We compared the effectiveness of different methods of rapid diagnosis in the detection of asymptomatic bacteriuria in 74 females during the first trimester of pregnancy. The sensitivity, specificity and negative predictive value for the visual reading of nitrites, leukocyte sterase, bacteriuria and leukocyturia in the sediment and bacteria in Gram stain were 77%, 22%, 33%, 22% and 88%, 98%, 85%, 82%, 91% and 86%, and 97%, 89%, 90% and 90%, with and accuracy of 96%, 77%, 76%, 82% and 86%, respectively. The combination of visual readings of nitrites and Gram stain showed a sensitivity and negative predictive value of 100%. We conclude that if the reading of the reactive strip is negative, the likelihood of a positive culture is very small, and it is minimal when combined with Gram stain.
我们比较了不同快速诊断方法在检测74名孕早期女性无症状菌尿中的有效性。对亚硝酸盐、白细胞酯酶、尿沉渣中的菌尿和白细胞尿以及革兰氏染色中的细菌进行肉眼观察的敏感性、特异性和阴性预测值分别为77%、22%、33%、22%，88%、98%、85%、82%、91%和86%，以及97%、89%、90%和90%，准确率分别为96%、77%、76%、82%和86%。亚硝酸盐肉眼观察结果与革兰氏染色结果相结合，显示敏感性和阴性预测值均为100%。我们得出结论，如果反应试纸条读数为阴性，培养结果为阳性的可能性非常小，而与革兰氏染色结合时可能性最小。
