and there are some false negative samples.UF-1000i automated urine analyzer must be combined with the DiaSys（R/S500） urinary sediment quantitative analysis workstation to effectively reduce the false positive and false negative results and to prevent false and missing detection,and can also make the urine sediment analysis truly achieve standardization,automation.
