I have had blood work drawn many many times. I have had to use quest on occasion due to provider preference. Any time I have gone there there was always a problem. The first time I was turned away for being a walk-in, the second time I could not get blood drawn because Cortisol levels must be drawn very early in the morning per the lab and the computer won't let them be drawn past that time even though no appointments were available anywhere that early. I went to another lab that same day and had no problem. Third time I tried checking in on my phone and received a message that I was more than 1 minute late and needed to reschedule my appointment. There was absolutely no one waiting for blood work in the lobby, but I was turned away by the lab tech. I then went 3 doors down and walked into another lab draw facility with no problem. I have never had any of these problems at any other lab draw facility and would never recommend this place to anyone.

Worst lab ever…
I had an appointment at quest but the facility was closed due to an hvac issue. So I drove to another one 11 minutes away and got there a few minutes before it closed and was told it was closed. Now I'm at a 3rd facility. I've been waiting half an hour. There are 3 other people here. Noone has come or gone since I arrived and there are no staff members anywhere. I do hear laughing behind the window so someone must be here. I'm assuming when they close in 3 minutes I will once again be turned away. Never again will I use quest!!

The system of being able to talk to a person is nonexistent! To do anything with them you must have an appointment! Walk in for anything you don't get serviced. Just beware!

Blood test done incorrectly on my 8 week old infant.
Took my 8 week old infant for blood test at quest. Tech stuck both heels to collect lab in 2 tubes. First stick in heel was not done well well enough. Tech then stuck her other heel. When going to doctor no lab results known. Pediatric office did not have the results because Quest never performed the lab w/ my grandchild’s specimen. Reason is blood was put in wrong tube. Quest never called me to make me aware. It’s been 4 days now. I was made aware by pediatric office who researched to locate result & no test results known by Quest. Quest told them they will call me. Terrible, incompetent to not know protocol to follow for blood test on infant. Quest has not called me, been 4 days since test incorrectly performed. This is wrong.

My appointment was on 2/22/24 at 8:40…
My appointment was on 2/22/24 at 8:40 a.m. at the Newport Beach location. I was taken back behind a locked door at 9:00 a.m. There were no personnel at the front desk to speak to for any questions I had while waiting. I was concerned that my name was first on a board, and then taken off the board. I thought perhaps my name was skipped over my mistake. There was another woman in the waiting room who also thought they passed over her name as well. When my name was called at 9:00 a.m. I told the lady drawing my blood that I suffered anxiety and that I was nervous in general about waiting the extra time and having my blood drawn. She seemed completely indifferent to what I was saying; I needed to lay down. She told me that they didn't have enough people working there, and also told me that they had a problem with a test with another patient. I did not understand how that would affect my appointment time. She seemed annoyed that I was not happy, even though I was very calm when explaining how I felt. She was very rough with me to say the least, and used unnecessary force jabbing the needle into my vein. I have NEVER in my life experienced this treatment at any other lab, and it hurt to the point where I yelled out loud that I was hurt. I know others heard me. I was close to tears waiting for my horrible experience to be over. She never asked how I felt, how my arm felt, or if I was OK to stand after laying down because I can get lightheaded. She walked away and told me to leave when I wanted to. I'm 70 years old, in excellent health, and have never felt the need in the past to write about how miserable my blood draw was. I have taken a picture of my arm, as evidence, which is quite bruised as a direct result of her roughness, and my entire arm is still hurting hours later. I will let corporate know what happened to me hopefully to prevent others from being hurt. I cannot help but think her treatment of me was intentional because maybe she didn't like me or my comments. A better explanation, I hope, is that she is extremely unqualified at her job and should not be anywhere near a blood lab touching humans. Having zero compassion for a patient should be reason enough for this person to be fired let along everything else that was done to me.

Awful
Awful. Cannot talk to a human. Automated appoint schedule as flawed at best. On my 5th attempt for a simple blood draw -stuck as a stand by because system does not recognize appt scheduled by phone. Employee walked out and rudely wished me luck getting in. Horrible
