Yоu аre wоrking with а pаtient whоse doctor has ordered a urinalysis, a urine test that includes a reaction to detect if nitrite is present in the urine. Nitrate is naturally present in the urine of healthy individuals since it is consumed in the diet, being especially present in vegetables, but nitrite should not be. If this test comes back positive, it indicates a urinary tract infection (UTI). What specifically does this test indicate about the pathogen, i.e., why does it test for nitrite?
