FUS-200全自动尿液分析系统在筛检尿路感染中的应用

摘要

Objective To investigate the application value of FUS-200 automatic urine analysis system(FUS-200)in the rapid screening of urinary tract infection.Methods 268 cases of urine specimens were detected by FUS-200 and conventional bacterial culture,and the results were comparatively analyzed.According to the results of bacterial culture as standard control,the sensitivity and specificity of bacterial quantitative count for screening urinary tract infection of FUS-200 were evaluated.Results The results of FUS-200 quantitative bacterial counts and conventional bacterial culture were detected and comparative analyzed,the sensitivity was 51.7%,the specificity was 88.9%,the positive predictive value was 57.4%,and the negative predictive value was 86.4%.Conclusion The method of FUS-200 screening urinary tract infection is s faster than conventional urine bacteria culture,and especially it manifests higher predictability for the negative result.It can provid the reference information wether there is a bacterial infection for the clinical work,but can not replace the conventional bacterial culture.%目的：探讨FUS-200全自动尿液分析系统（简称FUS-200）对快速筛检尿路感染的应用价值。方法以FUS-200和常规细菌培养法对268例尿标本分别进行检测并比较分析，以细菌培养结果为标准对照，评估FUS-200细菌定量计数对筛检尿路感染的灵敏度和特异性等。结果采用FUS-200对尿液细菌计数与常规细菌培养法检测结果比较分析，灵敏度为51．7％；特异性为88．9％，阳性预测值为57．4％，阴性预测值为86．4％。结论采用FUS-200筛检尿路感染，比常规尿液细菌培养更快速，尤其对阴性结果具有高度的预见性，可给临床提供是否有细菌感染的参考信息，但不可代替常规细菌培养。
