【摘要】 目的  探讨全自动尿沉渣分析仪在尿管型检测中的应用。 方法  收集尿管型患者晨尿标本836份。所有标本均经尿干化学分析仪检测Pro≥1+或尿沉渣分析仪提示有管型。采用UF100全自动尿沉渣分析仪和显微镜检测管型，对比分析两者的检测结果。 结果  836份标本中，UF100全自动尿沉渣分析仪检测阳性者320例，占38.28%；显微镜检测阳性者195例，占23.33%。其中UF100全自动尿沉渣分析仪的假阳性率为26.52%，假阴性率为23.08%。UF100尿沉渣分析仪与显微镜检测管型的阳性结果比较，差异有统计学意义（P lt;0.01）。 结论  UF100全自动尿沉渣仪能快速筛检尿沉渣，但存在一定的假阴性，必须同时将其检测结果与尿干化学结果结合考虑以决定是否再进行显微镜检测，减少假阴性以防止漏检。
【Abstract】 Objective  To investigate the application of UF-100 full-auto urine sediment analyzer in detecting cylindruia. Methods  836 specimens with cylindruia were selected. All the specimens with Pro≥1+ were dectected by chemical dipstick or cylindruia by urine sediment analyzer. The cast were detected by urine sediment analyzer and microscope, and the results were compared. Results  Of 836 specimens, 320 positive samples(38.28%) were found by UF-100 while 195 (23.33%) were found by microscope. False positive rate and false negative rate of UF100 were 26.52% and 23.08%. Compared the results of urine sediment analyzer with microscope, the difference was statistically significant (P lt;0.01). Conclusions  UF100 can detect urinary cast quickly, but there is a little high false negative rate. So we should consider urine sample whether to be detected by microscope compared with results of UF100 and chemical dipstick.
