Abstract
Objective To study the value of COBIO XS urinary sediment analyzer (COBIO XS analyzer) for assisted diagnosis of urinary tract infection (UTI) .Methods A total of 349 specimens of midstream urine were ex-amined for leukocyte and bacteria counts by COBIO XS analyzer after bacterial culture was conducted .According to the results of bacterial culture ,Receiver operating characteristic (ROC) curve was drawn with SPSS18 .0 software . The cut-off value of leukocyte and bacteria counts for diagnosis of UTI were identified ,and its sensitivity ,specificity , positive/negative predictive value ,false positive/false negative rate and accuracy were calculated .Results The posi-tive rate of urine culture was 20 .65% .Taking 136 bacteria/microliter and 13 .5 leukocytes/microliter as cut-off value of bacterial number and leukocyte number ,the specificities were 94 .1% and 66 .9% ,the sensitivities were both 88 .6% ,the negative predictive values were 96 .93% and 95 .74% ,false negative rates were both 2 .36% ,and the Kappa value was 0 .923 .Conclusion COBIO XS analyzer could be adopted to conduct simple ,rapid and reliable urine screening tests ,and its bacterial counts might be a better index for diagnosing UTI .关键词
