    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.

    My appointment was very expedient with Ambrosia, a very competent tech. She deserves kudos.

      I changed from LabCorp to Quest and this is the best decision I have ever made. The staff are friendly and have more patience. Shout out to Moriel from Las Vegas, St Rose facility, I am a hard stick and she got my vein for the first time. Highly recommended.

      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.

      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.

      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.
