Caption: Urine testing. Urine test strip for urinary tract infection (UTI) screening. The pad has been fixed with a reagent which changes colour according to the amount of nitrites in the urine. Excessive amounts of nitrites may indicate that there is a UTI because this indicates the presence of bacteria. The test relies on the conversion of nitrate to nitrite by the action of Gram-negative bacteria in the urine.
