If I could leave no stars at this Quest, I would. One of the lab techs in the facility, Teresa , is extremely confrontational and disrespectful not only to healthcare professionals who are dropping off lab work for patients, but the actual patients that come into the building. She is condescending towards patients and speaks very low to them Including and nurses that come in to deliver blood. She has a very rude tone of voice when speaking with her and will deliberately make you wait longer. If you come to this lab, be prepared to be spoken to like a child. They also never have their ducks in a row when it comes to dropping off lab work. They misplace paper work , they don't check people in correctly, and they basically tell you you're SOL if you don't have everything in line. Extremely unhelpful and lazy. I waited almost 45 mins once just to drop off blood!! Teresa Jeffers also criticizes and belittles staff in front of patients, out in the open where everyone can hear. It's embarrassing. She will answer your questions with questions which is very disrespectful as well. She speaks to everyone like they are children and acts like she is allowed to speak to people the way that she does. She is loud and obnoxious. read more

Came in today as a walkin for fasting labs. Arrived at 7:45am they open at 8am I was like 9th person in line. Once they opened the doors everyone signed it they called you up individually to get your paperwork and insurance card info. It took about an hour total but at least the Phlebotomist was good and didn't hurt me. read more

This site has the worst service. They take appointments but don't stick to them. They don't take first come first serve and are all over the place. I have been to several locations where they are just as busy and provide great service. This North Fontana location is by far is the worst read more

Save yourself the disappointment. This place is an embarrassment. Teresa was extremely rude towards me, patients and other health care workers. She is loud, unorganized, disrespectful and condescending. I work in customer service and am held to high expectations but I am also a human being who is kind to others because I treat people with respect. Not her.. she talks to you like you're a child. Never going back here for blood work again. read more

Went there early doctor asked me to go first thing in am Got there at 630 says don't open till 7 on window But some one walked in so I did walked stairs in brace on foot got to top! Told next week they don't take walk ins and will be by appointment only next week? And they don't have any time the place was empty so walk back down stairs thanks for the kind helpful service wow??? read more

Worst experience ever. I made a mistake on the date of my appointment. Since they were Completely Empty I asked since my paper was already there could they please see me as I had a doctors appointment Monday. Get this again there was no one there and the parking lot was almost empty, I did see people go into urgent care next door. I asked please several times and the woman in the chair went and asked Dontisha who took one look at me and said no with a laughing voice behind the mask. I asked since no one is here could you please? No. No. No. Of all the complete conceited asses this woman takes it. This is the way of it today. Absolutely zero respect like people are raised in a slum yet quest hired this probably to fill some quota. I won't come back. Dontisha if your reading this go jump in the fiery pit. read more

I seen Amanda today. She was great! Normally they have a hard time finding a vein and leave bruises. She found a vein and I didn't feel it! I would definitely say she's a Professional at her job! Thank you!!! read more

I came to get bloodwork done here, when I arrived I was checking in. The receptionist was so rude when she asked for my insurance card. She started snapping her fingers when I was looking for it in my purse. I wanted to tell her to stop being rude but I just ignored it. I swear this was the worst receptionist ever. I will never ever come here again nor recommend anyone going there. If anything , try going to the one on Lemon Ave. They are more professional read more

No stars whatsoever to see the pictures and you will judge by yourself unacceptable no no no!!!!! read more

See all

sooooo slow......and rude. The worse thing you can do is ignore people and act like you don't seem them. Yep, you'll get that here.

My family and I have been coming to this Quest since it's the closest, always had an appointment. I completely understand that everyone is understaffed and I sympathize with workers. However, the amount attitude these workers have towards everyone that walks into this facility, appointment or not is unbelievable. I've witnessed elderly people walk in and are clearly lost and unaware what to do and get short rude answers. Patients who are rude deserve that kind of treatment but don't dish it to everyone else that walks into your facility. I've had to go to other Quest recently due to limited availability of appointments and those Quest are also understaffed but the staff has always kept their composure and still managed to be cordial and helpful. Never coming back to this location. If you come here except to get rude attitudes and unhelpful staff regardless of whether you're nice to them or not. read more

Honestly, I have been going to this office for years. I always have good service. Anyone wanting to avoid a long wait can make an appointment, which diminishes wait times, greatly. The staff here takes their job seriously, and I appreciate it, because getting blood drawn is no fun. read more

These people like to argue and fight with patients. Went to have labs drawn and the lady wasn't nice or gentle at all. Then they wanted to argue with me about paperwork and insurance. The girl in Cubicle 1 needs to be retrained on how to deal with patients. If u can go to another facility . read more

Drove my grandma to check in for her blood work. They said we would receive a text to check in. We waited 10 minutes and no text. When we walked in they said she would need to reschedule because she was more than 10 minutes late for her appointment. WTH? read more

