If an older person did not make an appt, they may sit for hours. The check-in is confusing for older folks and the technicians can't help because they are being timed on how many patients they see. Quest is not Healthcare, they are Wealthcare. Shame on UH for hiring them.

Too much bruising
Too much bruising - seems like employees are miserable…

Poor people skills & bruise
Young lady was not friendly and thought I was mad at her for wanting to confirm the lab orders from 2 different doctors so that all the tests were accounted for. Everyone should do that and the lady should have welcomed the customer's oversight. She also left me with a bruise and the 'draw' was painful. The overnight results are appreciated but more training is needed for staff. She was well-groomed and her make up likely took hours, but I'd prefer better people skills

They closed the receptionist window
Very disappointed with my experience.
They closed the receptionist window—there is no human contact at all anymore. Everything is pushed to a machine, and it’s simply not working. While I was there, three other people (besides me) had to leave because we couldn’t get our questions answered through the system.
I waited, tried to speak with a technician, and unfortunately he seemed annoyed and was not helpful. In the end, I had to leave without getting what I needed—and now I have to go back again.
Please bring back some form of human interaction. Not everything can or should be handled by a machine. People need to be able to ask questions, especially when something isn’t straightforward.
This experience was frustrating and unnecessary.

overbilling, bad customer service
Yet another medical provider that bills for "laboratory services" while hiding what tests they are billing for. 30min on the phone with the customer service rep, she insists that they in fact did different tests, but the bill has the same line repeated multiple times. Looks like overbilling.

Inflammation and 30% of blood test items not obtained.
I have had itchy inflammation and possible swelling at the place on my arm where the blood was drawn. The results were prompt, but about 30% of the items stated, "Result canceled by the ancillary," (vs. I've read 3% is normal); Google says that means: "often a problem with the specimen's collection, handling, labeling, or order, rather than the lab analysis itself, leading to an unreliable result. Common reasons include insufficient sample, mismatched labels, tampered seals, wrong patient, or duplicate requests, requiring a re-collection or new order for accurate results." The digital check-in in the waiting room was fine. They should let patients know in advance where the only door in the large building that is unlocked on Sat is located behind building.

⭐️⭐️☆☆☆ Disappointed With Service at Quest Diagnostics - Laguna Paseo De Valencia
I scheduled an appointment for 10:00 AM and arrived early at 8:30 AM, hoping to be seen ahead of time if possible. I checked in with staff, but even after waiting past my appointment time, I was never called in — and then I noticed my name was no longer on the check-in list. When I asked another representative what was happening, he had no idea why my name disappeared and couldn’t give me an explanation.
I explained that I had been waiting and needed to use the bathroom for over an hour, and was just trying to get everything moving, but it seemed to upset the staff member. Then a person named Bahar came in — without introducing herself, identifying her role, or even wearing a name badge or professional attire. She didn’t apologize for why I was dropped from the appointment list. Instead, she told me I needed to apologize to a lab tech or she would refuse service, which felt narcissistic and unprofessional. After I apologized, she left without addressing the real issue or providing clarity.
I finally asked the tech for her name and title, because I was very disappointed by how I was treated — it felt like I was being scolded like a child for something that wasn’t my fault. There was no valid reason I should have been told to apologize, and no explanation given why my appointment was mishandled.
Overall experience was frustrating and unprofessional. I would like management to be aware of this.

Quest location at 3620 Sheridan Drive…
Quest location at 3620 Sheridan Drive Ste 100, Amherst, NY 14226.
This lab is commonly slammed with patients. Even with an appt, wait times might exceed an hour. Forget about walking in without an appointment at the wrong time.
In winter, the office is dingy and cold, the floors are dirty from salt and grit. No wasting corporate $$ on removable carpet service.
The parking lot is very small and shared with a busy medical practice and furniture store. It’s an accident waiting to happen.
There is no easily accessible patient bathroom so prepare for that ahead of time - no frills here.
Make SURE your MD has submitted your blood work order before you go to the lab.
That's not a Quest deficiency but it will make your visit MUCH worse if your order has been overlooked by our own MD.
My empathy for the phlebotomy staff is deep. They are clearly understaffed, underpaid, overworked and stressed out but marching on - please be understanding and nice with them.
An ironic video of the archetypical 60ish bald, sardonically cheery Quest CEO who made $15 million in 2024 plays in the waiting room on the TV with the appointment times and patient status.
No way around it, the Quest experience at this location is not good and I get to go back again in less than a week.
My FP’s office didn't enter my blood work order in the Quest system despite the fact his group is directly affiliated with Quest after his group sacked their own group of 22 lab techs and lab services employees on 01/01/26.
If only the Quest CEO and his hedge fund cronies focused on patient satisfaction rather than earnings per share for just one month per year things might be different.
If they did care, perhaps an appointment at Quest might feel more like an interaction with a well run medical establishment and less like a visit to a plantation.
But shareholders definitely out rank employees and certainly patients at Quest.
