Lab tests near me
in Diamond Bar, CA

Thank you to the Ma , front desk and the NP for treating me today. Thank you for everything you do and for having empathy.

I came in at 5pm off the streets in severe pain and Dr. RITTER gave me excellent care and more knowledge in one session than my current Doctor did in 4 months! Think he's great and would recommend all clients in pain to see him. Thanks D.G.

After receiving my results, I called Quest Lab Testing and discussed the results with a consultation. This consultation filled in my knowledge gaps and made me more aware of my particular situation.

I was able to choose a Quest lab location and schedule an appointment. Check in was easy, and I only needed to provide my name and DOB. They were able to locate my order in their system. They were already aware that my labs were paid for prior to the appointment. I had my labs done on a Wednesday, and I received my results by Saturday. Great experience.

Excellent customer service. Knowledgeably answered all questions. Appointment and billing were fast. Testing next day was on time and professional. Results available within 24 hours. Highly recommend.

I came in one day without an appoint and waited two hours as a walk-in before I had to leave without being tested. I made an appointment through Quest Lab Testing for the next day, showed up on time, got tested easily and was on my way in 15-20 minutes. Staff is friendly and helpful.

A great experience for something I had a lot of anxiety about. Had no wait time or issues at the testing center/lab. Had blood drawn at 3pm and had results by email at 9am the next morning.
