Sharp Laboratory Services Chula Vista on Fourth Avenue in Chula Vista's downtown corridor offers walk-in and scheduled blood draws, urinalysis, and diagnostic specimen collection at Suite 7. The draw station feeds results directly into Sharp's electronic health record, giving ordering physicians at Sharp Rees-Stealy Chula Vista on H Street same-day access to chemistry panels and CBC differentials. Located one block from Third Avenue Village — Chula Vista's walkable downtown dining and retail district — the Fourth Avenue lab provides a convenient draw site for patients who work or live in the western commercial zone near Broadway. Specimen volume from this location supplements the testing capacity of the larger hospital-based laboratory at Scripps Mercy Hospital Chula Vista, giving South Bay patients two distinct outpatient collection options along the H Street medical corridor. The facility processes phlebotomy orders for prothrombin time, hemoglobin A1c, lipid panels, and thyroid-stimulating hormone assays using vacuum-sealed Vacutainer systems routed to Sharp's regional reference lab for automated analysis.
