目的：通过对尿液分析仪检测尿潜血反应和镜检红细胞的结果进行分析比较，探讨尿液潜血干化学分析结果的临床使用价值。方法选取我院门诊患者留取的尿液120份，分别使用尿液分析仪检验和镜检RBC，观察分析两种红细胞检验的检验效果，记录相关数据，进行统计学分析。结果尿液分析仪潜血检测的敏感度为91．23％，假阳性率为9．11％，假阴性率为10．12％；本研究检验的120例标本中，尿液分析仪测定为阳性的74例标本，同时用显微镜检查观察到红细胞的有59例，无红细胞的15例；而通过尿液分析仪测的为阴性的有46例，同时显微镜观察有红细胞的7例，无红细胞的39例。表明在临床检验尿液潜血的检验中使用尿液分析仪联合镜检检验对比单用镜检效果明显（P＜0．05），具有统计学意义。结论显微镜检测和尿液分析仪检测都会因为各种主客观因素的影响而出现一定的误差，但是它们的误差影响因素并不相同，因此在临床检测中，可以将两种检测方式结合使用，以便为患者的身体健康和生活质量提供更多的保障。","purpose The urine analyzer for detecting the urinary occult blood and microscopic analysis of red blood cellanalysis and comparison of the results of urine occult blood,dry chemical analysis results of clinical use value.Method Select 120 urine specimens from the out-patient clinic of our hospital,were used to test and microscopic examination of urine analyzer RBC,observation and analysis of two red celltest results,record relevant data,statistical analysis.Result Occult blood of urine analyzer detection sensitivity is 91.23%,false positive rate 9.11%,falsenegativeratewas10.12%;inthisstudy,120samplesofurineanalyzerexamination,74caseswerepositive,andexaminedmicroscopicalyobservedinredbloodcelsof59cases, 15 cases without red blood cells and the urine;analyzer for negative in 46 cases,and 7 cases of microscopic observation of red blood cells,red blood cells of 39 patients with non.That contrast test using urine analyzer combined examination in clinical urine occult blood test in single microscopic efect is obvious (P <0.05),with statistical significance.Conclusion Microscopic exami-nation and urine analyzer detection wil be because of various subjective and objective factors and appear a certain error,but the error factors are not the same,so in the clinical detection,can be used in combination with two detection methods,in order to provide more protection for the patient's health and quality of life.
