My experience this morning at the Quest Center was excellent. I was taken back on time to have my blood drawn. The phlebotomist, Angelina was very friendly, professional, and knowledgeable. The staff greeted you in the waiting room, announcing your name with, "Good morning, how are you today?"

Amanda at Quest Diagnostics on Neapolitan in Naples, Florida was excellent drawing blood and was very knowledgeable in explaining what type of tests I was getting. I would highly recommend her and what a wonderful staff.

They just opened Quest Labs in Camillus, NY. There is ONLY ONE PERSON WORKING. What kind of company has only one employee onsite? At least have TWO. It shouldn't take 2 hours to get a walk in lab done. I feel sorry for the single employee. What kind of company does this to their employees???? One person in the office doing all jobs. Will not go there again.. Will use Lab Alliance instead.

This place is a living train wreck going backwards! Having worked in healthcare for over 20 yrs., hiring clinicians and working in hospitals I can say with some confidence this is one of the worst draw sites I have ever seen, visited or worked with. My suggestion is to run. Don't walk away from this site, use anyone else but these folks are working blind. The phlebotomist I saw was WAY past her gifted prime and seemed unable to use the site software - clearly at the end of the day I was fortunate that she was unable to pull a blood sample - my lucky day!!

They fail to pass on claims to secondary providers and take payments from the credit card they have on file for you. They say they are not mandated to pass on claims to secondary providers on 3/132026 I had blood work done and payment was denied by Medicare. They billed me and never forwarded the claim to my secondary provider, BC/BS before charging my credit card.

After an appointment with my doctor, he asked me to have blood drawn. Sent me to Quest where I made appointment for after lunch since it was a non fasting blood draw. Check-in and payment went smoothly but my issue is with the phlebotomist. She stuck me then kept pulling needle almost out and gouging me. She finally just started rolling needle around in my arm until she got a vein. I am sore, bruised and have a huge knot now where she stuck me. She definitely needs to go back for more training. I have been stuck many times and this is the first time this has happened. I am a healthy man, had eaten and was very hydrated. I will not ever use this particular facility again and hope I don’t develop a blood clot from her ineptitude. The two stars I gave are for check-in and billing.

NEVER use Quest labs! They charged me instead of charging my insurance, and I won't be able to get that money back. Tried emailing, tried calling, got seriously unhelpful people. Quest labs is in network for my insurance, but guess what, if they charge the person direct, they don't have to provide the same discounts they provide my insurance, so they basically stole a serious amount of money from me, because they refuse to run my labs through my insurance like I asked them to TWICE! I will NEVER use Quest labs again, EVER! I should have done my research before I used them. Expensive lesson learned. This is the most horrible lab place ever. DO NOT USE!

Impressively bad service! I checked in as a walk in at the Poway lab and the machine informed me I could be waiting for 60-90 minutes. I was expecting a wait as I did not have an appointment, and I was fine with that. There was one lab tech working and she informed everyone she was the only one there. Another tech arrived and the first one left. I waited for a total of 1 hour 20 minutes before the second tech came out and checked in with everyone. She informed me that because I was a walk in I would not be seen right away and I could be there the whole day. It was 11:20 am and I was fasting. I let her know I had been waiting for almost an hour and a half.
She said they had an unforeseen emergency and they could not see me then. There was no apparent emergency in the time I had been waiting. This is the worst Quest office I have ever been to and I won't be going back. They need to hire more staff and be considerate of their patients. It is not a surprise that they have 2 star reviews.

Quest takes too long to report results especially results critical to Medication adjustment. 3-4 Days is unacceptable.

Over a week ago, I had a blood draw for a critically important lifechanging test. As of now, there is no sign of a result. I can't even get an ETA of when they might get around to completing the test. Inquiries are routed directly to AI Bots that have been programmed to be as unhelpful as any human could possibly be. Their website rarely loads and will often just display the message, "oops, something went wrong." Honestly, that phrase should be this company's motto. It would be difficult to find an organization that is less responsive to its customers. This is certainly not the company to entrust with your health.

Every time we get bloodwork we provide two insurance cards. We ALWAYS receive a bill for a copayment that should have been sent to the secondary insurance. When I call, I have to wait a long time before talking to someone to get it straightened out. Without fail, I then get a past due bill in the mail. I’ve called to escalate a complaint regarding the billing dept and was told I would receive a callback from a supervisor. That was three days ago. I guess no one at Quest cares. 🤦🏻♀️

