The accuracy of reagent strip testing for urinary tract infection (UTI) was assessed in 100 elderly patients (50 acute patients admitted to hospital and 50 attending the day hospital). Reagent strip sensitivities were: acute patients-urinary nitrite 83%, blood 67%, protein 72% and leucocytes 72%, and day hospital patients-urinary nitrite 90%, blood 65%, protein 30% and leucocytes 60%. Urinary nitrite specificities were 100% for both groups of patients. Only 28% of patients with a UTI had specific symptoms of the infection; pyrexia and a raised WBC also proved poor indicators. Urinary nitrite was thus the most accurate immediate indicator of UTI.
对100名老年患者（50名住院急性患者和50名日间医院就诊患者）进行了尿试纸检测尿路感染（UTI）的准确性评估。尿试纸的敏感度为：急性患者——尿亚硝酸盐83%、血液67%、蛋白质72%和白细胞72%；日间医院患者——尿亚硝酸盐90%、血液65%、蛋白质30%和白细胞60%。两组患者的尿亚硝酸盐特异性均为100%。只有28%的UTI患者有该感染的特定症状；发热和白细胞计数升高也被证明是较差的指标。因此，尿亚硝酸盐是UTI最准确的即时指标。
