Sharp Rees-Stealy Chula Vista Laboratory on H Street processes outpatient specimens from the first floor of the 480 H Street medical building, serving as a core draw station for San Diego's oldest multispecialty medical group, founded in 1923. The lab supports same-day specimen processing for patients seen at the co-located urgent care clinic — Sharp Rees-Stealy Chula Vista Urgent Care — where acute illness and injury workups frequently require stat CBC, metabolic panels, and rapid strep or influenza testing. Sharp Rees-Stealy Medical Group now employs over 700 physicians and advanced practice providers across 19 San Diego County locations, with the H Street campus serving as a primary care hub for western Chula Vista. The lab's integration with the broader Sharp electronic health record allows results to flow to referring providers across the H Street medical corridor, including optometrists at H Street Optometry who order diabetic retinopathy screening bloodwork. Automated analyzers at this station process glucose tolerance tests, iron studies, and comprehensive metabolic panels using centrifuged serum samples prepared on-site before transfer to Sharp's regional reference laboratory.
