I came here for bloodwork on a Friday. I'm not sure why there's so many bad reviews, but I had a great experience. I made sure to make an appointment so I wouldn't be waiting forever. Once checked in, I only waited MAYBE 10 mins, and was called back. The lady who took my blood was kind and gentle. If you make an appointment, then it's a good experience. read more

This review is for one staff (white & stocky) that can ruin their reputation. I saw my name on the check-in disappeared for a few minutes and no one was calling my name. Other names were being called. I didn't want to just sit there without saying a word. A staff came to the door to call on someone, and I decided to ask her. Instead of calmly listening and explaining the process, she decided to judge me and telling me to have patience. Her comment was just rude and disrespectful. We are adults and many of us have patience. We have been sitting there for hours. We don't need to be told to like a child to sit and wait! These technicians need to be nice, professional, and respectful. They should remove the person's name after calling their names instead of wondering why your name disappeared and they don't call your name in a reasonable time. read more

I never been treated so poorly! I checked in. There board which usually shows once you're in their system was not working. Last time I went I had problems with my checking get acknowledged by their system so I asked some to please check in my name was showing as checked in on their side. Waited for 45 minutes for someone to answer my question. At which point I was told I needed an appointment. Several people told me they've already been waiting over 3 hours. Horrible service! Stay away! Avoid this place at all costs! read more

I have been coming here because it's next to the house but customer service is not great. The staff inside is great but corporate needs to hire someone to work the lobby . You check in and stare at a screen. I had an appointment and was there early. 'My name just disappeared. I ask the guy and he said yeah just keep waiting. These poor older people need help and nobody working can help. The list doesn't work and then you have to harass every phlebotomist that comes to do their work stop being cheap quest read more

Unfortunately, I didn't recieve the name of the lady "helping" me with my scheduled appointment. She was incredibly rude and disrespectful. I've had successful trips to Quest Diagnostics before, but this was by far the most waist-of-time experience. I had a scheduled appointment and still waited an hour. By the time I was seen, I wasn't able to complete my labs and the service worker just sat there when I asked for a solution. This is the most convenient location for me, but I will be refusing care from this specific worker. read more

Disgusting patient care, dirty facility. None of the sanitizer stations are operational.

This review is specifically for the staff, every time I come here they are so rude. This last time the older gentleman, which I e never seen before. If you don't like serving people, get out of healthcare! read more

No there very rude Specially person in charge at time Just gave me a horrible time As is ur fasting u don't feel ur best And to be treated wrong is the worst . read more

This location is extremely disappointing. I understand prioritizing patients with appointments, but making walk-ins wait until the end of the day is unacceptable. A well-run facility should be able to incorporate walk-ins throughout the day. The lack of customer service here is concerning, and I would not recommend this place. Quest management really needs to review how this site is operating read more

If I could give this location zero stars I would. I had an appointment for 1:20PM to get some bloodwork done per my doctor's orders and following the instructions on the confirmation email, I arrived 10 minutes early to check in at the kiosk. I check in, scan my ID and insurance card and the machine tells me I'm number 103, to take a seat and wait to be called. I do so. I did expect to not be seen at 1:20 because realistically when are you ever seen on time for any medical appointment, but this was ridiculous. I had an appointment and waited over an hour. People who arrived easily 30 minutes after I did, were seen before I was. I looked at the screen which had all the appointments on display and the order of walk-ins to find that my name isn't showing up. After waiting over an hour, I just left. There is NO ONE you can ask for help or ask questions to because they're all behind a locked door. There's no window or desk to inform someone you've been skipped or ask a question. As if that wasn't bad enough, I had been fasting since 9AM (1:20PM was the earliest appointment I could get). What's the point of making an appointment and checking in if the damn machine isn't going to check you in? If my appointment was cancelled I have NO idea, because there was ZERO communication. Wasting time on my ONLY day off this week was not something I wanted to do today. Now I have to go to different location NEXT WEEK (on my ONLY day off) pushing back all my medial care just because of the ineptitude of this place. This location and its staff are a JOKE! read more

I really liked it here. I wanted to dislike it because of the low rating but it's hard to dislike. I walked in on a Monday afternoon as a walk-in and had to wait about 45 minutes. They have a screen available to see how many people are waiting and how many people have appointments. This place is very clean and the staff was amazing and friendly. I think the worst part was having to wait, but I did not have an appointment so I expected to wait. It's very clean and the staff is very nice so considering they are doing us a service I highly recommend this location. read more

frustrated. Came to get blood drawing at 7 am when the doors opened. There was only 4 people appt and 2 walk in I'm the 2 walk in. Now this place is packed. No sitting room 10 walk ins and none of us have been called. Manager needs to improve the way patients are seen. get 5 appt and 1 walk in things will be smoother instead they have NOT called in 1 walk in 2 hours. I understand making appointments is a better way. But when the website kicks you out you're unable to make an appt. So then try to call and they keep saying you need to make an appt online. This not the first time. At this location in Fontana. Staff doesn't even want to help or listen. I used to live in a different county and that quest office was on it. Every 6 patients they call 2 walk ins. Wish that the office wasn't so fare Update now it's 10 am and their saying no walk in will be seen until after 11 am or longer BS Only 1 Star because place was really clean read more

