RE: Invoice # 189100619

Dear Sir or Madam:

I recently received a bill with charges for my blood test.
I used this laboratory before for many years, so I came to your company to get tested again.

As I understand it, Quest Diagnostics no longer accepts Horizon Blue Cross insurance, in which I am currently registered.

When I came to one of Quest labs located in Manalapan, New Jersey, I was asked to show my health insurance card, which even been scanned by one of your employees. I believe that I should be notified immediately that Quest does not participate in my insurance, and I will be responsible for paying for your services, like all medical institutions are doing.

During my registration, Quest employees accepted my card, made a copy of it, and entered my information into the system. None of them told me that this institution does not participate in my insurance.

I am certain that one of the reasons to check patient’s insurance information in order to be able to check whether this institution accepts it, and notify patients of the result of the verification.

I can assure you that no one even mentioned me that my insurance will not work. Otherwise, I would defiantly just go out and find another laboratory for blood testing.

I am sure that I am not responsible for the lack of professionalism of your employees; therefore, I am not obligated to pay this bill.

I respectfully request your office to look into this matter, and assist me in resolving it.
If you have any questions or concerns, please contact me at the phone numbers listed above.

On 3-9-19, I took a routine blood test at the West Boynton Beach, FL. location. The person who took my blood had to take from both arms to get enough blood. The next day I saw I had a large area of yellow around the sites. My test came back that I had high potassium, at 5.5. I too pictures of my arms, and showed them to my doctor. He said an improper blood draw can cause a high potassium level. He ordered another test. I took that one on 4-17-19, and showed the person at the desk the photos of my arms from 3-9-19. Then I showed her documentation from a website that told of the reasons for high potassium, one of which is an improper blood draw. She made sure I didn’t get the same person. The new test showed normal potassium. I should not have to pay for this 2nd test. My invoice number is 679715XXXX, Lab code MIA.

Dear Sir or Madam:
I received a statement indicating Medicare denied payment of a PSA test performed on 12/13/18. I have also received a denial from Medicare. Medicare states my doctor did not provide a code indicating it was a medical necessity. My doctor told me they have contacted Quest and provided the proper code but upon calling your toll free number on April 16, 2019 and again on May 9, 2018, I was told you have not received the new information. I asked Kristen what was the Medicare allowance for a PSA for a person with regular Medicare. She either did not know or would not tell me. She did tell me Quest demands full payment. I am asking what amount does Medicare pay for a PSA test. If it is substantially less than $148.48 why are you demanded this amount when Medicare only paid Quests $56.91 on the other charges totaling $383.55. I know my secondary carrier paid a small amount that was my share after Medicare paid. My account number is 6555816800. I am prepared to pay a fair amount if my doctor has not provided the proper code. By the same token I expect Quest to check with the local lab in McKinney Texas that performed the tests to determine if they are sitting on this information. I await your reply. Thank you. Richard S. Hill 817-773-XXXX.

I went to Quest on Cooper Rd. in Voorhees NJ ON 4/10/19 @ 10:15AM. The girl who drew my blood, Brandis was nice but she does not know what she’s doing. Once again, I got blood work from them & she did not take all of the tests outlined on the order form from my doctor (Judy Lightfoot-Rowan University Medicine) so when I went to see my dr. today I had to re-do 1/2 of the blood work again because Brandis fowled up. This is not acceptable. This is not 1st time error was made by them at that location. I no longer will be going to that office or using Quest as my insurance now allows me to use LabCorp. You need to hire & train qualified people to draw blood, understand codes & follow instructions on order form so I do not have to get blood drawn needlessly a 2nd time for same tests. I would appreciate a reply as to the corrective action you will be taking to avoid such travesties in the future. Thank you.

I went to the local Quest in Lombard, IL. I was treated rudely by racist employees as soon as I arrived! I dont know these people, so there is really no reason to treat me so respectfully .

I checked in and was kept waiting almost an hour, there was only one customer in the place! I was asked to check in in a realy sh**ty tone of voice, even though I already HAD! I expressed no disresepct!

Every word that come out of the mouth of the employee was in the sh**tiest tone of voice I have ever heard. Anyways I finally got the chance to do the urine test, and sadly the employee claimed it was out of temprature range, and we discussed it, and she noted it was 98, and I saw this, and it was in range, range on form is 90-100. The employees said she was marking my test as a refusal and committed fraud when she check the box stating that the sample was out of range, it wasnt! 98 is in range, however the employees took my phone and locked it up so I was unable to take a picture.

I was asked to stay another 3 hours and retest, this was on a friday at 2pm, this was done on my own time I wasnt getting paid for this. I declined, and the employee filed a false report and sent it on.

avoid at all costs! and if you go here, Please bring 2 or 3 witnesses as this place has rude disrepectful liars working there. Or I suggest a body cam, or some other hidden camera (without audio). piss poor pathetic people working here! not sure how a palce can run with very rude liars running it.

I also tried to call the corporate offices, after several calls they did answer, but quickly hung up on me. I called back several times no answer. poor service all around.

I have filed a complaint with consumer affairs, and will follow up with a BBB report, and I am going to be filing an affadavit as a matter of record as to what fraud occured here, and then comes the court complaints….these liars can tell their story to the judge!


Carol McCarl March 7, 2019 at 3:24 pm

I have been trying for over a year to receive a four hundred dollar refund because I was sent numerous bills insisting I owed them this money. After doing extensive research, I learned that medicare had covered all lab costs.
Now they claim I have been sent a check on two separate occasions, but I did not receive either. The person I have been working with whose name is Roger has now promised he will send it to me registered mail, but I have yet to receive it and he won’t return my calls.
Roger is a supervisor in the Tampa office.
Please help me.


