摘　　要：目的对UF-500i尿有形成分分析仪(UF-500i)、迪瑞H-500尿干化学分析仪(H-500)及尿沉渣镜检检测尿液成分的结果进行分析,建立显微镜复检规则。方法收集687份住院和门诊患者尿液标本,分别完成H-500检测、UF-500i检测及尿沉渣镜检,以尿沉渣镜检结果作为金标准。结果白细胞结果显示,H-500灵敏度为84.0%,UF-500i灵敏度为98.6%,H-500联合UF-500i灵敏度为100.0%;红细胞结果显示,H-500灵敏度为93.9%,UF-500i灵敏度为86.5%,H-500联合UF-500i灵敏度为97.8%;管型结果显示,UF-500i灵敏度为81.3%,H-500联合UF-500i灵敏度为100.0%;上皮细胞及结晶结果显示,UF-500i灵敏度均为100.0%。结论H-500、UF-500i各有其优缺点,将两种方法联合检测尿液成分,可降低漏检率,但不能替代尿沉渣镜检,需要参照相应的复检规则进行复检,以保证检测结果的准确性。Objective To analyze the results of the urine visible component analyzer (UF-500i) and the Dirui dry chemical analyzer (H-500) and urine sediment microscopic examination,and to establish the rules of microscopic re-examination. Methods A total of 687 urine samples from inpatient and outpatient patients were collected,and H-500 test,UF-500i test and examination were performed respectively.The results of microscopic examination were taken as the gold standard. Results White blood cell detection result showed that,the sensitive of H-500 was 84.0%,the sensitive of UF-500i was 98.6%,and the sensitive of H-500 combined with UF-500i was 100.0%.Red blood cell detection result showed that,the sensitivity of H-500 was 93.9 %,the sensitivity of UF-500i was 86.5%,and the sensitivity of H-500 combined with UF-500i was 97.8 %.Cast detection result showed that,the sensitivity of UF-500i and H-500 combined with UF-500i was 81.3% and 100.0 %,respectively.For detection of epithelial cells and crystallization,the sensitivity of UF-500i was 100.0 %. Conclusion H-500 and UF-500i have their own advantages and disadvantages.Combining the two methods to detect urine components can reduce the rate of missed detection,but it cannot replace the microscopic urine sediment microscopic examination.It is necessary to refer to the corresponding re-examination rules for re-inspection to ensure the accuracy of the test results.
