Walk-in express care for patients ages six months and older operates in downtown San Diego at UC San Diego Health – Downtown, serving the 203 F Street corridor. The clinic delivers same-day treatment for minor acute conditions—including respiratory infections, sprains, lacerations, and UTIs—with point-of-care testing that returns results before discharge, a community-health model paralleled by FamilyHealth at City College in the East Village. UC San Diego Health established its clinical network in 1966 as the region's only academic medical system, now offering video-visit express care options alongside in-person walk-in service at this downtown location. On-site diagnostic capabilities cover rapid strep, influenza, COVID-19, and urinalysis panels, plus pregnancy testing, gynecological screenings, and seasonal vaccination administration. Cases exceeding express-care scope—including fractures requiring radiographs, chest pain evaluation, or high-acuity trauma—route to the full urgent-care department at Sharp Rees-Stealy Downtown Urgent Care on Fir Street for advanced triage capabilities. The facility administers CLIA-waived rapid diagnostic assays—including antigen-based influenza A/B, Group A Streptococcus, and SARS-CoV-2 panels—delivering actionable lab results at the point of care before patient discharge.
