Abstract: Objective： To investigate the detection of urine sediment in patients by three methods. Methods：Urine analyzer， dry chemistry analyzer and microscope were used to analyze the visible components in 1 000 urine samples from a secondary first-class hospital in Kunming， and the test results and diagnostic coincidence rate were compared. Results： Among 1 000 urine samples， the detection rate of microscopic examination for white blood cells， red blood cells， bacteria， crystals， epithelial cells and fungi was high， the detection rate of urine analyzer for casts was high， and the dry chemistry analyzer could detect nitrite and protein that could not be detected by the above two methods. The combined test of red blood cells had the highest diagnostic coincidence rate， while the combined test of crystals， casts and epithelial cells had the lowest diagnostic coincidence rate. Conclusion： Both urine analyzer and microscopic examination are effective methods for urine examination， which have important diagnostic value. Dry chemistry analyzer can make up for the shortcomings of the above two methods to some extent. The three methods should be combined in clinical urine test to provide more reliable test results for clinical use.
