Quest Diagnostics

Medical Labs
Hours: Quest Diagnostics is located in Diablo Plaza next to Regal Crow Canyon Cinemas, with an entrance by the McDonald's restaurant. It offers routine lab tests, pediatric specialty services, glucose tolerance tests, and Blueprint for Wellness biometrics, along with standard blood and urine testing. COVID-19 antibody testing is available by appointment, with specific requirements. The clinic is noted for being extremely clean, sanitized, and less crowded, with ample parking. The phlebotomists are consistently described as friendly, polite, kind, professional, efficient, skilled, and highly qualified. They provide excellent customer service, are fast and accurate during procedures, and are adept at drawing blood from difficult patients. Making an appointment online is emphasized as a must, as it makes the process easier and faster, leading to very short wait times and a smooth experience. Patients report being in and out quickly, often in about ten minutes. Results are received quickly, especially when using the Quest app. However, the check-in process receives criticism. It requires filling out information and scanning identification and insurance cards at a self-service kiosk every visit, even after pre-registering online, which some find annoying. Overall, despite some procedural frustrations and mixed online ratings, the location is highly recommended for its professional staff, clean facility, efficiency, and skilled service.