Worse customer service that I have experienced in my lifetime of getting blood work. Very rude to elderly people they took so long to call people a lady asked they can have a chair for the elder people that have been standing for so long the technician rudely said "no". Someone in charge needs to do something as how people are being treated. I will no longer come to this facility! read more

This is the worst inefficient lab place EVER! For walk ins they took 1.5 hours to ask for your lab work and then proceeded to tell me that my labs would take 2 hours and they cannot accommodate me! If they didn't take 1.5 hours to ask for lab work then I would've came back early in the morning. They are lazy and inefficient and slow! Do NOT come here for labs! Go to the Quest Diagnostics in Upland off Mountain ave. it's the best place to get labs! You are in and out!! read more

I have been coming here for about a year. I come every 3 months, unfortunately. With that said, this is a great location. Place is always clean, receptionists are efficient, wait time is relatively short; I've never waited over 20min. And, technicians are kind, efficient, and seem genuine/personable. There is AC that keeps the area cool, and plenty of seating. Highly recommend to anyone looking for a Quest Diagnostics Lab. read more

All current reviews are 100% real; and generally I trust Yelp enough to either do business with said company or I can somehow manage to give them a chance based on the type of industry the business is in etc. In this case, I decided to bypass Yelp reviews and go for the kill assuming that no one likes waiting reasonable wait time or getting blood work etc. PLUS I live right down the street, so this is local to me. HOWEVER; the actual wait times were horrible! I arrived around 9:30AM and left nearly around noon. I did not have an appointment, and I was fasting so I had no choice but to swallow it and wait. I waited, and observed how inbound customers were treated, and sadly to say it's bad! Bad customer service, it's certainly a rude approach to everything. "There's a sign here, stating so" -- "Your doctor should of told you" -- "Your doctor should of told you our hours" and so on. There's no customer service in this place when it comes to greeting/meeting and working with inbound customers, and the employees in the back are neutral which is the only positive side to it, as such I've allocated two stars. This place could improve only if, they improve on their customer service and up the speed of service. There's no reason an operation with such known brand has this many negative reviews/experiences, nothing is positive for this location. Fix it! RECOMMENDATIONS: Appointment appointment, appointment if you're able to deal with attitude. read more

Not a fan of this location. These phlebotomist need more training. I had to bite my tongue watching them butcher my kids arm. This guy just stuck the needle in his arm without finding a vein, and he wondered why no blood was coming through. He kept pulling and twisting the needle in and out of my sons arm. If you couldn't find the vein why would you still do it. He didn't even bother to check his other arm to see if that would work better. And the bathrooms were filthy, with no toilet paper. Not going to this location again. read more

I've been to this location twice to get my blood drawn. Checking in was easy and the lady at the front was helpful and polite. Right now during Covid it seemed clean and sanitized inside the lobby and where they drawn blood. I've always been terrified of getting my blood drawn. Tess was the one who drew my blood both times Ive been there and she is very comforting and talked to me to keep me distracted the whole time. Tess did great and I hardly felt anything. read more

Facility was clean. Apparently they fixed thier appointment issue. As a walk in i waited well over and hour and watched countless others arrive later and be seen sooner. So i assume all the complaints about not needing an appointment are invalid. There were no names on walk ins when i came in. About 3 names on appointment. But countless people were seen before me that arrived later. So on this date, appointments win. So make an appointment. I don't know what to say. Everyone said it didn't matter if I had an appointment but with no names ahead of me I saw quite a few people arrive after me that were seen before me. Sure it took a long time, but after being called it was easy and painless. I expected a long wait - these things are usually lengthy. read more

THEY DONT ANSWER THE PHONES!!!! I dropped something off today and they replied with "what do I do with this? Where's the the sheet of paper your doctor gave you with the tests" but the last time I had went for a blood sample I had given them the sheet with the labs and tests needed to be done and was never handed it back and now they don't answer the phone to resolve the solution! read more

I wish I could give 0 stars because honestly this place wasn't as great as I thought. When I arrived a man greeted me at the door and was very kind but the receptionist was yelling across the room saying my sister and I were not allowed inside because we didn't have an appointment. The man had proceeded to give us numbers and let us in because there was literally NOBODY IN THE WAITING ROOM!! But then the lady kept saying if we ever go back we have to make an appointment or we can't go inside. Her name is Jackie but she would give me a lot of attitude when asking me for paperwork. And I would hear the phone ring a few times and she wouldn't answer it, she would just ignore it. They should retrain receptionists into being more kind because I did not like her attitude not the way she treated my sister and I. read more

The heavy white lady at the front desk needs to check her attitude. It's not fun having your blood drawn so you should at least have some compassion for patients and not roll your eyes, the attitude is not necessary. She was very condescending, another patient checking in asked where to put their name and she pointed to a tablet and said 'uh where it says name' and rolled her eyes. Maybe she was having a bad day or maybe she hates her job but don't take it out on others, especially not on sick people. read more

