An Indication Of Urinary Tract Infection. Veterinarians usually screen dog and cat urine sample using a paper strip impregnated at different points with chemicals that change color when particular compounds are present in your petâs urine. One of those compounds the test looks for is nitrite. Nitrite is produced by certain bacteria. When the test is done correctly and your petâs urine contains any nitrite, it is quite likely that it has a bacterial urinary tract infection (UTI) - even when no bacteria were seen. Urine that sits too long at room temperature can give a false-positive due to bacterial contamination and growth while it sat.
