目的:尿干化学分析仪与尿沉渣联合应用于妊娠期妇女尿常规检验的观察研究.方法:选择在2019年1月～2020年6月期间于我院进行常规产检的妊娠期妇女病例资料中随机抽取50例患者的尿常规检验(尿干化学分析仪与尿沉渣)资料作为本次研究的观察组,再从门诊患者中选取50例与观察组同期的满足本次对照组研究标准(健康非孕期)的妇女资料,对两组资料的检验结果进行回顾性对比分析.结果:两组资料的检验结果进行回顾性对比分析后,尿干化学分析仪检测结果显示:白细胞(WBC)的假阳性率达到4.17％(1/24),假阴性率65.38“,”Objective:To observe the application of urine dry chemical analyzer combined with urinary sediment in routine urine examination of pregnant women.Methods:the case data of pregnant women who underwent routine prenatal examination in our hospital from January 2019 to June 2020 were selectedThe routine urine tes(t urine dry chemical analyzer and urinary sediment)data of 50 patients were selected as the observation group of this study,and then the data of 50 women who met the research criteria of the control group(healthy non pregnancy) in the same period as the observation group were selected from the outpatients,and the test results of the two groups were retrospectively compared and analyzed.Results:after the retrospective comparative analysis of the test results of the two groups,the urine dry chemical analyzer showed that the false positive rate of leukocyte(WBC)was 4.17％(1 / 24),and the false negative rate was 65.38％(17 / 26);The false positive rate of RBC was 6.98％(3 / 43)and the false negative rate was 14.29％(1 / 7).The results of urinary sediment test showed that the concentration of epithelial cells,urinary leukocytes and bacteria in the observation group were significantly higher than those in the control group.The above data were comparedretrospectively,and the differences were statistically significant(P ＜ 0.05).Conclusion:in the detection rate of urinary leukocytes and erythrocytes,the combined test of urinary dry chemical analyzer and urinary sediment is of great significance It has certain complementarity,which can avoid misdiagnosis and missed diagnosis to a certain extent in clinical examination.It can be used for early disease screening of pregnant women and has clinical application value;Compared with the test results of the control group,the test results of urinary sediment in the observation group wereThe concentration of epithelial cells,urine leukocytes and bacteria increased significantly to a certain extent,which can establish a routine reference range for this test in clinical testing.
