摘要
目的 探讨分析尿常规分析中出现的假阴性结果的原因及其改进措施。方法 选取自2012年1～3月在青田县人民医院住院患者送检的新鲜晨尿标本1 080例,分别采用干化学法和沉渣镜检法进行检测,观察对比两种方法的检测结果。结果 干化学法检测713例白细胞、748例红细胞呈阴性,沉渣镜检法检测692例白细胞、723例红细胞呈阴性;两种方法检测红细胞与白细胞出现的假阴性率分别为2.95%、3.34%,差异无统计学意义（χ2=0.900、1.330,均P〉0.05）。结论 尿常规分析应结合尿液分析仪干化学法与人工镜检法,从而提高检测结果的精确度与准确性,排除干扰因素,避免漏检、误检。
Objective To explore the reasons of false-negative results in urine analysis and improvement measures.Methods Fresh morning urine specimen of 1 080 cases from January 2012 to March 2012 in our hospital were selected,and they were determined by dry chemical and sediment microscopic examination, then the results were compared between the two methods.Results 713 cases of white blood cells and 748 cases of red blood cells showed negative results by dry chemical method,while 692 cases of white blood cells and 723 cases of red blood cells showed negative results by sediment microscopic examination;The false negative rate of red blood cells and white blood cells by two methods were 2.95%,3.34%,the test results of the two methods showed no significant differences（χ2=0.900,1.330,all P〉0.05）.Conclusion The urine analysis should combine with dry chemical method and artificial microscopic urine analysis to improve the precision and accuracy of the test results,and to eliminate interference factors for avoiding undetected false detection.
