There is no test drop off if the kit was finished at home. I had to wait 1 hour for labs that I wanted to drop off. It does not have an efficient prioritization system and there is no customer service representative on the phone lines for patients.

I have been using quest over a number…
I have been using quest over a number of years and I'm surprised to find out that the records they keep are very inaccurate. Their website is not user friendly. If my doctors are using quest for my blood draws on my physicals I'm going to think twice about using that doctor.

No staffing on phone
1 for mainly their corporate actions and spending 2+ hours on hold. HOWEVER my local lab tech was fantastic.

Horrible experience with Quest Diagnostics in Staten Island, New York (Clove Road Location)
I had a horrible experience with Quest Diagnostics in Staten Island, New York at their Clove Road location. First, I made an appointment on their website to have a lab test done on Staten Island at their Clove Road location. When I made the appointment, I did not realize that I needed the doctor's script in order to get the lab test done, so alerting patients that the written script is needed should be a requirement when making an appointment. The lab doctor who saw me said to come back with the written script, and that the test was available, as long as I had the written script from my doctor. I then made an appointment to see my primary doctor, which took over two months as he was busy and did not have any availability, and then received the written script from him. Then, I went back to Quest Diagnostics (same location) as told to get the lab test done, and I was told that it was not available at all.
The lab person was very rude. She kept the door open, and made a very rude comment to me because I pointed to my birthdate when asked, as I did not want all of my health information being shared with others, as she kept the door wide open, which is actually a HIPAA violation of my personal health information, and she had the gaul and the nerve to say that I did not know certain information because I kept on pointing to it on my ID card, when in fact I was trying to be discreet and not have everyone know my personal information, as the door was wide open. Then, after informing me that the test the doctor ordered was not available, I said why was I told that it would be available, and to come back once I had the script? She said well maybe if you had the script with the test on it, which I did not initially have, then I could tell you if we have it or not. I said I did not have the script with me the fist time, but I did in fact say "this is the test that I want, is it available?" and I was told yes, it was available, but to come back with the written script for it, and they would do it. I experienced anguish, and the people were rude.
Do not every go to Quest for any lab work or services!!
On a much better note, I experienced a world of difference with Northwell Health Labs! I would strongly recommend going to Northwell Health for any of your lab work or tests, they made a world of difference, and even knew the bad reputation that Quest now has. When I went to Northwell Health, they had a sign up of all of the information that they need, including the doctor's script, and your ID card and insurance cards. And, all of the health insurance plans that they accept, including mine, were clearly listed at the front desk reception area. They were kind, courteous, knowledgeable, and professional, and asked how I was doing. I would definitely recommend them for any lab work or service.

If I can give the web site zero I…
If I can give the web site zero I would, with all the money they made how come they use a web site made by the son of an executive of quest. I spent hours not only trying to make appointments but it takes days till you access your test results. It's the most frustrating website you can imagine

Reckless quest driver
This company hires whoever. Today I was driving and one of their drivers tried to cut me off. When I was doing the speed limit he was practically on my bumper then he went around me driving on the other side to pass me then he kept stopping short so I would hit him from behind. Being that they hired a driver like that I will not go to that lab ever again. Car # 82768

Results take forever
In and out very quickly, lab tech was very good but the wait time for results is terrible. Went in a 7 am on Thursday, now it’s late afternoon on Friday and I’m still waiting for my results. Trying to speak with someone at the corporate level regarding billing is a nightmare. Impossible to speak with a real person, I will do my best not to use Quest in the future.

Intentionally overbills, Makes you go around for correction
Intentionally overbills. Doesn't correct billing till you follow up. No email address to send document except very suspecious one they tell on phone. No response when you send document whether it is ok or not and again you have to follow on phone. Waiting times for 30-60 minutes every time. Phone department doesn't talk to email departmet who doesn't talk to claims department so you just go round and round. Not recommended.
