title: [Usefulness of two tests for rapid diagnosis of urinary infections in pregnancy].
abstract: Sixty pregnant women with symptoms of UTI, who assisted to the Emergency Room of the INPer, were submitted to urine culture and rapid urine tests for the detection of nitrites and leukocytes with the "Multistix 10 SG" (R) stripes. A control group was integrated of 20 pregnant women without symptoms of UTI submitted to the same methodology. In the first group, 34 urine cultures were reported as negative, 9 were as contaminated and 17 were positive. The sensitivity and specificity of the nitrite test was 94%. For the leukocyte test, the sensitivity was 64% and the specificity was 100%. In the control group, 13 urine cultures were negative, two were contaminated and five were positive. In this group, the sensitivity of the nitrite test was 100% and the specificity was 92%; while the sensitivity of the leukocyte test was 40% and the specificity was 100%.