Robert Swenson February 14, 2019 at 12:51 pm

I am a contractor on assignment for the American Dream project in Rutherford. Contract ends this June. I heard that your company acquired Hoffman LaRoche on Rt. 3 in NJ and would like to pursue construction project management / facilities positions that my be available. Please contact me to further discuss. My cell is 973-349-XXXX. I could onboard earlier if required.


RMichael Williams MD PhD February 12, 2019 at 6:34 pm

I am a Quest customer, a pretty good one.

On multiple occasions I have tried to call the above mentioned corporate phone number. It has never been answered, at least when I call.

If customer service has any meaning to whomever actually reads this, then I would expect to get a call from the CEO, CFO, or CMO


Tammy Robinson February 13, 2019 at 12:27 pm

We just called and the number is fine. Are you putting a “1” before the other numbers?


E March 21, 2019 at 6:53 pm

yeah the *number* is fine, just it is answered in a highly irregular way for a place that is supposed to be running a multimillion dollar bizness.


Louis Ewiing January 29, 2019 at 8:31 pm

On Jan 21, 2019 my employer Fedex had me submit a urine specimen for drug testing. To date no results have been submitted to employer nor have I been contacted by any Quest rep. This process has covered 8days causing me not to start working. Fedex test coordinator was told my specimen is in testing multiple times. When I call Quest they can’t give me any information or assistance. Today Jan 29, 2019 @approx 7:14 pm I spoke with Ron(refused to give last name) in the gerneral client services dept. He was rude and not at all helpful . His focus was on not sharing information rather than help resolve this issue. He stated I couldn’t speak to his supervisor nor file a complaint. He said if I had issue with this delay or him I needed to contact my employer and complain about your employee. My intent in contacting Quest is for someone to care enough to look into this matter and help move it forward so I can start my job.


Robert Cooms December 11, 2018 at 10:25 am

Quest keeps demanding payment from me. Says that Medicare (as secondary insurer) denied payment. Medicare has no record of any receipt of claim from Quest. Quest says it won’t provide any additional services without payment. Very unhappy with Quest Diagnostics.


Deanna Dunlap December 4, 2018 at 6:30 pm

I will send a certified letter to your President and Vice President, as well. I went in to drop off a urine specimen at Quest Diagnostics in Port Arthur, Texas and the 2 ‘ladies’ there told me of their ‘love’ for Obama and what I was, being white, and a ‘Trump’ lover. They said they hated the President and that Obama never went against the constitution (I don’t think they know what the Constitution is) and didn’t know Obama majored in Constitutional Law. They were clearly liberals and ‘both’ of them proceeded to get in “my face”. Who am I, who was I, who is my husband, who was he???? Perhaps Quest didn’t get a tax break passed by President Trump. Perhaps Quest doesn’t value the old saying: ‘the customer is always right’ and that ’employees don’t argue with customers” especially about politics. And, they sure don’t say “we hope there is a civil war and Trump will have started it”……I have people to contact. A customer should ‘never confront’ such and certainly not have 2 employees of a company against a customer, regarding liberal politics and their ‘love’ for Obama, which was said, over & over as if I was dead! This is my first time to be confronted by liberals. Its true, they don’t have open minds, they do “hate” without know facts, they do demonstrate hate in their speech and mannerisms; they are scarey & exude violence when they speak; it doesn’t matter if you are disabled and a senior (74) like me. They just don’t respect anyone that doesn’t agree with them; their only desire is to destroy that person, no matter their health, age, etc. They HATE! I was at your Port Arthur, Texas Quest Diagnostics Office, today,Tuesday, December 4, 2018 at 3:45 to 4:15, There were only 2 ladies, that I could see, on duty. Should be easy to figure out who they were. My urine specimen was ordered by Dr. C. G. Patel. P.S. I have gone to Quest for well over 20 years and have not complaints about your diagnostic work. I regret have to find other accommodations and ‘never’ to recommend’ Quest again. I really feel ‘nothing’ will be done but I do feel, as a large corporation, you need to know what goes on in one of your facilities.


Miichelle Ledbeter November 30, 2018 at 4:36 pm

Quest is THE WORST COMPANY. Extremely Rude Employee’s! YOUR Company has lost my blood tests


antonette gazzaniga October 24, 2018 at 12:29 pm

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


Edward Eades September 13, 2018 at 11:15 am

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!!!


Unknown July 19, 2018 at 10:06 am

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

I do understand this comment in Illinois it seems supervisors are able to do almost anything to there employees I was with quest for 6 years left because of a supervisor, reported numerous issues, even had staff meetings with the manager nothing was done, and I never received a exit interview my coworkers said my supervisor felt threatened that I was after her job never the case I’m a front person not behind the scenes quest I’m my opinion is almost like a assembly line as long as revenue is coming in and productivity is high the employees do not matter! I’m still wondering what the point of the report line is for there is no action or investigations…between the blatant racial slurs and favoritism I don’t know why I even considered going back


R K February 19, 2018 at 5:00 pm

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!!!!


Erin November 25, 2017 at 8:29 am

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.


Alma October 17, 2017 at 8:03 am

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.


Marie September 19, 2017 at 10:57 pm

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.


Robert Westcott September 15, 2017 at 1:09 pm

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.


Louise Dotson August 24, 2017 at 2:36 pm

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


Joanne Cadman July 21, 2017 at 7:24 pm

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!
