  • UTI Tests: What They Are & What They Mean? | Uqora®

    Urinary tract infection test strips often consist of 2 tests: a nitrite test and a leukocyte test. The nitrite test is used because gram-negative bacteria, like E. coli, convert nitrates into nitrites in the urine. This process doesn’t happen naturally, so the presence of nitrites may indicate a bacterial infection.
