A urine nitrite test can indirectly detect certain bacteria. A positive result raises the possibility of a urinary tract infection.
What does this result or symptom mean?
Not all bacteria produce nitrites, so a negative result does not exclude infection. Symptoms, white cells, pregnancy status and sometimes urine culture determine the next steps. Bacteria without symptoms do not always require antibiotics.
Practical steps and preparation
Keep track of burning, frequency, fever or flank pain. Avoid starting leftover antibiotics and tell your clinician if pregnant or at higher risk.
When should you seek prompt care?
Fever with flank pain, vomiting, pregnancy with urinary symptoms or marked illness needs prompt care.
Frequently asked question
Can you have a UTI with negative nitrites?
Yes. The test has limitations and some bacteria do not produce nitrites.
Checklist before a clinical consultation
To make your appointment more useful, consider the following:
- Write down when the problem began and how it has changed.
- Bring a list of medicines, supplements and relevant previous test results.
- Prepare the questions you want to discuss.