I walk in and the woman at the front desk has a bad attitude and her face is unfortunately not any better she doesn't acknowledge you when she sees you waiting for her to call you over she finishes what shes doing and finally looks up and ask what do I need I tell her i need lab work and she just point to the kiosk doesn't offer to help or even ask if it was my first time nothing I have yet to go in to get my blood drawn but if their attitude is anywhere near hers i will take my business elsewhere I dont need a snotty receptionist ruining my day. Thanks to customers as myself she has a job! And she should be at least a little kinder to us, the lady before me was not to happy when she walked away either I dont see a name tag on her but she is thin brunette with highlights. read more

This place is terrible, something always goes wrong. The ladies on the front who conveniently have their name tags facing the wrong way were no help. First time I came they lost my insurance Information that I didn't carry on me so another day then... This time I needed to have a glucose tolerance test done and you have a child in kindergarten they'll basically tell me that I'm SOL there's nothing they can do they can't see me after lunch either. They couldn't even help me figure out another location that might accommodate me. If you NEED to go here make an appointment otherwise your invisible to them read more

Rude staff in an unorganized dirty little facility. Masks slung around chins don't cut it. Neither does sneezing into your hands and then continuing on with your paperwork without properly washing. And I come here for my health? read more

It was super packed and I was and out in less than 30 minutes! The staff was friendly and helpful! Very professional!! Thank you Jackie for being so good at what you do!! Definitely 2 thumbs up!!! read more

I love this place I was in and out in 10 minutes Elaina drew my blood and she was wonderful the place is clean and the staff was very polite

I had absolutely no issues here. I was in and out in less than 15 min. My lab draw request was done prior to me coming, everything reached Quest electronically and they were efficient and very polite. I read the reviews and do not know if I was here on a good day or not, but i definitely was not treated rudely or saw anything inappropriate. read more

Let me start off that this place doesn't even deserve 1 star!!! Yes, I will highly agree with everyone's reviews about customer service!! I hope with this review they will do a change or I will just take it to corporate. This review is due to observation and how they treated my mother. First off I get it that they are trying to catch up with technology and putting kiosk to check in but here is where they lack on their customer service. First of all we all know that 80 percent of the patients that go are Middle age, elderly and hispanic that have some or no experience on how to use a computer and most don't own one at home and I have seen kiosk are being used in doctor's office, labs, dmv, and at fast foods but as I observe the times that I have taken my mother that I walk in go straight to kiosk put the info what they are asking and it checks you in and you see your name on the tv screen with all the others that are there waiting to be called. I observe two middle age couple up at the kiosk (tablet) trying to put there info into the computer (kiosk) and they look so confused they would look at the girls that were behind the counter to see if at least one would help but nope not one didn't even bother they just went on doing whatever they were doing and this couple was standing there with frustration in their faces. I don't even recall if the couple said a word to the girls in the front because they were at the computer doing something some were running from the back to get papers or calling other patients but that couple stood there for quite sometime probably trying there best to fill the info that was required. I mean c'mon quest lab employees if you see somebody having trouble with the kiosk at least have the courtesy and help those that can't. You know that the majority of your patients have no clue on how to use the kiosk even if they have been there multiple times they are still going to have problems have a heart and help those in need!! Now here is where my mother comes into the picture she went to get her labs done the other day and this time I did not go with her and she is one that knows some what how to check in but still struggles to put the correct info so of course she filled all the info the best she could and sat down and waited for her turn now mind you she went in at around 11 something before the techs went to there lunch break I guess at 12 and there wasn't that many patients waiting so she notice that people were being called in and she wasn't so she patiently waited to see if they would call her and some techs were getting ready to leave to lunch and still nothing I mean I'm sure these girls behind the counter knew that they had a person in the waiting area which was my mother and she was the only one there and you would think that they would say something to her but nope they just continue doing what they were doing before going to lunch so my mother said to herself what's going on why are they not calling me in seems that they are about to close for lunch and don't care if I'm here so she went up to the counter told them she was waiting and whatever employee that said to her did you check in at the kiosk and my mother said yes and she took a look and said to her oh you put something incorrect so my mother corrected and that's when they took her in. But you mean to tell me that because my mother typed in something incorrect your not going to check to see why she is sitting there while your about to close to go to lunch!! Damn does this place even give a s**t about people I know that QUEST DIAGNOSTICS Owner/President of the company must care on who they hire to represent their company because some of the employees at this facility need to be examined and retrained them on their customer service skills!! Do your job correct people because if it wasn't for these patients coming in you would not have a job!!! read more

