Negative star
- - Extremely difficult to speak to a human.
- - Must jump through hoops to reach a human; it's unclear how.
- - Took many calls and a lot of time.
Extremely difficult to speak to a human. If you want to speak to a human, you need to jump through many hoops to get to one and it is not clear how.
I had to find a way to contact a main number so they can talk me through the original menu.
Still had to wait for someone. Took many phone calls and a lot of time.
User's recommendation: make it easy to speak to a human on the first menu

Verified Reviewer |She tried ONCE and said come back
- - Attitude was poor from the start during a glucose fasting test.
- - Only one blood draw attempt; told to return later at 11am, fasting diabetic.
She had such attitude from the start. She tried ONCE to draw blood in one spot then said to come back later.
It's a glucose fasting test. It's 11am. I'm a fasting diabetic.
To try ONE time and dismiss a client patient means you do not know what you are doing so I left before she does damage to me. She was blonde curly hair lady at zip 22408 Care Way

Verified Reviewer- - The online appointment system caused long waits.
- - I had to make multiple trips and stand-by to drop off a bottle.
- - A quick task was slowed by the system.
If I could give Quest Diagnostics a thousand negative stars? I would.
Their appointment system is designed to suck hours from your life, just to save Quest a few dollars cost of a receptionist.
My experience was ridiculous.
This was a simple pick-up-a-pee-bottle, and bring it back the next day.
When I got to their office, they told me to visit their kiosk, and get on stand-by and wait for an hour or two. With no chairs left. Or make an appointment for later that day. I have work. I can't.
I had to badger the worker.
"Just bring me the bottle...please?" It took her about 12 seconds.
Well... Whaddaya know? The wait was apparently unnecessary.
But it gets worse. Way worse.
She advised me to bring it back tomorrow morning...as soon as possible.
Unfortunately? That wasn't possible.
You can ONLY make an appointment on-line at their website. There were no available times when I could get free for 2 days.
So I came back early, as a stand-by. 8:00 AM.
When I got there? The automated system gave me a 10:00 AM time. 2 hours away. Again...standing room only. For 2 hours.
Meanwhile? I had to get to work.
So I took the 10 AM time anyway.
OH, WAIT... THAT TIME DISAPPEARED.
The next available time? Now 2:30.
So- I already missing work. Now, I would have to drive BACK to work- then take off early - And drive BACK to Quest once again...
JUST TO DROP OFF A *** CONTAINER!!!
A human could have processed this in about 60 seconds.
"Sure, I'll take that! Just sign right here!"
Instead? Their appointment system is designed to save them 60 seconds, and make YOUR life incredibly inconvenient. In my case? Making me come THREE TIMES, and spend 2 hours, in the middle of the day. FOR A *** BOTTLE RETURN.
Why? To save about $120 bucks a day... For an office that probably nets (judging by the line) about a 2-4 thousand dollars an hour.
I have run offices. I know exactly what this is. A human being could take care of this in about 30 seconds... Instead, this system cost me (and you) hours and hours, to save them that 30 seconds.
Instead of paying a scheduler/receptionist $120 a day? They make YOU jump through flaming hoops, over and over.
That's about one test worth of profit.
I guarantee you- The owners of Quest are making boatloads of cash. Paying a receptionist would be like throwing a deck chair off the Queen Mary. But they don't. Because they don't care about people. They care about money. Exclusively.
I will NEVER use Quest Diagnostics again.
NEVER NEVER NEVER NEVER NEVER NEVER NEVER NEVER.
Did I say "never?" NEVERRRRR!!!
I hope a tornado blows the CEO's house apart, just so he has to pay the deductible, and wait a year to build a new house.
That seems like a fair Karma exchange.

Verified Reviewer |Disappointing Experience at Quest Diagnostics – 8501 Wilshire Blvd
- - -Waited over an hour past my appointment.
- - -Automated kiosk felt impersonal, like a DMV.
- - -I would hesitate to return and will consider other options.
I recently visited your Beverly Hills location at 8501 Wilshire Blvd, and my experience was both frustrating and disappointing. Despite scheduling an appointment in advance, I was forced to wait over an hour past my scheduled time.
This excessive delay was not only inconvenient but also demonstrated a lack of respect for patients' time. Adding to the frustration, the automated kiosk system created an impersonal and bureaucratic atmosphere, reminiscent of a DMV visit. While automation can streamline processes, it should not come at the expense of basic customer service. The absence of human interaction and clear communication only made the experience more frustrating, especially for those who had taken the time to schedule in advance.
This visit left me with the impression that this location is poorly managed and does not prioritize patient care. I strongly urge you to address the long wait times and improve communication with patients to enhance the overall experience.
Based on this visit, I would hesitate to return to this location for future lab work and will consider other options unless improvements are made. Sincerely, Oliver Steinberg
- It is close to my residence
- Poor management
- Long wait times
- Impersonal experience
Preferred solution: Apology
User's recommendation: I would recommend finding an alternative providers

- - Unable to update insurance info online and cannot reach a human.
- - Website claims updates online, but the change screen isn't visible.
Unable to update insurance info on website and I cannot seem to talk to a human. Website and phone message states that you can update insurance info online.
You seem to have forgotten to make the change of insurance screen visible.
Does customer service have a phone contact number. I have been unable to find it if you have one. I searched for your customer service number and all I get is your automated messages.
I will complain to my doctors office about your customer no service. I will be searching for a company that wants my business.

