I’ve been to this location many times because it’s close to my house and I always say I’ll never go back. This time, however, I’ll never go back! Every part of this place is dirty and disgusting and they don’t manage time well.
This last time I was there, I had 11 vials drawn. The technician, Griselda, took 40 minutes to input info into the computer and print out labels while I sat in the freezing cold room. Seriously ridiculous! She even went to get an extra ream of paper while I was sitting there waiting. She wasn’t out if paper! When she drew blood, she poked me very hard for no reason. My vein is always easy to get. When she switched the vials, she did not hold it steady and it was very painful. Then when she was done, she reached way across herself to get a gauze square, moving the needle even more! They have a VERY BAD SET UP! One of my vials almost rolled off the counter. What a nightmare!
This morning I went to the Upland location for blood work and the set up is SO much better. The technician has everything close at hand and was very efficient.

First of all this place is located in a maze. There are two buildings in this plaza (same street number) and this one is located inside the ‘medical’ looking one although there’s no sign at all outside of the building.
My appointment is at 11 and I’m 10 mins late trying to look for this place, the lady at the front desk looked into her computer and up and said ‘you are late, it’s 11:10. I’ll need you to go over and sign in as walk ins’ with the WORST attitude.
fine, thank god i didn’t have to wait for too long… and then the nurse had to poked me twice to find my vein… a week later now i still have a huge bruise on my arm…
this location is close to home, but maybe i’ll drive a little further in the future if i need my blood works done!

Started coming here the past month as my daughter needs to get constant blood work done. I only like the fact that it is located close by but customer service wise, not too happy with the poor service we have received. For example, I was trying to call in to check if they had received my daughter neurologist orders the other day before coming in the next day. It had taken me over 20 mins to get through the phone!!! That’s just not ok at all. The actual techs that draws the blood are friendly but not the front desk staff. They act like they always have a bad day. Just bitter all the times.

This company and or specific location is unorganized and does not clarify before making appointments. My suggestion is to call twice and verify exactly what is required of you as a patient before arriving.
I came to get an independent drug test to ensure that I would be cleared before applying to jobs. They made an appointment, set a date, sent me to an office 25 miles from my home. Then when I arrived I was told that it must be a dr ordered or company ordered test. I was sent home with nothing collected and half a day wasted.
Get your facts straight.

Worst customer service. .came to drop of a specimen and had to wait 40 minutes. The lady at the front counter kept repeating the same thing… sign your name and wait! I’m not here for a test just to drop it off… give me a break!!!

Really friendly staff, I’m so use to poor customer service that I usually expect rude customer service. But I was shocked that they were actually friendly and helpful. It’s very clean and very organized as well. I was in and out of there in no time!

I come here every year to get my wellness exam and blood work done. They are always busy so I usually set up an appointment ahead of time. Today, I came in without and appointment and when I got here I was told the wait was 45 minutes. Which, I thought wasn’t bad. So, I signed in at 9:15am and the lady called me back up for verification and 9:30am. The office is clean, from what I observed during my wait. The staff appeared efficient and busy, unlike most clinics or doctors office I have been to. I’m curious to see if they are as efficient as they appear… And if all goes well as planned, the visit shouldn’t take any longer than 10 mins. So let’s see if they can get me out of here by 10:15am!

I’ve been coming here for 6 months now, and I have yet to meet any associates who were rude or unfriendly. For a 7am start, they are very friendly! Even on Thanksgiving eve, I was in and out in 30 – 40 mins or so. I really appreciate the early hours and hassle free service. I’m sure they get busier during the day, but that’s expected with the number of people they serve.

Omg. So this place is designed to be a health care and drug testing clinic. Simple enough. But the first two people I see behind the counter are beyooond obese. Honestly, presentation matters. If you were selling doughnuts this would be acceptable, but for «health care professionals» I find it to be a bit repulsive.

Went to this location this morning for routine lab work. My appt time was 9:45a and the wait time was less than expected but I had an appointment — thank goodness — because the place was packed. The front desk was friendly and efficient. The technician who drew my blood was nice but very robotic. When she was done collecting the last vial she rattles off instructions on how to leave a urine sample and hands me four packets of «cleansing» wipes. Really? I ask her if I need all four and she says «yes». Well, after using two I was done and when leaving I left two packets at her station and was about to step through the door when she asked «you didn’t use all of them»? I said «no.» She said «the sample will be wrong because you needed to use all of them.» I looked at her like I had a big question mark on my face and she continued «the samples change and that’s why we give you four wipes to get a more accurate reading. Do you want to give another one or do you want to go with this one?» What-the-Heck? I replied «I’ll go with this one.» I wished she would have offered this explanation in the beginning instead of handing me a fistful of wipes and saying «use them all.» By the way, she threw the unopened wipes in the trash can (so wasteful).

Finally after visiting for the fourth time, they told me they did have my info from my doctor after them telling me their fax machine was broken. Apparently they had it the first time and they told ME it was my fault and I confused the lady so she didn’t know where to look… What kind of customer service is that blaming a customer. This place does not know what they are and and their fax machine is still broken too so your doctors won’t be able to contact this location directly. Just glad I can finally get out of this place…

I would recommend going to a different quest location. I have been there 5 times and 4 times they have screwed something up. They type the wrong code or they lost my paperwork that the doctor sent across. The inside smells like food and the bathroom is filthy. Good luck if you deside to go to this location off Roswell.

I made an appointment to have lab drawn today. Got there 5 mins before. Their computers are down and told me that they can have another facility fax them their orders. Waited 30 mins, then they call me saying they can’t get a hold of my doctor to get orders. Why tell me you trying to call another facility when all they did was call my doctor. Then they offer me to schedule an appointment at a different date. Horrible service. Poorly managed. If this wasn’t my nearest location and my insurances covers other lab companies I would not be here ever again.

This Quest Lab is Clean, organized and the workers are very efficient! I was impressed and will definitely come back to this location.

I always make an appointment online before going and it is so easy. I’ve been to this location probably 4 times this year for blood work and I hate needles so keep that in mind with my review.
I have a new doctor that does the lab work at their office and I have never been so bruised! Next time they request lab work I am going to ask if I can go to Quest. Seriously, this quest location is almost seamless, no bruising (or pain) and everyone there that I’ve had contact with is nice.

Routine lab tests without an appointment can be a short or long wait depending on how busy they are. I would recommend coming in as soon as they open to get a quick walk in visit.
I like this location because for glucose testing, even if you don’t have an appt, you get in quick. They do have lunch hour at 12pm so be sure to give ample waiting time for the glucose test (1hr/2hr/3hr).
My current visit is on a Friday morning. Since 8 am today several walk ins came in and out quickly. I’ve also visited on a midweek afternoon and waited over an hour.
