Lab tests near me
in Ontario, CA

I was feeling faint/weak so when I walked in, the receptionist got me to an exam room immediately. The Dr. and his assistant really listened to me and preformed each test I asked for. Very thorough and great staff. I have come another time when I wasn't feeling well, and would come back again if I don't feel well.

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 would 100% recommend this company to anyone wanting to check their health status. The process was incredibly easy and done through certified labs. The results are frequently back by the next day.

I thought it was extremely easy to book a lab test appointment with Quest. Getting the test done was simple and so was the getting the results! Great job putting together something so user friendly.

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.

I tested positive for Covid on Thursday night and I made an appointment for telehealth because I didn’t want to leave my house;I was too sick.  The Dr was awesome and listened to my concerns about taking Paxflovid that has many side effects.  She recommended I purchase a pulse oximeter to check my oxygen levels which I ordered right after our call.   Costa Mesa urgent care has always given me excellent service during my various health crisis in person and now with Telehealth.  I am glad they are there when I need them

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.

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.
