We screened 691 asymptomatic prenatal patients by quantitative culture of clean voided urine specimens and one of three office screening devices to detect bacteriuria. The ability of each screening system to detect a single pathogenic organism in concentration equal to or greater than 100,000/ml was analyzed. Microstix-3 reagent strips had 87.5% accuracy, with the smallest number of false-positive results (6.7%). The Bacturcult system was correct in 75% of cases, but yielded 30% false-positive results. The Testuria system was least accurate (62.5%) and had the highest incidence of false-positive tests (71%).
我们通过对清洁中段尿标本进行定量培养以及使用三种门诊筛查设备之一，对691名无症状产前患者进行筛查，以检测菌尿症。分析了每个筛查系统检测浓度等于或大于100,000/ml的单一病原微生物的能力。Microstix-3试剂条的准确率为87.5%，假阳性结果数量最少（6.7%）。Bacturcult系统在75%的病例中检测正确，但假阳性结果率为30%。Testuria系统的准确率最低（62.5%），假阳性检测的发生率最高（71%）。
