Nitrites in urine
Nitrites in the urine form when certain bacteria convert natural nitrates into nitrites. Their presence is a fairly specific sign of a bacterial urinary tract infection.
This marker is reported as negative or positive on the strip; the app rates it qualitatively, not against a numeric range.
Why it matters
ECLM: positive indicates a bacterial urinary tract infection.
If it’s low
Negative nitrites do not completely rule out infection (some bacteria do not produce them, or the urine was not in the bladder long enough).
If it’s high
Positive nitrites indicate a bacterial urinary tract infection — especially with symptoms and leukocytes in the urine.
What to do
Positive nitrites with symptoms → likely infection, consultation. For assessment a morning, concentrated sample is best (nitrites need time in the bladder).
