UTI: Bacteria in urine may convert the non-ionic endogenous nitrates enzymatically to nitrites and when detected may suggest presence of uti. The most commonly detected bacteria responsible for this are gram-negative bacilli, but other organisms may also do this. Because of the large numbers of false negative and positive findings this is not a particularly effective diagnostic test.
