How accurate are UTI test strips?
UTI test strips are fairly accurate for detecting infection markers, but false negatives and false positives can occur, so clinical judgement is still needed.
Detailed Medical Explanation
Test strips check for nitrites, leukocytes, and sometimes blood. They can miss some infections, particularly in older adults and certain bacteria. Lab confirmation is recommended if symptoms persist. NHS: NHS: UTI diagnosis.

Our clinicians use strips as a first step but rely on symptoms and culture for diagnosis: UTI Clinic.
