RESUMO
Objective To compare the differences and comparability of the results of the Changsha AVE-764B urine sediment analyzer and the traditional artificial microscopy for detecting the urine sediment visible components .Methods The visible compo-nents in the same fresh urine were detected by the AVE-764B urine sediment analyzer and the artificial microscopy method .The negative and positive coincidence rate ,sensitivity ,specificity and Chi square test were adopted to conduct the statistical analysis on the test data .Results The Chi square value of WBC ,RBC ,Cast and crystal were 2 .274 7 ,1 .554 1 ,3 .817 5 and 0 .258 1 respective-ly(P>0 .05);the negative and positive coincidence rates of WBC ,RBC ,cast and crystal were 84% ,86% ,84% and 78 .5% respec-tively ;the specificities of WBC ,RBC ,cast and crystal were 80 .2% ,85 .9% ,85 .9% and 77 .2% respectively ;the sensitivities of WBC ,RBC ,Cast and crystal were 90 .9% ,86 .3 % ,70 .8% and 80 .2% respectively .Conclusion The Chi square test results showed no statistically significant differences in the detection results between the two kinds of detection method (P> 0 .05) .The recognition and classification of the visible components detected by the AVE-764B automatic urine visible component analyzer have the higher coincidence rate with those detected by the standard artificial microscopy ,this analyzer has high automation degree ,is easy and simple to operate ,standardizes the urine routine test and meets the clinical demand .