Was given runaround 4 times within 10 days with wrong # of the containers for the stool samples collections. Every time I took the samples in, I was told someone made a mistake and did not give the correct # of tubes for the Samples. I had to wait for another day to collect another sample, freeze for 24 hours, make another appointment & go back, and only to be told yet again, someone did not read the prescription right and I would need another sample to bring in. They blamed me for not asking If they were giving me the right number of tubes. A Maria, with heavy Hispanic accent said: Quest does not train employees well, and I should have taken the person's name who gave me the wrong # of tubes for collection. Another excuse was that the software used by Quest would not give them the correct #s unless they printed the labels. Another was that there is no manager there to monitor everything works correctly!!
One of them even told me that it happens all the time, but not many complain because they understand mistakes can happen!!! All in all the most incompetent, time wasting, intellectually limited, untrained group of staff gathered in one place.. I have had to take 3 different days off of work to be able to collect stool samples, freeze and make another appointment and go back. Absolute nightmare.. My experience shall be shared on all my social media. Throughout the nightmare of going back and forth, there was never one time apology, and with an audacity rarely heard of, a woman by the name of Maria, at the N. Dale Mabry, Tampa, FL. location, suggested that I should go online and leave a positive and nice recommendation for them!!! I have left a message for the regional or a VP to call me back. I need a proper explanation I was subjected to.

My comment is not so much about the service at the location. I've never had reason to complain about that. My review is of the process for making an appointment. It is painful to say the least. I had to enter so much info just to see if a specific location even HAD any appointments available. There is no way to quickly check if a given location has open appointments. LabCorp is much better in this respect.

I was not able to find the location. Patients should be notified that it is in the Catholic Health Services building. There is no sign indicating Quest Diagnostics from the road. There is only a tiny sign displayed in the window. There is no one to talk to for directions or anything. The menu doesn't work with my cell phone. I had to go back home to reschedule. Your waiting room is too small and overcrowded. The keypad is confusing and difficult to use. I've fasted for nothing. I am extremely dissatisfied with your entire operation.

Very disappointed with new Quest check in process, when you can not text "I am here" anymore. This make the scheduled appointment more difficult, more time for check in. People who has a scheduled appointment has to stay in line together with people who comes as walk in for checking in and scanning documents which can make you late and cancel your previously scheduled appointment!! Very bad wrong decision!

Quest Diagnostics has no sympathy for senior citizens or cancer patients. After my pathology report came back with lung cancer, Quest ran a Solid Tumor Genomic Sequencing Test. The doctor ordered it through Quest, and I was not informed until I received a bill. The test helps determine next steps, including immunotherapy.
Insurance denied the claim because they said it was not medically necessary (even though a doctor ordered it). Insurance would have paid $842 for the claim, if it had approved it. The original bill was for $5719. After 7 1/2 hours of conversations with insurance, my doctor, and Quest, I finally contacted Quest and said I would pay the $842 that insurance wouldn't. NO, they wanted the full billing amount of $5719 paid. I think it is so sad that a cancer patient with limited funds has to pay $5719 while a multi-million dollar insurance company only has to pay $842. There is no discounted amount to be offered to me. Finally, as a side note, no one I spoke to on the 5 calls to Quest, expressed any sympathy for my cancer journey or the stress this huge bill was causing.

McCandless, Pittsburgh, PA. Mar 25, '26 Photo of resolving bruise 4 days later. Young lady was not friendly and thought I was mad at her for wanting to confirm the lab orders from 2 different doctors so that all the tests were accounted for. Everyone should do that and the lady should have welcomed the customer's oversight. She also left me with a bruise and the 'draw' was painful. The overnight results are appreciated but more training is needed for staff. She was well-groomed and her make up likely took hours, but I'd prefer better people skills.

Went to Quest Diagnostics on Aliante Pkwy, North Las Vegas, NV. My PCP sent in an order in December for a complete blood workup in March. My urologist gave me a paper order to be done in March. I made an appointment online for 12 March at 740am. I told the tech that I had the paper order and my PCP resent an order on March 2. She said she had seen both orders. She only 1 vial of blood. I questioned that, as they usually take 3. She told me she had what she needed.
When I got my test results online, they only did the PSA test from my urologist. They did NOT run any tests my PCP asked for. Is it now my job at Quest Diagnostics after they draw my blood to put on a white lab coat and follow my specimens to the lab to make sure they do the required tests? The people they hire are either illiterate, or they do NOT care about the patient, it's just a job and a paycheck. They would be as happy in a job asking if a person wants "fries with that Big Mac". To tell the truth, that is the job they would be better off doing.

A HUGE thank you to Lisa M. G. in the billing department in Norristown, PA. I had labs done on 5/21/2025 and my doctor's office coded it wrong. I called many times to Quest. They sent the form to have the corrections made to my doctor, and nothing got done. Lisa could hear the desperation in my voice to get this solved after NINE MONTHS of trying. She tried to get them on the phone on a 3-way call, but no luck. She then gave me her direct contact information so I could physically take it to my doctor's office and demand the corrections. Finally, success! It would have never been resolved without Lisa's help.

