Customer service is nearly non-existent. They do not answer the phone. There is no receptionist at the front desk. You sign in on a kiosk. There is no way to ask a questions prior to your visit, or verify that your labwork was received until they bring you back to a room to draw blood. So you wait for nothing. It's 2026 and clearly faxing orders doesn't work well, so it's time to use a different system of delivery. The phlebotomists are good at their job. It's the business model and technology used that I have issue with.

Takes too long to get lab results
Scheduling apt was easy and efficient, office procedure was timely, phlebotomist was friendly accurate with blood draw. Processing of labs took way to long to get results for simple routine labs. Had to cancel my MD follow-up apt due to labs not being completed in a timely manner. I made several calls requesting to be expedited, with no success. I’ll probably get labs done at lab corp in the future. It’s where my MD told me to go in the first place, but I had an account with Sonora Quest and have been getting my labs done by them for years. Time for a change, for sure!

Check before you service someone and bill them.
I did not know my doctor was not in their network. Instead of them telling me , they did the work and then billed me for seven hundred and something. They were wrong for that... If someone is not in their network and it shows up that it is not,they should let that person know that, instead of doing the service then billed them. That is money I do not have...just wrong I do not remember the exact date but it was in march or april of this year 2025

I schedule my appointment on my lunch…
I scheduled my appointment on my lunch break at the Gateway location. The room was full, everyone was running late. The room stunk. There was no staff on site to ask questions. Horrible, service. Insurance companies have to do better on contracting other companies.

I’m not quite sure what has happened to…
I’m not quite sure what has happened to this lab. I use to work with them and we use to get tests back in time. It has changed to nearly twice as long to get lab tests results. Not sure if the pathology department or in general all employee departments are understaffed. I’ll have to go to Lab Corp to see if there is a difference. Sad what has happened. They are also sending tests to California they said for testing at Quest. I feel bad for patients in arizona. Patients rely on testing results for their health and if they don’t get them in time during the period promised there are major consequences. * update on this review. I found out today the lab technician messed up my test results and or lost them from the lab, I have been waiting for double the amount of time for my results and they didn’t bother to tell me. My doctor was waiting for the same amount of time calling them to try to see what happened with my test and they didn’t even tell us. This is complete malpractice.because I can’t get treated without this test result I am heading to emergency room to get a test. Terrible awful awful awful lab. I worked with them in pathology for over 12 years and I am disgusted

Rude Receptionist and Overcharging
I went for routine physician ordered lab work on E. Brown, Mesa. I was given a form which I was told I had to sign that stated if the Vitamin D portion of the test was not covered, or if it was not covered by my insurance, I would be billed $150. I questioned this and requested my lab orders back so I could go outside and call my insurance company. I was not given the lab orders back, but went outside and called my insurance company anyway. Without the diagnostic codes, they could only give me general coverage information which was the test was not paid for if it was a screening test without medical necessity...which I believed it would be, but Sonora Quest was not going to bill that part of the test because they said the doctor did not provide a code justifying the test.
The phlebotomist was very nice to me and said when I came back in to just come back up to the counter and he'd take me right back. He had already asked someone at the counter what to do to help me, but he came back and said I had to sign the form. I told him I couldn't take the chance in paying $150 because I could not afford it.
Anyway, I came back in and stopped at the counter. "Andrea" (on-dre-uh) ignored me, never looked up at me
and eventually commanded me to take a seat. I said I had a question, she commanded me again to take a seat. I said you don't know my name. She still did not look at me, but stated "You're the only one on "Pause" on the screen. I told her she was being rude, she still did not look at me and said nothing. I sat down and a few minutes later another staff member called me up. I asked my question, which was if I could add the Vitamin D test as a self-pay patient and how much was it. I was allowed to do this, the cost was $47. By this time, Andrea had left the reception area and had not returned by the time I was finished with my blood draw.
Four concerns:
1. Trying to force me to sign the promissory note for $150 before lab work would be done. They were not even going to bill my insurance for the Vitamin D test, which meant, per my insurance customer service rep, that I could not appeal the coverage denial if they did not pay for it.
2. Trying to force me to sign a responsibility bill for a much higher price than a self-pay patient pays. $150 versus $47 self-pay.
3. Now, I am out $47 because they would not work with me in contacting my physician for clarification; would not give me my lab orders back with the diagnostic codes to give my insurance rep when I called them, or to just leave if I needed to. I believe they mishandled me, and should refund my $47.
4. I believe Andrea was the person that Timothy spoke with when I did not want to sign the promissory note, and that she made a judgement against me that was then reflected in her rude behavior toward me. Why would I sign for something when I cannot afford to pay it. I am recently retired with a limited income.
I have no complaint against the phlebotomist, Timothy, as he was doing what he was told to do.
