Labcorp operates a Patient Service Center at 5555 Reservoir Drive, Suite 101, in San Diego's Allied Gardens, processing routine blood draws, pediatric specimen collection, H. pylori breath tests, glucose tolerance tests, lactose tolerance tests, and paternity testing. The center accepts walk-ins alongside scheduled appointments, and physicians across the 92120 ZIP order lab work through Labcorp's portal for panels ranging from basic metabolic profiles and lipid screens to thyroid function and hemoglobin A1C. The Reservoir Drive medical office building also houses Spectrum Eye Clinic + MedSpa upstairs in Suite 201, creating a multi-specialty cluster where patients can complete lab draws and ophthalmology appointments in the same visit. Labcorp (NYSE: LH), headquartered in Burlington, North Carolina, employs approximately 61,000 people globally and processes tests on more than 2.5 million patient specimens per week across its clinical laboratory network. Results post to the Labcorp Patient Portal, giving patients and ordering physicians access to finalized reports within the same electronic system. Urgent care providers ordering stat bloodwork for acute presentations also use this draw station, and Perlman Clinic Mission Gorge in Grantville routes lab orders through Labcorp for patients who need same-day metabolic panels or complete blood counts. The center occupies a ground-floor suite with wheelchair-accessible parking in the Reservoir Drive lot, positioned near the Alvarado Hospital corridor that connects Allied Gardens to Grantville along the Interstate 8 frontage.
