I have tried multiple times to submit my insurance info. by completing the insurance side of a bill and mailing it to you. I keep getting the same bills with indication that you do not have enough insurance information to file with Medicare and my secondary insurance. Today, I called the TBR billing dept. and was told that, “the reality is that if you don’t submit a check with the bill, the insurance side will not be read and the bill will be shredded.” Are you kidding???? This is totally unacceptable and I will NOT send a check until you file with Medicare and my secondary insurance.

It amazes me that you have a file on me that your rep referenced, but will not store my insurance information in that file for future use. I was told that I will have to submit the insurance EACH TIME I have lab work done. The solution to that is to not use Quest for lab work.

I was also told to “speak sternly” with Dr.Stewart, as they should have submitted the insurance information. I called their office and was given another runaround. IF you want payment, you need to keep my insurance on file and submit my bills to Medicare and my secondary insurance.

Beyond being aggravated, this isn’t even cost efficient for you! Toni Gazzaniga

I had an appt today at 9:45am made through your toll free number which didn’t record it. The black employees at St. Johns Ave., Jacksonville, Fl are very rude. It took over an hour to complete the appt. Your services suck!!!

I been working with Quest for the past 3 years and I have read their Mission statement over and over and I have yet to so what this company stands for. I have experienced very unprofessional supervisors who treat their employees like they are nothing. I have experienced hate and personal issues toward employees including my self. I have filed numerous of complaints on the supervisor but instead I was wrote up on issues that didn’t make since to me. I have took every channels I could to get matters resolved but no help, I now had to take legal actions due to medical issues and compensation that was not rendered to me.I love patient care I have been in this field over 20+ years and never had write up or any major issues. I just need to know who else I can turn to or if you can search out the area Managers and Supervisors on your own to see what is really taking Place. Please point me in the right direction so things can get better and things can stand for what Quest Mission stands for.
Thank You

Your company just plain sucks. Walk in to find some crap computer that I have to use to check in and then get some rude crapa** XXXXXX when I don’t want to use it. Take your foreigners that work for you and shove it. Will be using someone else from now on!!!!

BILLING ISSUE-I will be calling the corporate office to try to resolve an issue that has been going on for five months. The lower level customer service is very unprofessional, and I can’t believe some of those employees are employed….sad a company the size of Quest can’t do better. Looking forward to speaking with a professional to resolve a billing issue that is between the doctor’s office and Quest. Surprised to see Quest won’t work with an office the size of my doctor’s office on their mistake, but instead sends me a bill and never calls back to resolve the issue.

Please have you employees trained to treat people with respect. & for God’s sake, have your policy on a banner in your office or your site. If walk-ins are welcome for real, at least take them in orderf of arrival & sign-in. They leave me waiting and didn’t even tell me that they will take appointments 1st regardless of arrival times. It is an oxymoron to have a sheet where you have to sign in, with arrival time if they don’t take you in order. It is Ok to take appointment when they arrive on time but tell the people who came first.


Mrs.khader October 11, 2017 at 2:12 pm

The absolute worst customer service on the planet!


Alma Preston October 17, 2017 at 7:54 am

You are right. They advertise “walk-ins welcome” but after you wait for service for over an hour, they tell you they take appointments first. They are rude to Hispanics too. They should advise people of their policies. Some people go over there and they are not in the best of their health, to have their blood withdrawn & their employees are impolite. The office I went is located in Warren, MI.

I had taken (TODAY – Sept 19) my 4 year old to withdraw blood at the Middle Village Queens location. As normally children are afraid, she did not want to cooperate to show her arm. I tried holding her arm but she continued crying.

The technician seem frustrated and forcibly pulled, grab and twisted her arm. I was furious and yelled at the technician. She seem to be having a bad day but this is ABSOLUTELY no reason to treat a child like this.

I had complained to her co-worker but she did not to comment and agreed to do it herself. She was doing the billing and reception. This technician was gentle and my daughter was still crying but allowed her to finish.

I am extremely disappointed at this technician. She didn’t even apologize or felt sorry for the child. Please DO NOT ALLOW this technician to handle Pediatric Blood Draw. I will file a complaint against this technician, she should be fired or suspended.

I DO NOT want any child to go through what my daughter experienced.

On August 29, 2017 I had blood drawn at your Fuquay Varina, NC location for Keppra level in preparation for a Neurologist appointment ion September 14. Two days prior I was advised that the results had not arrived. I went the the Quest office and was told that it had been faxed, and the tech had a copy as proof, but she was prevented by policy from letting me see the fax. I asked that it be re-sent. The Neurologist reported receiving the re-fax, but said that the message was that the test had not been completed. I returned to Quest with another order and had blood drawn again. The tech made me wait 1/2 hour while she tried to prove that it was not her fault, but the lab’s. At that point, she was the only one who cared about assigning blame. I asked that a rush be placed on it since my appointment was the following day. The increasingly rude tech said that she needed an order from the doctor to rush the test. I had the Neurologist send that order. Results have not been received as of 9/15. The tech was rude on each of my 3 visits. The fact that the first test was botched should have automatically qualified for STAT treatment on the second out of good customer service. The tech raised her voice to me several times, and used filthy language that offended and angered me.

For THREE days I have been trying to clarify a charge for almost $1000. Today I was on the phone for almost 4 hrs, being put on hold, listening to same recordings (I know them by heart) being turfed to other representatives who just give me another number to call & repeat the same mess all over again. What is with his company that USED to be efficient?


Cindy Walsh July 21, 2017 at 11:18 pm

For several months I have been trying to get this bill that Quest was sending. I called and told whomever answered the phone that the insurance I hàve is refusing to correct a coding error. I am disabled, I have Humana
I only go to Sutter Gould Medical Center. They have their own Lab. Instead, a bill that doesn’t belong to me, was sent to Collections. Both Medicare and my supplemental insurance Humama both say I owe nothing. Please remove this from my credit report and a cc’d to me via email. Cindy Walsh

I have been going to Peace health Labs for 8 years . Lab work was requested by my Oncologist every month and at times several times a month. Each visit was quick,efficiant and left there feeling well taken care of. Now with Quest Diagnostics, there seems to be endless problems with my information in the computers, the doctors ‘standing orders” don’t exsist. Lab results are not prompt as they were with peace health. Now I wait days for my results ,where it was hours with peace health. i am so disappointed with this new company!
