Urine Nitrite
Urine nitrite detects bacterial conversion of dietary nitrate to nitrite and indicates a urinary tract infection when positive. It is highly specific for infection with gram-negative organisms such as E. coli, but sensitivity is lower because not all bacteria produce nitrites and the urine needs time in the bladder for the reaction. Interpretation is paired with leukocyte esterase.

What is Urine Nitrite?
Urine nitrite detects bacterial conversion of dietary nitrate to nitrite and indicates a urinary tract infection when positive. It is highly specific for infection with gram-negative organisms such as E. coli, but sensitivity is lower because not all bacteria produce nitrites and the urine needs time in the bladder for the reaction. Interpretation is paired with leukocyte esterase.
Why It Matters
A positive result strongly suggests bacterial urinary tract infection, since certain bacteria convert nitrates to nitrites. However, a negative result doesn't rule out UTI, as not all bacteria produce nitrites.
