Do yourself and your blood pressure a favor, stay far away from this company. Second time I made an appointment and second time I have been screwed. There’s a reason why they have so many one star ratings. At this point, I will change doctors if I have to go back to them again.

They have a portal/database that's likely run solely on A.I. it's awful. Never can it update my address & as a result I can't get my test results. This has been an issue for over 6 years. So now I'll NEVER be using Quest again. Yet the physician ordered the bloodwork via their website & I got the bloodwork done 3 months ago. They're chat agents are a joke and no one ever answers the 800 number. Nevermind that the bloodwork tech's they hire are usually not able to speak coherent english & can't ever find me in the database b/c they can't even spell my name. I informed the tech that LE BLANC has a space between LE and BLANC but she can't understand english. She called her supervisor over & at this point I was very frustrated as they spk to each other about me in spanish & then when i explained my frustration to supervisor, she called the police and said they won't be servicing me. I had to go to a different Quest location to get these tests done. AWFUL,. STAY AWAY.!!

The guy that drew my blood billed an insurance from 20 years ago instead of billing the insurance I gave him. Now I’m going through hell to get it corrected.

This is the worst company I’ve ever had to come across. DO NOT USE.

The Billing practice at Quest is board line criminal. Never pay the first request I'm sure it's a scam triple check you insurance and coding. They try hardest to ignore resubmitted billing while testing your patience. Happened 3 times in 10 years of simple annual blood work.

Impossible to contact a real person for any reason whatsoever. Website contact & service 'options' are a loop that goes nowhere. AI is ridiculous. AI is useless. There is a telephone number deeply buried, but it is 'not in service at this time.' DYI website booking is tedious - ridiculous. Imposdible to get help. HIRE A PERSON. Furthermore, they REQUIRE personal information they do not need - a hacker's opportunity. And you cannot change the information BECAUSE YOU CANNOT CONTACT ANYONE. Once you have an appointment, the staff (evidently a staff of one) refuses to change/update information (such as email address) and lies about being able to contact via telephone. Attitudes get nasty quickly - they likely hear a lot of complaints...

My test results were compromised because blood was left too long before centrifugation. I called customer service for a replacement test. After more than 30 minute wait time, a rep said a link for a free replacement test would be emailed to me. I never received it. I'm now 10 minutes into a 40 minute wait. The menu to get to a rep is the usual AI forced choice nightmare without a clear choice to talk to a rep. If I had an easy question, I wouldn't be asking for a rep. Do better.

my date of service 7/28/2026 , two weeks still have not received 3 lab values. 2 of those are basic zinc, and copper should never take two weeks. I paid $1200.00 direct on my consumer portal for many tests, which have returned. For days, I've emailed, tried chatting with a dumb bot, with prepopluated questions that don't fit not having received tests, two weeks there is a serious problem... No human person, or even a chat agent, thats a person can be reached. the phone numbers don't seem to work... I'm very angry having my PAID test not have been performed or lost specimen... The stupid bots, continue to email when I send a report about not receiving completed lab order its 2 weeks. the repeated useless emails continue to state my labs are now ready. The 3 missing (pending) values still show as PENDING, FOR TWO WEEKS!!!! Quest Diagnostics get a F- for failure to return a routine lab now over two weeks