Staff needs training in customer service and efficiency!!!! No value and no goal for patient satisfactory. Scheduled appointment is useless you wait for hours. Staff takes their time and just chit chatting on the back just don't care about patients. This place is horrible......employer needs to look out for the employees they hired. Complaining to corporate as well. So if you feel the same way contact the corporate as well about this branch. read more

Horrible customer service, not organized, and a waste of time. I booked a basic bloodwork appointment a month prior and when I arrived there were 10 people in line to checkin to the minimal 2 kiosks. By the time I checked in it said my appointment had been cancelled because I was more than 10min late; seriously?!?! No one came out to call my name. No separate line for people who had appointment. And no instructions told me I would need to show up 20min early. Plus this was 10min after the opened. Other people in line were saying similar things that this location is horrible and don't waste your time. read more

Even with an appointment, they ran about 30 minutes late from my time. Lady who took my labs had me wait longer at her station as she stepped away for a personal phone call. When she returned, she was very rude and demanding and also left my arm bruised as she just shoved the needle into my arm rather aggressively. Will not be going back. read more

My 4 year old son had an appointment on 08/16/2024 , there were so many things wrong at this location . First we waited over 30min to be seen, once they called us to the back, the technician was awful, she was very rude, and to top it off she poke my son and started looking for the vein once the needle was inside. I couldn't believe it, I had to tell her to stop! My sons arm was left with a huge mark and bruise. Totally dissapointed. And to top it off there is no one to talk to, there is no such thing as a front desk at this location. The technicians call the patient and type in all the information on the computer. Please don't come to this location. You will be extremely disappointed. read more

I highly recommend booking an appointment because the room fills up fast with walk-ins. I had an appointment at 7:20 am and I was out within ten minutes. read more

Why do they insist on taking people 10 min before there appointment time and not take a walk in. They need to improve.

This lab moves extremely slow, I waited almost 2 hours as a walk in. I don't recommend this location.

This is the second time me going to this location. The first time was good. The girl was very kind. She called my name correctly. She verified the doctor. There was one test I couldn't get done because she said it had to be done in the morning . I came in today to get that test done when l was called in phlebotomist pronounce my name wrong so just ask did you mean Jeannette and the phlebotomist answered it could've been Jeannette, but I saw Janet. I don't have my glasses on today you'll have a name different name today. She didn't asked what was the name of the lab that I was getting and I told her I couldn't remember and then she asked who ordered this lab and I honestly I couldn't remember who ordered it. I was getting a lot of test done it could've been my dermatologist. I honestly couldn't remember. I just know that the previous phlebotomist had placed that lab on hold then the phlebotomist of today proceeded to scold me that next time I need to know the doctor's name she's very rude. You could tell that she was mad or upset about something total different experience from the first one. I think the only thing good I have to say about today was that I did come in without an appointment and I did get called in pretty soon. read more

Make sure you look at your EXPLANATION OF BENEFITS!!!!! They're trying to charge me $81.12 when I actually owe $16.21!!!!!! I'm on hold right now (as I type this review) the recording keeps telling me 10 minutes and I've been wait for over 30! This also isn't the first time we've had issues. I've been double charged or overcharged by this establishment! read more

2 stars for being so close to my home. This review is from over a year ago but I wish I would have looked at these reviews before coming here... I tried giving this place a few tries since I have blood work done often but it's just not worth it. The last 2 appointments I had blood drawn was with the same phlebotomist the first time she hurt me but I figured I'd give her another try maybe she was new at this, the second time she literally stabbed my vein! I had a white sweater on that day and when she was done I put my sweater back on and I started feeling something going down my arm and I look and see I had bleed through my sweater. I told her I was bleeding through so she tried applying pressure and she couldn't stop the bleeding I was there maybe an extra 10 minutes waiting for it to stop. That was the last time I ever went to this location and now I have a scar in my arm. read more

TERRIBLE attitude from nurses. They couldn't care less and send you off with "they look fine", when they "checked" my niece for an ear infection they said she "looks" fine. not even 72 hours later she had to be rushed to the hospital for surgery on her ear smh read more

What is there to write this is a pretty much self-service.. They don't even greet you when you come in the door And if you have an issue there's no one to help you they stay behind the locked glass door... Even fast foods that have kiosks are more helpfull welcome 2 Thunderdome And the Era of laziness... Also since we have to do our own Check-in maybe you could put a little table next to check in station so we can put our stuff on it while you ask for a Driver's license and insurance.. Back in the day receptionist had a desk. read more