I paid the bill Quest sent me and then my insurance company also paid. I contacted Quest at least 10 times and each time was told by the agent that I was not owed a refund. I faxed Quest the EOB from my insurance company showing they paid, I provided the date and check number of the check that Quest cashed from my insurance company. Every agent I spoke with told me that was not true and I was responsible for the full amount. After several hours on hold, several complaints to the BBB, several calls to supervisors, I finally spoke with a supervisor who got me the refund (or at least he said it's in the mail). It's unfortunate that every single agent I spoke with couldn't be bothered to help.

I had an appointment this morning at 10:00 am at Quest Diagnostics on Stirling Road and Palm Ave. In Cooper City, Fl. I had a very bad experience with the tech in room #3. She asked me which arm is the best to get my vein. I replied the right one, she inserted the needled and started moving the needle to be able to get my vein. I said, "Please don't do that, you can try another vein." Unable to find a vein on my left arm, she poked me on a vein in my left hand. She was not able to draw blood. I asked her to please get someone else to get my blood. The manager came in and apologize on her behalf and was able to get my blood on my left arm. I apologize to the tech, saying that I don't mean to hurt her feelings, but I don't like to be poked several times. Her response was, "You are rude. My name is (i don't remember) Next time you come in make sure you don't come to room three." Very unprofessional behavior.

I was told by Quest in Salinas that if I wanted to wait 1-2 hours that I might be able to see someone as a walk in. He said that it was unlikely that I would be seen. I was merely dropping off a specimen. He said that they accept walk-ins beginning at 7 and I should have been there then-to which I replied that the website DOES NOT say that to which he replied, "we don't tell everyone". My thought was then how do we know that. Their.

Two visits so far. Easy Check-in (mobile or KIOSK), called in for lab work very close to scheduled appointment times. Collection was easy, fast and painless with printed prescription. Staff was very pleasant as well as professional. Needed to call and speak with Client Services regarding test results and that call went as expected. I did wait 20 min before speaking with someone. I will be going back when needed.

Very polite and great customer service. I would give a 5 but that is all the check in automated service. It prompted me to wait out in my car and get a text. I made an appointment for 7 mins ahead for 12:40 and checked in at 12:33. I was gone only 4 mins but came back in and waited 15 mins. Craig was very helpful when he came out and I asked him about it. He had already called my name. But very helpful and took me right back and very good service. Very professional.

Customer service with Quest Diagnostics at local locations is non-existent. So if you have a general question you will have to take time out of your day, drive to the lab servicing you, go inside the building, and ask the general question. Don't bother calling the national service number as the info is worthless. If customer service is this bad, I question the accuracy of the testing services. I will take my lab needs to someone else in the future.

Lab tech did a good job in withdrawing my blood work, but the lobby is extremely dirty and unwelcoming, it’s look like a prison lobby and not a clean lab. It’s super plain and smells. I’m referring to the location on 1st street in Fresno, CA. Bathrooms are dirty also. Overall, the physical location of the lab (inside) is poor in hygiene, lacks welcoming lobby, and seems cold lack of humanity. I gave it a 3 star review only because my blood tech, Cristian, was a professional and very polite and patient. He explained the work order and what he was doing each time. Otherwise, I may have given a 1 start. I didn’t take photo of lobby because it’s prohibited 🚫.

How I miss Lake Hospital and their great customer service with the lab. Now that Quest Diagnostics is doing the lab work for University Hospital I find it so frustrating. Don't even think about showing up without an appointment otherwise you'll spend hours waiting in the lab. And of course the customer service in the lab is nonexistent. And trying to get the Quest Diagnostic portal to work is like impossible.

I was at Quest Labs at 5960 Beach Blvd in Jacksonville, FL 32207. I had over 8 blood tests to be performed. There was a question about one of the tests so they had to call the ordering physician. That unfortunately took much longer than expected so I was there over an hour (I was taken to the back right away since I had a scheduled appointment). ** was VERY patient with the doctor's office lack of response and had to call several times but she never gave up. She handled the situation beautifully with professionalism and patience and never got bewildered. She even had a sense of humor about it. She was great and I hope she gets to see this post.

Do we have zero star? That's what they deserve. I have used my current insurance for more than 10 years. Each year after my annual physical lab test, they always send a bill and ask to buy up receipt. They always send my bill to the insurance I used 10 years ago! I called them a few times and they never update it. I guess it's because they ask me for a few hundreds and they only can get from my insurance for 1/10th as they asked.

My physician ordered routine blood work back in January 2025. My insurance did not pay for one of the tests and stated that I do not owe for it, either, based on Quest's agreement with the insurance. Quest continues to bill me for over $160 for this test, despite my insurance reps contacting Quest multiple times and my mailing the paperwork that Quest requested to resolve this issue 3 times. I know that they received it, as I mailed it certified and have the information when it was received by Quest. Ohio Health made the change to Quest, and it has certainly not been for the patients' benefits.