I have dealt with quest diagnostics before, but apparently this time they have failed me. The only reason for me to write this review is to inform others that they may be trying to pull a scam. I recently had a procedure a few months ago with my doctor who used Quest Diagnostics as their lab. My medical insurance has a contract with QD. Which means that QD charges for a procedure done at a flat rate amount. But the contract between the two parties shows an amount for that procedure at a different amount and they cannot bill for the remaining balance. For example, today I get a bill from Quest Diagnostics telling me that I owe a balance. I call their 800# on the invoice and the customer service rep is trying to tell me that the amount owed is this is my copay for my secondary Ins. When I tell her that I don't have two insurances I only have one. I also explained I don't have to pay anything for this procedure. She begins to look up my info and tells me she didn't show any of my medical Ins info. However, she does see that my insurance did pay a portion (which is the contract amount) and it's my responsibility to pay the remaining difference. I told her again that I should not have pay anything. Now instead of her doing her job and calling my insurance to verify information, she tella me that I have to call my insurance myself and figure out why. When I called my insurance company, they notified me that there is a contract between them. The insurance representative also informed me that it is against the law (in CA, not sure if it's period or just my state) for QD to bill me for the remaining balance, because of their contact. So, instead of QD CSR actually doing her job, I had to do her job for her so I don't get billed and more and cleared up this matter without be not getting paid for all time I did. I cannot begin to express how frustrating it is when people do not do their jobs efficiently and correctly. When you are getting paid to do a job you should be able to do your job effectively without at the expense of somebody else's wallet and time. Hopefully, this is the last time QD pulls a fast one like this! read more

My mom and daughter both went in to Quest Diagnostics for a unique lab work on Sierra Lake Parkway. The receptionist fail to tell us there should be no eating or drinking an hour prior of the lab test. After we found out the tests on both patients were done incorrectly, I connected Patty Sanchez via several text, phone calls and left messages. Ms. Sanchez failed to return any communication with me. Based on not returning my calls and text, I went to the lab in person and the receptionist called Patty Sanchez and immediately Ms Sanchez picked up the phone. I gave her the name of the lab work and explain both patients ate and drank before taking the lab work. Ms. Sanchez basically stated it was not her problem and I needed to contact the doctor and the insurance company. The behavior of Ms. Sanchez should alarm any patients who goes to the lab. I am planning on report her to the state because medical issues should be taken seriously and in a timely manner. read more

Quest Diagnostics - Laboratory Testing Near Me - Fontana, California

Waited almost 2 hours to get called in and there wasn't even a lot of people there. The phlebotomist jammed the needle in and kept moving it and twisting it around. it was hurting the whole time. He was clearly nervous because he was sweating so much and it was freezing cold in there. He took out so much blood from one arm and decided to jam my other arm because my "blood was coming out too slow". I started feeling really lightheaded and dizzy because it was so much blood taken out already and thankfully he stopped. He just walked out the room for 10 min, came back and said they might have to call me to come back and get MORE blood work done. I went exactly a week ago and I'm glad I haven't gotten a call!! Now I have this nasty ass bruise on my arm..Never going back AGAIN read more

Quest Diagnostics - Laboratory Testing Near Me - Fontana, California

Yet another problem with quest. Surprise surprise. This time Elena has no idea what she is doing. She could not draw blood,wasted our time, and was so lazy! Also no one would help with a handicap patient. This place has the worst customer service and they can't do the one job of drawing blood. Ridiculous! read more

I never do reviews but this location is by far the worst place I've ever been too. They clearly hate their job and are extremely rude. You can't ask a question without getting a rude response. Long waits and there isn't even a lot of people. Never going back again. read more

If you like being treated like cattle this is the place for you. First time I went I embarrassed the nurse by reminding her she forgot to put her gloves on she didn't like that and argued with me why she does not have to put gloves on while applying alcohol to my arm. Second time I went during the Covid I took a dozen pictures of nurses not wearing mask. Third time I went line was very long no big deal got in it and waited like everyone else. After about 30 minutes A quest employee came out yelling at us because we were blocking the sidewalk. Then she went and told us all to wait in our cars and she would let us know when we can get back in line. No "thank you" no "sorry" no "please" just absolute rudeness. I went home read more

They were fast and made it very easy, lady in front was very nice , I wish all recipients were all like her keep up the good work

Seriously one of the worst quests I have ever been too. The front desk girl was horrible. She was rude. She would call me up and just have me stand there. I thought I was going crazy like "did she just call my name or am I hearing things??". Then she would just speak in such a rude tone like everyone around her was stupid. Every employee there just seemed to want to leave and hated people. 2 stars instead of one only because the person who drew my blood, thought also not personable did it in only one poke. Try the quest on Lemon in Rancho instead. read more

No appointment. Walked in and out within 15 minutes after I checked in. Very clean and organized facility. Veronica drew my blood without any issue and very friendly & professional. read more
