摘　　要：目的对两种尿液干化学分析仪的稳定性和检测结果一致性比较。方法使用AX-4280和Hipee S2两台尿检仪分别测定625例尿液常规标本,比较检测结果的阳性率和符合率。随机选取200例样本,通过尿沉渣显微镜复核潜血红细胞(RBC)和白细胞(WBC)两项检测结果。结果两台仪器室内质控符合率均达100%。临床样本测试结果显示pH值差异百分率均值<10%,比重(SG)差异百分率均值<1%,其余8项指标一般符合率都大于90%。AX-4280和Hipee S2的RBC测试结果与尿沉渣显微镜计数结果的符合率分别达81.0%、84.0%,WBC结果符合率分别达72.0%和77.5%。结论 AX-4280和Hipee S2检测结果一致性良好,但尿液干化学分析仪在RBC和WBC两项检测时,还应结合显微镜尿沉渣计数的结果进行临床判断。Objective To compare the stability and consistency of AIKELAI AX-4280 and FRUITECH Hipee S2 urine dry chemistry analyzers.Methods A total of 625 cases of urine specimens were detected on AX-4280 and Hipee S2 urine analyzers in parallel.The detection results were compared by the positive rates and coincidence rates.A total of 200 samples were randomly selected for reviewing RBC and WBC by urinary sediment microscopy.Results The indoor quality control coincidence rate of two analyzers reached 100%.The mean difference percentage of pH value between the two analyzers was lower than 10%,the mean difference percentage of specific gravity（SG）was lower than 1%,and the general consistency rates of other 8 projects were higher than 90%.The consistency rates of AX-4280 and Hipee S2 were 81.0% and 84.0% with urine sediment microscopy on RBC,and 72.0% and 77.5% on WBC respectively.Conclusion The results of AX-4280 and Hipee S2 are in good agreement,but the results of RBC and WBC should also be combined with microscopic urine sediment count results for clinical judgment.
