干化学法与尿沉渣联合用于尿常规检验作用的探讨

Effect of combined methods of dry chemistry method and urinary sediment in detecting routine urine test

目的观察与探讨干化学法与尿沉渣联合用于尿常规检验的临床效果,为临床尿常规检验方法提供参考依据。方法随机选取2014年5月至2015年5月间于该院进行尿常规检查的患者300例,随机分为3组,每组100例,分别采用干化学法、尿沉渣法及干化学法与尿沉渣联合检测,对3组患者进行尿常规检测,对比3组患者尿常规检测结果、误诊率、漏诊率等指标的差异,评价干化学法与尿沉渣联合检测的效果,对尿常规的检测方法提出参考意见。结果干化学法检测定量红细胞阳性率显著高于尿沉渣法,尿沉渣法测定白细胞阳性率显著高于干化学法,差异有统计学意义(P<0.05);干化学法与尿沉渣联合检测能使红细胞和白细胞阳性率显著提高,差异有统计学意义(P<0.05);干化学法与尿沉渣联合检测误诊率为4.0%,漏诊率为3.0%,总错误率为7.0%,总错误率显著高于单独采用干化学法或尿沉渣法,差异有统计学意义(P<0.05)。结论干化学法与尿沉渣联合检测方法能显著提高红细胞和白细胞阳性率,减少误诊率和漏诊率,使得检验结果出错的概率大大减少,推荐将其用于尿常规检查。

Objective To observe and discuss effect of combined methods of dry chemistry method and urinary sediment in detecting routine urine test the dry chemistry method associated with urinary sediment used in the clinical effect of urine routine test and to provide reference for clinical detection of urine routine test.Methods A total of 300 patients were randomly selected from May 2014 to May 2015 in our hospital for urine routine test and were divided into three groups,each group had 100 cases.By dry chemistry test,urine sediment method and dry chemistry method combined with urinary sediment examination method,routine urine tests of three groups were conducted and the results as well as misdiagnosis rate and missed diagnosis rate were compared between the three groups,so as to evaluate the effect of combined detection.Results The positive rate of red blood cell of patients in dry chemical group was significantly higher than that of the patients in urinary sediment group.While the positive rate of white blood cell of patients in urinary sediment group was significantly higher than that of the patients in dry chemical group,the difference was statistically significant（P〈0.05）.And the positive rate of both red blood rate and white blood rate in the dry chemistry method associated with urinary sediment group was much higher than that of other the two groups,the difference was statistically significant（P〈0.05）.The misdiagnosis rate and the missed diagnosis rate of the dry chemistry method combined with urinary sediment group were 4.0% and 3.0%,respectively.And the total false rate was significantly higher than that of the other groups,the difference was statistically significant（P〈0.05）.Conclusion Dry chemistry method combined with urinary sediment can obviously improve the positive rate of red blood cell and white blood cell,it could also reduce misdiagnosis rate and the missed diagnosis rate,which can be used in clinic.
