I just finished my antibiotics yesterday for my uti. i have no symptoms. this morning i did an azo test. it showed positive for leu and neg for nit?

Infection cleared: most likely since you are now asymptomatic and the urine dip was negative for nitrites. Leukocytes are part of your body's defense system and may still be present as they finish their course of getting rid of the infection. Nitrites are a by-product of bacteria that cause the UTI. Since it is negative, likely the infection has cleared. If you develop symptoms again, see your PCP for a re-check
