Objective To analyze the main analysis performance and function expansion of Mindray EH-2080B fully automatic urinary sediment analysis system made in China.Methods The main instrument detection projects,such as white blood cell(WBC),red blood cell(RBC) and endothelial cell (EC),were applied to analyze the equipment performance.The relative deviation was used to analyze the variance between different equipments,the positive (negative) rate was used to assess the instrument detection project compared with manual microscopy.The low power single view of the liquid filling static time period and visual persistence of low power and high power photographed conversion view instant were used to dynamically observe the living sperms and trichomonas vaginalis' messages by artificial browsing; the function extension of the instrument was observed accordingly.Results The main performance of the instrument detection projects was reasonable.The relative deviation of different equipments was ≤ 1/2 of total errors (TEa) provided by equipment production,which was consistent with the instrumental performance requirements.The instrument detection project comparison with manual microscopy results showed that WBC,RBC and fungi detections had a certain degree of false positive (negative) rate,but the comprehensive analysis coincidence rate of the overall clinical urine samples was more than 85％.The artificial browsing could be added to capture the dynamic information or suspicious information of living sperms or/and trichomonas vaginalis.Conclusions Mindray EH-2080B fully automatic urinary sediment analysis system made in China meet the requirements of the laboratories in clinical diagnosis.The results of the system and manual microcopy show a correlation; the artificial browsing may capture dynamic information or suspicious dynamic information of living sperms and/or trichomonas vaginal; according to the results of dynamic observation by using the equipment combined with RBC quantitative analysis results,the diagnosis of trichomonas infection can be made.
