The validity of urine examination for urinary tract infections in daily practice

For urinary tract infections (UTI), diagnostic testing appearsto be reliable and simple to per form. This particularly seemsto hold true for test strips. In studies the validity of severalurine tests proved to be high. These studies were, however,performed under optimal and standardized conditions. Their resultstherefore do not reflect daily practice. In this study the validityof urine tests for UTI is determined under daily practice conditions,without the use of a protocol. The results show a validity considerablylower than under optimal conditions. Specificity in particularwas lower, even for simple tests like the nitrite reaction.Under daily practice conditions, UTI can neither be confirmednor excluded sufficiently on the basis of the outcome of a urinarysediment or test strip.     

3种检测方法在女性尿路感染诊断中的应用比较

目的探讨H-500、UF-1000i、UF-100检测方法在女性尿路感染诊断中的应用,以增强女性尿路感染临床诊断的准确性和快速性。方法 300份女性疑似尿路感染患者的中段尿标本分别进行尿培养、H-500、UF-1000i、UF-100检测,比较各组检测所得结果。结果 300例样本中尿培养、H-500、UF-1000i、UF-100检测尿路感染真阳性率分别为100.0%、72.9%、80.0%、67.5%,真阴性率分别78.5%、62.7%、77.5%、70.0%,准确度分别为86.3%、66.3%、76.0%、68.7%。结论 UF-1000i辅助诊断女性尿路感染诊断的临床效能接近于尿培养,并具有快捷、价廉的应用优势,值得临床推广应用。
