Quest Diagnostics offers a range of lab services, including COVID-19 antibody testing by appointment, routine lab tests, and specialized pediatric services. Located inside the Sharp Rees-Stealy San Carlos Building, the main entrance is across the parking lot. The facility is well-organized, and check-in is generally easy, though some patients express a preference for human interaction over the self-check-in kiosks. The staff is noted for their professionalism and friendliness, with specific mentions of employees who provide excellent service. Patients appreciate the timely appointments, often being called right on time with minimal wait times. However, some visitors find the location difficult to navigate, leading to confusion in locating the entrance. Despite this, parking is sufficient, albeit a bit distant.