Verified Reviewer |Resolved: Avoid Quest Diagnostics-Use LAB CORPS!
- - Overpaid Quest Diagnostics by $362 and seeking a refund for 110 days.
- - Moved to Lab Corp, located in Walgreens, with no billing issues.
Company fixed the issue and I have been provided with full refund. After MANY, MANY, MANY phone calls and HOURS on the phone with their billing department, I finally received my refund check today in the mail.
For the love of god, Do NOT EVER OVERPAY this company!
It will take you at least 90 days to get your money back! At least this is resolved now….
For THREE MONTHS now they keep telling me that I am due a refund and that it is coming, but they NEVER mail it to me! Every time I call they tell that I should have it in about 14 days, but there have been MANY sets of “14 days” that have come and gone and still no check has ever been mailed! They simply will not mail me my check back!
I have no issues with the actual Lab work at Quest Diagnostics, but a BIG ISSUE with their BILLING DEPARTMENT! I accidentally OVERPAID a bill by $362.00 and have been fighting to get my REFUND back from Quest for 110 days now!
Even though Quest AGREES that I overpaid them, every time I call, I get the SAME ANSWER, I have put in your request for a Refund. The problem is, the check is NEVER SENT! I have since moved on to Lab Corp, which I HIGHLY RECOMMEND!
They are conveniently located in Walgreens and NO ISSUES with their Billing Department! AVOID QUEST DIAGNOSTICS AT ALL COSTS!
- Staff personnel at bella cruz location
- Billing department
- Over charged
Preferred solution: Full refund
User's recommendation: Use LAB CORP INSTEAD
Lack of communication.... no one to speak to, take the money and run.
- - Phone calls land on recordings and prompts, no message option.
- - Lack of information for tests and poor customer service.
You contact company by phone... location any you get recordings...
and prompts. No place to leave message. Instructions, not enough information, lack of answers for tests, and than the recordings hang up. LACK OF CUSTOMER SERVICES.
If I did not have to get my blood work there, I would never go there and I strongly urge anyone else to go other blood labs.
POOR POOR POOR. Take the money and run service.
User's recommendation: Stay away from, go to another service.

Terrible service
- - Quest makes every step hard and ignores the doctor's instructions.
- - Phone system won't let you speak to a human; check-in is terrible.
Quest makes every step in process hard, and they dont do what the dr asked.
Their phone system doesnt allow you to speak w a human. The checkin process is terrible.
Their waiting room is like a prison cell, with a tv blaring quest commercials non-stop. Ive never had such a bad experience. I cant believe theyre still in business.
I will always choose a different lab. #terrible

Verified Reviewer |Phlebitis injury due to nurse's mistake during routine blood draw
- - Routine Quest blood draw; severe pain and a large needle.
- - Later diagnosed with basilic-vein thrombophlebitis; ongoing arm pain and limited use.
After a week of calling, I finally made progress through the Quest Experiences Department and received call back from supervisor who listened to my story and was empathetic and apologetic and will take action to 1) ensure this negligence does not happen again and 2) give me information for how to submit a small claim for injuries.
This was the worst blood draw experience you could imagine and should never happen if personnel are trained properly and following protocol.
The nurse worked very fast so I didn't have time to react to the very large needle I saw before it was in my arm. I had the worst searing pain and burning feeling when she pulled needle out.
It took me a few minutes to catch my breath and stop my tears.
Pain was so bad around insertion site that night I couldn't sleep even on maximum strength Tylenol.
Next day I told medical professional all my symptoms - searing/burning pain, bruising, extreme tenderness up and down my arm far from insertion site and I had symptoms of a blown vein.
A week later I was still unable to use my arm or manage the pain by maximum dose Tylenol so I went to Urgent care and got a diagnosis of Phlebitis and a better treatment plan including compression and Naproxen.
Phlebitis was caused by Quest nerve using too large a needle - how large? 13-14 gauge by my observation and investigation. As a researcher familiar with needle sizes up to 18G, I went searching for what needle I saw and determined most likely the purple hub, ~1.5mm inner diameter, ~2 mm outer diameter was a 13G. Usual would be a 20-22G.
Now that explains why 2 weeks later I'm still nursing my arm - unable to use my arm at work or home, still taking pain meds. Also I learned from the Urgent care NP they chose the basilic vein which is known to be more painful, easier to cause damage to nerve, tendons, artery that are very close instead of more usual median cubital vein.
Second most frustrating piece, Quest has the worst follow up system for complaints - I made repeated attempts to contact Quest by email and then by phone.
They closed my complaint ticket complaint ticket without follow-up and did not follow up in timeframe they said.
I finally got number of Quest supervisor at the location and she was at first instant that they would use 21G needle and then horrified as I describe my experience to learn that protocol was breached.
Further details now that it's been 2 months and I'm still in severe pain and cannot use my left hand.
3/12 documented poor circulation, swelling, pain in left arm, and weakness, tingling, and cold in left hand
3/13 diagnosis changed to superficial thrombophlebitis after confirmation by Doppler US of basilic vein entirely thrombosed and uncompressible.
Recommended do another 6 weeks of home treatment before I go back in for follow-up.
Follow-up this week 4/24 - still having pain, tingling, swelling, weakness. Severity of symptoms a variable with weather - in heat I cannot use left arm/hand to hold a glass of water, but in cold on better day, I can lift as much as a small glass of water to my lips once.
- Provide lab service and blood draws
- Inadequate training of personnel doing blood draws
- Slow website
- Unresponsive to email complaints
Preferred solution: 1) Apology 2) knowledge that they are correcting the training problem 3) offer of compensation for 2 weeks (so far) of severe pain, inability to use my arm - loss of ~$400 from missing work, $125 cost of Urgent care visit
User's recommendation: If you have to come here for blood draw, be sure to ask them to check what needle size they are using for a blood draw and that it matches their protocol. Do not be afraid to speak up if you feel you need a different person to draw your blood or if you experience an injury.

