The method of stem chemistry is simple and fast, but it will be affected by some factors, resulting in false positive and false positive results of red blood cells and white blood cells. On the other hand, microscope examination is not only complicated but also prone to human errors. In order to improve the efficiency and accuracy of urine determination, this paper compared the results of red blood cells and white blood cells in stem chemistry and urine microscopy, in order to explore whether stem chemistry can completely replace microscopy to detect red blood cells and white blood cells in urine. In this paper, 310 urine samples were detected by dry chemistry and microscopy respectively, and the results of two methods were analyzed. The results showed that in 310 urine samples, 116 were positive in dry chemistry, 40 were positive in microscopic examination, the positive rate was 34.5%, 193 were negative in dry chemistry, 192 were negative in microscopic examination, the coincidence rate was 99.5%, 98 were positive in dry white blood cells, 75 were positive in microscopic examination, 23 were negative in microscopic examination. The positive control rate of the two methods was 76.5%, 212 cases were leukocyte negative and 195 cases were microscope negative. The results showed that the red blood cells with positive stem chemistry and the white blood cells with positive stem chemistry should be examined under the microscope.