I reviewed this place before when they had someone to talk to, but now they have made it all kiosk. They have not changed, so if you don't have an appointment, be ready. I repeat, be ready to spend all day waiting. I will compare this lab with Lab Corp employees because quest lab employees sure take their sweet time getting patients in n out of the place as to lab quest are really quick even if your a walk in and that is how Quest diagnostic employees should be. It shouldn't be hard to take blood. So I suggest Quest Diagnostic get there act straight and find another way to make all patients appointment and walk ins feel like they are important. read more

Terrible customer service! Suggestion: Provide clear instructions on what a patient should do once they enter the room. Consider the fact that there are people of all ages and levels of understanding. read more

With appointment, it's so simple and quick. Staff checks everyone for temp. Socially distancing everyone. I was early for my appointment but they were able to take me in earlier. That was great. Friendly staff checking insurance info. And just very organized. Last time here got my lab results next day; my doctor called me and I was so surprised. Highly recommend. Appointment appointment appointment. read more

Sierra Lakes Lab Quest Lizeth was so kind and patient with me ! I walked in without an appointment and waited about 10 minutes. I tend to feel dizzy/nauseous while having blood drawn and Lizeth made it a quick and painless experience. Thank you !!! read more

This location is very slow and checking in is with a kiosk. It's very unfortunate for elderly people who don't know how to operate this kiosk. What happens to dealing with a real person nowadays? Unfortunately, this is the real world and process . No help for the elderly at all. I'm here because of my Mom and definitely will not choose this insurance for sure read more

I showed up without an appointment as I usually don't schedule one but during covid 19 there are some changes which was no problem as they were nice enough to see me without one. Wait time was less than 15 min., & they were amazing with drawing my blood and talked me through every step whike asking if I was okay.. They were very pleasant and kind. I see a lot of people with complaints but I had no problems and the experience exceeded my expectations. I've been coming here for years for lab work. read more

Quest Diagnostics - Building and main entrance for quest diagnostics - Laboratory Testing Near Me - Fontana, California

There is no front desk here anymore. The employees are all literally behind a locked door. I've never felt so unseen at a lab, and I've been to many throughout my life. This place might be sufficient if you have an appointment, but if you just need to pick up collection supplies or drop off a specimen, you'll have to wait in a giant queue. If you have any other option for a lab, don't come to Quest. read more

Quest Diagnostics - No front desk. No employees to greet or help you. Good luck - Laboratory Testing Near Me - Fontana, California

I just left this lab and was sad to see the attitude and demeanor of 2 of the staff here. They spoke rudely to many as if we are deaf, and dumb. Repeating themselves and constantly speaking harshly, this is not the way to treat patients. I have worked in customer service and guest relations my entire life and this place would definitely benefit in RE- training. We the patient already don't want to get labs done, so it makes it worse when staff is unhappy, slamming down the printer machine and speaking down to you. The young girl Miriam was the only one I noted to wish the patients a good day and had a smile on her face. Maybe they are overwhelmed, could be alot of factors but get it together, please. read more

This place is ridiculous, why make an appointment & still have to wait an hour , then they say theirs only 1 person to do the draws .. wth really . So please take a lunch & use the restroom while you can . Insane really read more

I have been to this lab on 3 different occasions now. Each visit has been a good one. Checking in is a breeze, they have 2 tablets on the front counter. All these tablets ask for is "your name, phone number, and dob". The process is a quick one, I'm usually in and out in 2o minutes or less. The lobby is nice and big, and very clean. Not to be outdone is the staff, they are very friendly. read more

Quest Diagnostics in Fontana on Sierra Lakes Parkway, the girls that work there do not know how to draw BLOOD, they destroyed my Vein today October 28, 2020, posting picture of how my Vein looks , picture is at 3:30 my blood was drawn at 10:30 today. This is the second time that my vein looks like this, happened on June 16 2020 after going to Quest in Fontana. I have had a lot of blood work drawn in my lifetime never had this problem ..I think Quest needs to send their Girls to get training on how to draw Blood read more

Had appt today @ 9:20am! Took day off of work to get blood work done! When I arrive, there is a note on door that they will be closed until December! I have conformation email with number, date, and time!! How hard is it to send an email or text? Total waste of a day! read more

Horrible service here, long wait times. They try to squeeze as much people in a day then take their lunch and leave people waiting for hours. (4-6HOURS+) workers here are very unprofessional and rude. I demanded to the worker I wanted to talk to a supervisor and the supervisor isn't even on SITE. Instead they give you a number to call and contact a supervisor (which doesn't answer the phone call). Service here at Quest Diagnostic is pathetic and plan to be here all day when coming here. read more

Band around my arm was very loose so my veins didn't pop out like they usually do. Nurse proceded with a Hail Mary and surprise barely any blood came out. So he pulls out a little and wiggled the needle. I got so close to slapping the shit out of him but I held it in. Pulls it out and forgets the cotton ball so blood squirts all over. Then he performs another Hail Mary, he got lucky this time. Quest clearly scrapes the bottom of the barrel when hiring or has little to no training. Good luck if you use this office. Other reviews about customer service are usually on point. read more
