Potentially eligible participants will be scheduled for an eligibility screening session, followed by an extensive baseline phenotyping session, which together are expected to take approximately 2.5 hours to complete. Participants will be provided with breaks as needed during the clinic visit. The eligibility screening session is intended to collect the minimally sufficient data to confirm eligibility, so that the extensive baseline phenotyping session is initiated only for participants highly likely to be confirmed after the 48 hour urine culture results are known.
