About Quest Diagnostics

Quest Diagnostics Walnut Creek La Cas Via offers a range of medical services, including COVID-19 antibody testing, routine lab tests, pediatric specialty, glucose tolerance test, and Blueprint for Wellness. The location is across from John Muir Hospital Shell Ridge Plaza and is open Monday to Friday from 7:30 am to 4:30 pm. Customers have reported positive experiences, with the staff described as attentive, caring, knowledgeable, kind, professional, competent, and responsible. The check-in process is digital, and the phlebotomists are skilled, making the experience painless and professional. Customers are advised to bring their QR code, ID, and insurance card, and for Stanford-ordered tests, to bring paper copies as the two systems don't always communicate.

    Great place to get labs done Just make sure you schedule your appointment and show up a bit early.
  • July 2026
    You won't get in without an appointment. If you do have an appointment youll be lucky to be seen within an hour. Place is clean and attendants are courteous, they just need more staff.
  • June 2026
    They run right on time for scheduled appointments. It's easy to get an appointment on one or two days notice.
