Among 101 nursing home residents with suspected urinary tract infection (UTI), we determined the negative predictive value of dipstick testing for leukocyte esterase and nitrite to be 100% (95% confidence interval, 74%-100%), compared with laboratory evidence of UTI (greater than 10 white blood cells/mm(3) on urinalysis and greater than 100,000 colony forming units/mL on urine culture). Nursing home dipstick testing effectively excluded the possibility of UTI.
在101名疑似患有尿路感染（UTI）的疗养院居民中，我们确定，与UTI的实验室证据（尿液分析中白细胞超过10个/mm³，尿培养中菌落形成单位超过100,000/mL）相比，尿液试纸检测白细胞酯酶和亚硝酸盐的阴性预测值为100%（95%置信区间，74%-100%）。疗养院的尿液试纸检测有效地排除了UTI的可能性。
