【摘要】目的 对尿液潜血检验中不同检验方法的应用价值进行剖析，为今后的临床检验工作提供有价值的参考信息。方法 选择2014 年1月～2015年12月，在我院留取尿液标本的患者190例作为研究对象，分别采用分析仪法和镜检法对尿液标本中潜血情况进行检测，对两种检测方法的检测结果进行对比分析。结果 统计发现，镜检阳性率较尿液分析仪低。结论 尿液分析仪法对尿液标本中潜血进行检验的工作效率高于镜检法，但是准确性相对于镜检法略低，两种检验方法联合应用，可提高临床检验准确性，减少误诊 的发生。

Objective To explore the application value of different urine occult blood testing methods，in an attempt to provide valuable reference for further clinical laboratory practice. Methods 190 patients from whom urine specimens were retained in our hospital from January 2014 to December 2015 were selected as the subjects. Occult blood in urine specimen was tested separately by using a urine analyzer and by microscopic examination，and comparative analysis was performed on the test results obtained with the two test methods. Results Statistical analysis showed that microscopic examination resulted in lower positive detection rate than did the urine analyzer. Conclusion While urine analyzer has higher efficiency than microscopic examination for testing occult blood in urine specimen，it has slightly lower accuracy than microscopic examination. Combination of the two test methods could therefore improve accuracy of clinical testing，thus reducing the incidence of misdiagnosis.

尿液潜血是由于红细胞数量减少引起的一种泌尿系统问题。临床对尿液进行检验的过程中，尿液潜血为一项必检项目，一般患者的身体有炎症、肾功能出血问题、结石或者尿路感染等都会造成尿液潜血。当前，尿液潜血检验的方法以尿液显微镜检验，据临床研究与实践证实［1］两种检验方法的优势各异，尿液显微镜检验法虽然检测的准确性较高，但检验成本也较高，而且方法比较复杂，占用人力交多，而尿液分析仪法具有检测时间短，方法比较简单，经济实惠的优点，所以大多以尿液分析仪检验为主［2］。尿液分析仪法。本次研究中，对我院收治的接受尿常规检查的190例患者的尿液标本采取不同方法进行了尿液潜血检验，并对检验结果进行了对比分析，结果汇报如下。……
