Find an Allergy Testing provider in Diamond Bar, CA

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.

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.

I was very surprised with my experience here. My appointment was made very quickly. I was seen in a very short period of time. My test results came back in a very timely manner. I was able to speak with a doctor soon after and was taking care of. I was very satisfied with the experience I had here. I definitely recommend using them for any issues you have or any questions you may have.

Great discreet service, scheduled my visit and paid for for the test online not in Showed up at lab, checked in and was seen within minutes. Blood and urine were collected, test results came back quickly within 2 days because I did my test on a Friday. Quick, easy and cheap. Didn't have to wait for a visit to my PCP, and then get referral to lab.

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.

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.
