Abstract
Objective:To evaluate the accuracy of the urine physical composition analyzer results through artificial microscopic examination for urine samples analyzed by Copal XS urine physical composition analyzer.Method:A total of 1500 fresh urine samples of hospital outpatients and inpatients since October 2013 were collected,and Copal XS urine physical composition analyzer was used to analyze urine sediment,and microscopic examination was used to compare the results at the same time.Result:In 1500 samples there were 46 samples with hematemesis,and RBC were full in field vision of the microscope,and RBC were not distinguished or distinguished parts in 36 cases,and RBC were distinguished as fungal in 40 cases.In pyuria samples,WBC were full in field vision of the microscope or not distinguished completely in 38 samples,and overlapping WBC were known as pathological type in 5 cases.Turbid urine was amorphous type uric acid salt by microscopy examination,and there were 68 samples with instrument misstatement tube type.The viscose silks were incorrectly reported as tube type by instrument in 165 samples,and fungus was incorrectly reported as RBC in 1 sample.When urine concentration of RBC and WBC were low,RBC and WBC were not detected by the microscope method,but the instrument analysis was often had mild increases and dry white fine chemistry leucocyte lipase and occult blood were positive.Conclusion:Copal XS urine physical composition analyzer has count accurate in RBC,WBC and epithelial cell with low concentration,and it has high sensitivity and is suitable for large specimens to screening,but the high concentration of RBC,WBC,and turbid specimens would count inaccurately,and RBC,yeast,viscose silk and tube type are difficult to distinguish,and its need microscope to make the right evaluation.关键词
