This is a horrible company that only takes advantage of clients and their wellbeing. First off everything is way overpriced. I can get lab tests from other companies for the same amount out of pocket that I have to pay Quest after they charge my health insurance absurd amounts. My biggest gripe is that everything is automated. I paid my overdue bill last time I was in for a lab test and they are still sending me a bill for it. Worst part is that I can’t get ahold of an actual human to dispute the charge that I already paid. The automated system doesn’t even give you that option, they just want you to pay it. It might only be $17 but I refuse to pay twice when they already overcharge. Very unethical company taking advantage of the healthcare system in place here in America.

My appointment was set ahead of time for 9:40am, but I was not seen until 11:30am... totally unacceptable!

Quest Online appointment scheduling has not been working for at least 2 days. Tried many times to make an appointment. I just have to drop off a frozen sample and honestly dont mind waiting for my now walk in appointment BUT I asked at the door when it opened could they just take the sample I'm dropping off to freeze it and the answer was sorry you have to wait your turn. The fact that there's a waiting room with no personal attention for anyone is ridiculous. Last time I'll use quest ever.

Quest lab uses a like masking tape after taking the blood sample, the big problems for senior citizens is that when taking out the tape in the house the tape take out your skin and this may be the motive that the skin gets infections beside it is very cruel from them. Masking tape is for warehouse uses.

Erika, my phlebotomist was terrific! I use the Roslyn NY location and the staff are terrific. The clientele around here tend to be really difficult, so that fact that they are so nice is amazing. Blood draws are painless. Purchasing tests online is very easy too.

Got a bill for 1500 dollars saw they billed wrong insurance. Called had them correct. Than got bill for 163.00, should have been zero. Called again after Called my insurance company found out wrong codes used and they notified Qwest. Got a name and number for Qwedt to call to fix. Qwedt said would do and put hold on bill so no more notices. Today Got bill saying pay now or late. Qwedt never called my insurance or corrected billing code. From others I know this is common with Qwedt. They make mistake say will fix and than do nothing. Company cares only about money and not service.
