Results: 114 cases were confirmed with UTI (95 %). The pH obtained was acidic in 84,2 % and basic in 15,8 % of the samples with PPV 78,95% and NPV 1,98 %. The results showed 26,7 % of nitrites with PPV 93,75 % and NPV 4,55 %; 93,3 % of leukocytes with PPV 99,11 % and NPV 62,5 % and 58,3 % presence of blood with PPV 94,29% and NPV 4 %. Presenting high efficacy, showing sensitivity of 97,37 % and specificity of 83,33 %. Conclusion: The efficacy of the test strips is high with a sensitivity of 97,37 % and specificity of 83,33 %.
