ABSTRACT Objective: UF-1000i combination of urine sediment analyzer (hereinafter referred to as UF-1000i), urine dry chemistry analyzer (hereinafter referred to as dry chemistry) and sediment microscopy (microscopic examination) the clinical value of urinary constituents. Methods: Random collection of our hospital, 1,600 patients were fresh urine samples were used to UF-1000i, dry chemistry and microscopic examination, and statistical analysis. Results: UF-1000i and dry chemistry test results were significant differences, P<0.05, by microscopic examination as the standard, UF-1000i positive rate of detection of red blood cells 11.6%, 4.88% false positive and false negative was 5.38%; testing positive rate of 13.1% white, 2.44% false positive and false negative is 2.19%, test tube The positive rate of 7.75%, 6.25% false positive, no false negative; testing positive rate of 10.88% epithelial cells, 1.69% false positive and false negative 4.56%. UF-1000i and dry joint detection and examination of chemical comparison: 678 cases of positive samples, UF-1000i -positive red blood cells in 5 cases, microscopic examination for the amorphous salt in 2 cases, fungi in 3 cases; dry chemical 36 cases of protein-positive, microscopy negative; 8 cases of dry chemical red-positive, microscopy negative. 922 cases of negative microscopy specimens were positive in 6 cases WBC (2-4/HP). Conclusion: Both UF-1000i or UF-1000i and dry chemistry are not substitute for examination combined detection, UF-1000i and dry chemical joint detection can play a complementary role in screening, only the effective integration of the three, can improve efficiency and achieve both The purpose of guarantee the accuracy of the results, reflecting its clinical application.
