尿干化学法与尿沉渣镜检联合检测尿白细胞、红细胞的临床意义

The clinical significance of urine drug chemical and urine sediment microscope examination combined detecting urine white blood cell and red blood cell

目的通过尿液干化学法检测白细胞、红细胞。与尿沉渣人工镜检相比较，对干化学法产生的假阳性及假阴性结果原因进行探讨。方法收集本院随机新鲜尿液600例，分别进行干化学法检测和尿沉渣人工镜检其尿液中的白细胞、红细胞。结果干化学法白细胞检测结果的假阳性率为3．59％，假阴性率为16．2％，红细胞检测结果的假阳性率为13．3％，假阴性率为6．37％。结论干化学法检测尿红、白细胞有相当高假阳性率和假阴性率；进行尿、液分析时应按标准化的要求进行外观理学，化学，显微镜检查。

Objedive Through the urine drychemlcal method to detect white blood cells, the red blood cells, and urine dreg cys- tourethroscepy artificially compared ,dry flhemical method to produce false positives and false negafie result explores the eanse. Methods The data of 600 eases of our random flesh urine are dry chemical method to detect and urine dreg artificial cystourethroscopy are found in the urine of white blood cells, the red blood cells. Results dry chemical method of white blood cells the results of detection false positive rate was 3. 59%, the false negative rate is 16.2%, and the testing results of red blood ceils false positive rate was 13.3%, the false negative rate of 6. 37%. Conclusion dry chemical method to detect the urine red and white blood cells have very high rate of false positives and false negatives; in urine analysis should be according to the requirements of standardization appearanee/physical, chemical, examination under the microscope.
