After the first visit (Day 0 after signing consent) blood and urine will be collected, subjects will be put into either ASB Positive or ASB Negative groups based upon the results of their urine culture. From that point, those who test into the ASB Negative group will have an additional urine culture, either by returning to the clinic or by sending a urine culture mailer kit, and if cultures remain negative, they will be discharged from the study after reviewing medications, adverse events and completing a urinary tract infection risk questionnaire.
