Quest Diagnostics Complaints & Reviews

Quest DiagnosticsLab tech did not want to draw the amount of blood ordered and left out some labs that were order.

I went to a quest lab to have my labs done. I had a very tall order of labs requested by my physician. It was recommended that I split them up in two days. So half of my labs were drawn on January 31, 2021. I made an appointment at another quest lab location( East 36thSt, NY, NY) to have the rest drawn. When I told the lab staff there that I'm here to do the second part which was highlighted, She rudely and loudly stated, "I'm not doing this" after she saw the amount of labs to be drawn. She told me I would have to go back to the lab I had it drawn at initially. I was so disappointed that I was refused service by the staff. However, I went back to the Quest lab I had the first set of labs drawn on January 6, 2021. Even more disappointing is all the labs were not drawn. I didn't even know that until I had a follow up visit with my doctor. This is the worst lab ever, I would never go back. I consider labs very important and should not be carefully reviewed so none is missed. A missed lab can cost someone's life. I will go back to the lab I used to go to. In addition, I made a complaint to the Quest labs but received no response. So frustrating! Never again.

        Quest DiagnosticsDriver

        I'd like to complain about your Quest Diagnostics driver of vehicle 40004 in Ft. Lauderdale, Florida on Federal Highway at 3:20 on January 19, 2021. Speeding, weaving in and out of traffic, tailgating me while blowing the horn. I'm a doctor on vacation in Florida and not pleased to see this radical driving behavior by one of your drivers.
        I would hope to see this matter addressed. Unless you allow irrational drivers driving a company van with Quest Diagnostics on the written on the side.

            Quest DiagnosticsTest result

            I had a covid test on July 14. I needed a negative to see my father, as it turned out, before he lapsed into a coma and subsequently died. I received a 'result' that stated that I had failed to submit a second ID with my sample (despite following all instructions), but the test would be processed anyway.


            Specimen labels must include two forms of patient
            ID. Only one unique identifier was present on the
            sample(s). The testing you requested will be
            processed; however, going forward please provide
            two identifiers as required by the College of
            American Pathologists (CAP).

            My specimen sample is: GB495850K

            I corresponded with your organization several times asking for a 'negative' or 'positive' result, and the only sensible reply I received was a copy of the result saying that the test would be processed anyway. I have not received any kind of acknowledgement that the test was actually run as was stated or what the result was.

              Quest DiagnosticsWellness Test / Blood work

              I've been pushed around for a year now, trying to resolve my situation.
              In short, because of the test I got in November 2019, I ended up at the emergency room, my arm turned black and I was in unbearable pain that didn't let me sleep and work.
              I got a bill that mostly covered my insurance. All I asked is the rest of my bill to be covered.
              The person that promised to help me resolve the case was
              Sheryl Stanley [protected]). After leaving her several voicemails she never ended up returning my call.

                  Quest DiagnosticsTimely lab results

                  I had a lab drawn on October 30. As of today, results were still not available to me online or on the app. Ten days is too long to wait on test results that they have. I called them and they were very nonchalant and unconcerned about this problem This is the second time in a row this has happened to me. The lab I had drawn on October 1 took just as long to get to me. IT seems unimportant to get the lav results published. MY doctor's visit can't be scheduled until I get my lab results.

                    Quest DiagnosticsCan't schedule an appointment

                    I have tried to schedule an appointment with all locations in
                    Chico, CA through the online appointment ap. No response. I have called by telephone all locations, can't get through, just the opening jargon, then the line goes dead.
                    I have called corporate headquarters, got through, but a ridiculous wait.

                    Someone needs to do something about this. Had to schedule an appt with
                    a different source to keep my dr. appt. You need to fix your problem quick.

                      Quest DiagnosticsDriver was reckless

                      On October 3rd, 2020 at 3:53pm. A quest diagnostics driver was behind me on 6th street In Berkeley California, until we reach the light to turn left onto Dwight. When I pulled into the left lane to turn onto Dwight, I stopped at the light because the left arrow was red. The driver of the quest diagnostics car stepped on the gas and drove around me, getting into the lane that had the green light to go straight. The driver drove into the intersection as if she is going straight and made an legal left, without hesitation of on coming cars. This was a female driver, who looked short in the driver seat. Possibly from the Hispanic or Asian race. Not Caucasian or American. When the driver saw that I had my phone out they quickly slowed that and at the next light when I was turning right they looked at me with worry knowing they were in the wrong. Please have your employees drive safe and think about others. If they are late please remind them to leave early. Thank you.

                      Driver was reckless

                        Quest DiagnosticsQuest Diagnostics Website

                        Prime example of "Let's make everyone jump through hoops and put customer service as far away as possible so that nobody gets through to help desk." Their call line will try to not get you to help desk if you say you're a patient with a web portal problem. You have to say you're a healthcare worker and get redirected... Their website is broken on mobile, Chrome, and firefox... help desk was genuinely surprised I got through to them and obviously was no help. Advice was "just send a message to help desk and wait 48 hours"...I'm literally on the phone with help desk!!

                        Long story short: don't bother trying to look up test results online with them because their identification verification doesn't work, which forces you to send a message that they may or may not get back to you on. After all the trouble... you'll probably have your test results anyway.

                        Advice: don't use this company if possible.
                        - Incompetent/miserable IT department.
                        - Try to make it impossible to reach someone for basic issues.
                        - Broken website that makes you input all your information about yourself... but can't use it. It's scary when a website that can't even function makes you put in your SSN.
