摘要
目的探讨尿沉渣镜检和尿常规干化学法在尿常规检验中的应用价值。方法选取2018年1月~2020年1月沈阳市第五人民医院收治的340例尿液样本作为研究对象,接受尿沉渣镜检、尿常规干化学法以及两种方法联合检测。比较三种检测方法的白细胞、尿蛋白、红细胞阳性率。结果尿沉渣镜检与尿常规干化学法方法的敏感性、特异性及准确性比较,差异无统计学意义(P>0.05);两种方法联合检测的敏感性、特异性、准确性高于单独一种检测方法,差异有统计学意义(P<0.05)。尿干化学检测的定量白细胞阳性率低于尿沉渣镜检,定量红细胞阳性率高于尿沉渣镜检的定量红细胞阳性率,差异有统计学意义(P<0.05);联合检测的定量白细胞阳性率和定量红细胞阳性率均高于尿干化学检测和尿沉渣镜检测,差异有统计学意义(P<0.05)。结论尿沉渣检法、尿常规干化学法均具有临床检验价值,而联合应用两种检测方法,更有力于降低漏诊、误诊概率,提高临床检验水平。
Objective To explore the value of urinary sediment microscopic examination and urine routine dry chemical method in routine urine examination.Methods A total of 340 urine samples admitted to Shenyang Fifth People′s Hospital from January 2018 to January 2020 were selected as the research subjects,microscopic examination of urinary sediment,routine dry chemistry and the combination of the two methods were performed.The positive rates of white blood cell,urine protein and red blood cell of the three detection methods were compared.Results There were no significant differences in the sensitivity,specificity and accuracy between microscopic examination of urinary sediment and routine dry chemical method(P>0.05).The sensitivity,specificity and accuracy of the combined detection of the two methods were higher than those of the single method,and the differences were statistically significant(P<0.05).The positive rate of quantitative leukocyte in urine dry chemistry test was lower than that in urine sediment microscopic examination,and the positive rate of quantitative erythrocyte in urine sediment microscopic examination was higher than that in urine sediment microscopic examination,and the differences were statistically significant(P<0.05).Quantitative leukocyte positive rate and quantitative erythrocyte positive rate of combined detection were higher than those of urine routine dry chemical method and urinary sediment microscopic examination,the differences were statistically significant(P<0.05).Conclusion Both urine sediment test and routine dry chemical urine test have clinical testing value,and the combined application of the two detection methods is more effective in reducing the probability of missed diagnosis and misdiagnosis,and improving the level of clinical testing.