Verified ReviewerBilling questions are directed to a telemarketing number
- - Marketing numbers block billing questions.
- - Some bills have wrong insurance data.
- - They billed a contracted test; ID was entered wrong.
There are many reasons why I have a low view of Quest Diagnostics:
1. When I attempted to call to question a bill listed on the bill itself, two times on the front and once on the back is a marketing number that will not allow the caller to proceed without speaking to somebody about a medical home device. I had to Google the client services number to speak with someone. This seems very underhanded, and I'm sure there are some consumers that would just agree to the device to get to speak with somebody, only to find out that number can't even help with a billing question.
2. They seem to bill the correct insurance information on some lab work and provide the wrong information on others.
3. They billed me for a test that is actually contracted and agreed-upon not to be billed via the contract with my insurance.
4. The representative I spoke to didn't seem to have any knowledge of another bill which was submitted, and my insurance paid a portion. She kept insisting they only billed one and that it wasn't covered.
5. On the test she did have a record of, the ID number was typed in incorrectly and she kept telling me I was not covered under the insurance.
- Now that i think of any
- Billing incorrect
- Customer service
Preferred solution: Correct and accurate billing as contracted with Regence Blue Cross
User's recommendation: I would recommend you ask your provider to give you options for lab work and use a laboratory other than quest diagnostics
Never answered my question
Nothing has happened. I didnt get an answer to my question. I had to cancel my doctor appointment and reschedule because I couldnt get an answer about turnaround time for my lab results

Verified Reviewer |WORST LAB IN US, AVOID ALL COSTS
- - Lost 5 lab requests and 2 blood samples; delayed treatment by over a month.
- - Corporate admits mistakes but won't fix them; communication is hard.
Quest lost 5 lab request, 2 blood samples, corporate says they correct their self admitted mistakes and do not, they are impossible to talk with, and you will spend hours trying to and following up to correct their gross incompetence. Their screw-up delayed my being able to get treatment for over a month which is one month off my life now, and I am married with children.
Read reviews everywhere, corporate, some employees, company organization and communication are extremely dysfunctional. My experience and my doctor's office is this is the worst lab ever dealt with constant mistakes made, and they do not know what is going on in their own company and systems. Only lab unfortunately which does the test I need, which is why I had to deal with so much.
THEY HURT PATIENTS WITH GROSS INCOMPETENCE AND ARE UNABLE TO FIX THEIR MANY MISTAKES. I beg you for your own sake find another lab if at all possible this company is totally messed up.
Preferred solution: Apology
User's recommendation: Find another lab, they make a lot of mistakes and lose everything
What a joke--can't schedule with these people
- - Voicemails go unanswered.
- - Appointment link on website doesn't work.
- - Calls go to voicemail; no appointment.
- - Cannot reach them to schedule service.
I've left voicemails, not one calls me back. I go to their website and click on set appointment, the link doesn't work.
I call again and get into voicemail *** Can't set an appointment there either. Can hardly wait to see what their service is like if I ever can set an appointment.
User's recommendation: Go elsewhere
My husbands name is spelled wrong so his lab results didnt get sent to doctor in a timely fashion
I. was just trying to get them to spell his name as it appears on his Medicare card so there is no issues with billing. However, I was never able to speak to a real person !

Their CEO makes $14.4 million/year. I’m sure he has multiple homes.
That salary translates to $7000 an hour. I’m also sure he doesn’t care about deductibles. As far as any Karmic retribution goes, he hasn’t wished you any ill-will. Unlike you to him.
Karma will come calling but it will be for you. (I bet you were not smart enough to ask for an extra specimen cup for next time)
Why are you bootlicking on someone's complaint?
