Comparative analysis of results between Sysmex UF-500i urine sediment analysis instrument and microscopy
Objective To compare the results form Sysmex UF-500i urine sediment analysis instrument and microscopy, and compare their coincidence rate and influence factor. Methods Leave,fetch clinic and ward 800 of patients at random,each urine adopted UF-500i urine sediment analysis instrument and microscopy to examine. Result 800 examine into urine,UF-500i measure erythrocyte positive 261 .microscopy law measure. It produces unusual to be 195, 74. 7% coincidence rate,false positive rate 25. 3% ,UF-500i measure leucocyte positive 202,microscopy law examine out unusual 194,coincidence rate was 96.0% .the false positive rate was 4. 0%. UF-500i measure transparent positive 573 of in charge ofing etc,microscopy law measure,it appears musual to be 510,89. O％coincidence rate,the false positive rate was 11.0% ;UF-500i measure pathology positive 524 of in charge ofing etc. Microscopy law measure,it appearred unusual to be 412,78. 6% coincidence rate,the false positive rate was 21. 4%. Conclusion The tangible composition is complicated in the urine, UF-500i can totally replace the microscopy to examine,a kind of means of sieving when just the sample in enormous quantities is analyzed, measure result to be getting positive to need examine to UF-500i with microscope again still,in order to improve accuracy to report to the result. Two kinds of methous unite application,can improve the accuracy of measuring the result,have higher clinical using value.
