In brief: UTI

Nitrite is a marker on the dipstick that can indicated a uti.
Many of the bacteria that cause a UTI create nitrite in the urinary tract and the specific reagent on the dipstick will show its presence.

Nitrites are produced by the reduction of dietary nitrates by gram negative bacteria. e.g., E.coli, Klebsiella, and Proteus, but not by gram-positive orgasms such as enterococcus.

In brief: Nitrites

Presence of nitrites in urine, as opposed to nitrates, is usually a sign of a urinary tract infection by gram negative bacteria- commonly E Coli.
Normal urine contains nitrates,however.
