    Do not think you want Physicians to send patients to your lab. I am forced to send patients to TriCore.
    No Lab Request forms online. The Phone system hung up on me 4 times. Two more times I tried Customer Service and also Order Supplies, no one answered and hung up on. Picked random extensions where I get a human, and given the wrong extension twice! Tried to use company e-mail 4 times and refused to send.
    How does a Physician get lab work on their patients with this company.
    Starting to think this company is run by the U.S. Government.

    We need to be contacted by someone in corporate to rectify and issue that’s been going on for months. The wrong insurance (an insurance we’ve never had) was billed for my daughters bloodwork. We’ve been trying for months to fix this. And for someone reason no one at quest can understand why we don’t have an EOB…..well that’s because quest billed an insurance company we don’t have!!!!!! We’ve also gotten our insurance company involved. And they’ve attempted to fix the problem with Quest so they can bill the correct insurance and it still hasn’t been fixed. Apparently because our doctor has an office in NJ that means they billed an insurance carrier in NJ. But the lab work was done in PA. And we see the physician in PA. And regardless….we don’t have a NJ insurance plan. This has been so frustrating.

    I am trying to get my job back with Quest Diagnostics. I had to resign from my job with Quest in 2009, my daughter was diagnosed with Glioblastoma so I had to leave to care for my baby. My old supervisor Antoinette Hudson in Houston Texas told me I could come back because I left in good standards. She told me to apply for a position and when they reach out to her she would like them know I was a very good worker. I have been applying, but no one has called and they have a lot of jobs in( indeed )and everywhere, so I just don’t understand why I can’t even get a call or anything. My daughter passed away in 2010. I not only lose her but I also lose my job with Quest Diagnostics.

  • Tracey Rinaldi says:

    Yes I agree with the above comments, sad customer service, I hope my physician can get my lab results that cost me almost 1000.00$ out of pocket, thanks Quest… what a joke you are, NEVER go to one of thoer labs, wish I knew!!

  • Anna Quartuccio says:

    I have been trying to reach Quest Labs on Old Hook Road in Westwood, NJ for the last 3 hours. No one answers the phone and I need to know what happened to my lab reports since my doctor has not received them. Can you help me?

  • Michael Elia says:

    If you want to be frustrated and treated like a PODS (piece of dog(enter a descriptive noun) **** … ) don’t go to these locations! Don’t call corp. headquarters (1-973-5202700) they don’t answer and the hold programming for the day ends at 9:30am, just like the politicians, you can’t really contact them unless they want you to, or they want money from you. Every avenue to them is designed to thwart you efforts to have someone listen to you … I’ve left numerous emails, surveys, messages all to no avail! lastly(and most importantly I went for testing at the 3000 Q St. Sacramento, calif 95816 on a walk in basis with a web site that states 3 min. walk in wait time- actual wait time 1.67 hours., cut short due to an actual Dr’s appt else where in the building. The staff lead (Jannel (SP) asked if I checked in (I did) or if my name ever came up on the board (it didn’t) or if I had been called to the desk to complete additional paperwork (I wasn’t). She told me I didn’t check in correctly ( the I-pad said I completed check in) I informed her (Jannel) after an hour forty min. of waiting I had an appointment up stairs. I thanked her for the service not received ( sarcastic) and left -The check in mistake on my part( after all who else would be at fault, certainly not them) bothered me so after my surgeon appt. I stopped back in to re-check in and I entered all my info and again it said check in complete. When I tried to inform the staff I was told the only other explanation was I didn’t answer the call of my name -again it must have been my fault. so I traveled 120 miles to get fasting blood work that I was unable to complete (man was my Dr. Pissed) To the company: This is not over after a few days I will shift my attention to blue cross and dignity health (two very large customers of quest) and start my efforts to sway their opinion of quest and the service they (do/don’t) provide my health care providers, one never knows they may be more customer friendly than quest! In any event we shall see what happens. PS if you doubt any portion of this expose’ then try it for yourself 1. call your congress person, see how far you get- next call quest, see the similarities- you can’t talk to quest either! Just in case your wondering- yes I’m mad and tired of being treated like a PODS (PIECE OF DOG SHIT) BTW my sample test kit was two days out of date and deemed(quest) unusable ! hello Dignity Heath and Blue Cross

    • Anna Quartuccio says:

      Mr.Elia, I am just as frustrated and may NEVER go back to Quest. It doesn’t matter what number you try to reach them at, no one answers the phone. Mailbox is ALWAYS full and you can’t leave a message. Why doesn’t someone check on these individual Quest locations?
