So I have an appointment and it says that you can use your phone to help with the check in progress. I opened the door and immediately get yelled at to wait outside. Poor customer service!

This is the absolute worst place in the world to go.. 2627 Hylan Blvd - DIANA has the empathy of a bullfrog!! My husband waited for 2 1/2 hours - nothing.. No one was there - online said 3-minute walk-in wait time.. Nice.. It costs nothing to be empathetic & kind... We will never use Quest again... Never..

My rheumatoid arthritis doctor had me go to quest diagnostic for a blood test to change my medication. The results came out that I had hepatitis A and hepatitis B infections. I had a second and third blood test the next two months to see if it changed. It did not. It showed I still had both infections. I was then sent to a specialist at the University of Chicago who ran those blood tests and many more to analyze having hepatitis A and hepatitis B. All of the blood test turned out negative, showing I had never had hepatitis a or hepatitis B. I would not recommend this lab due to all of the false positives. I have contacted quest diagnostic to see why this may have been. They have not reached out to me.

I got some blood work done at my doctor's office & for some reason they use this company for the tests. I got several bills through the mail saying that I owe Quest Diagnostics money for my tests. I went on their website & set up an account, put in all my insurance information & got an auto email back saying "It may take up to 5 business days for your insurance request to be processed." So I think everything is all good & they will take care of it. A few months later, I get more bills in the mail saying it's very overdue?? This company never even contacted my insurance & I had to pay it before they went after my credit score. They have no phone number to call & no one ever contacted me saying I had to contact my insurance. Their website is misleading saying they will contact them for me. Very frustrating & I had to pay almost $1000 that they then had to refund me because my insurance covered it. Huge waste of time. Avoid Quest Diagnostics if you can!

Horrible service, scheduled an appointment today for 2:00 P.M. Arrived at 1:45. 45 minutes later and just saw one person come out. People are still sitting around that had appointments for 1:30. Totally ridiculous. Never again. Whoever does the scheduling should be fired.

Had absolutely no problem at this location. Scheduled an appointment online for 11:45 on their site. Was able to enter my Insurance information as well to save time. Received a confirmation #, an email with the confirmation as well as a barcode to present at Quest for them to scan. Arrived at 11:30. Waited outside entrance (with three others) for about 5 minutes when an employee came out to verify our names & times. After that we entered the waiting area where we were temperature checked & given hand sanitizer. I was then sent to a cubicle and the technician verified who I was. Presented ID, Insurance Card & Confirmation Barcode. Blood taken. DONE. Not even 15 minutes from start to finish. If you arrive on time & have all your information ready this location is no problem at all. The waiting room had four people inside who were waiting because they were either late (one guy over a half an hour) or didn't have proof of insurance or proper ID with them, one person waiting for a fax from their doctor's office. I could tell that the staff was relieved & surprised that I gave them no problems. I can only imagine the nonsense they have to deal with from the small sampling I saw while there. Come prepared & on time

Wish I could rate a 0 star. I got a covid test done at an urgent care facility and they said that I would be able to view my results the fastest way through quest diagnostics. I made an account and an error message kept popping up saying I needed to verify my SSN. Every time I entered it, it said it was not correct. I tried to send a complaint to customer service and it wouldn’t even let me send that. I tried to use to call quest, use their live customer service chat, I got through to nothing but a computer on both. It is IMPOSSIBLE to get your covid results on this website. Absolutely ridiculous. I consider myself to be a very tech savvy person so I cannot imagine how hard this would be for someone who is not.

It is impossible to get someone on the phone! And when I finally did (probably one hour later with no option of a call back), the lady was rude!! I hope that your physician's office is not working with Quest, so you don't have to experience their customer service.
