I was fifth in line for those without an appt. The indoor seating area was very clean and nice and had a screen to show the list of those with appts, those without appts, and how many were being seen at the moment. As for the blood work appt I had, the lady was super nice. Everything seemed professional and clean and I was out of there really quickly! Parking was really easy. Lots of spots. I believe there are two entrances but regardless the signs to Quest are helpful. Overall, would like to go to this location again, though I hope I can get an appointment ahead of time!

The people who work there are never very friendly, and they talk to people like they're stupid. When I have been in the waiting room waiting for mother, I hear the way they speak to people, and it's unprofessional. Today, I had to drop off a sample for my mother, and the woman at the front desk seemed very put off that she didn't come herself, I was given an attitude about it. When I was dropping off the sample in the back, one of the phlebotomists screeched at me: YOU HAVE TO CHECK THAT IN!! YOU CANNOT JUST LEAVE IT!! I was not sure if she was talking to me, so I turned around and she screeched at me again. I sort of laughed and said: yes, I know. That is why I am waiting here for the tech to take the specimen from me. As I walked out, I said: I think you all need to stop drinking coffee because you're wound up way too tight. I just hope I can get my mother's doctor to send her to Quest next time because they are friendly there. Never had an issue.

The place is small especially the waiting room is packed with people cramped inside not to mention, standing room only. It's outdated, unclean & unsanitary. Front desk staff looked miserable and unfriendly. Waited patiently outside the facility in the hope of getting called soon for my 7:15am appt. Got called in within 20 mins. While waiting outside with 7 other people also waiting, you can't even hear your name called out since there is no intercom or loudspeaker available. Phlebotomist was nice, the only thing positive and with effort around here. Please consider MOVING to a bigger, newer location to accommodate patients' needs efficiently. A Labcorp in Chino Hills sounds nice.

My wife came in today for scheduled bloodwork for my son. He had an appointment for 3:30 PM, and…read moreupon arrival, they checked in and were put in queue as it showed on the screen in the lobby. Given a Friday afternoon, it was crowded, but saw my son's name on the list confirmed they would be seen in order. As they waited, a lady came in and got the attention from the staff, and asked for a walk in, claiming she had an appointment. She didn't but they somehow gave her a spot. As my wife waited, seemingly longer, they noticed that my son's name was no longer on the monitor queue. Other customers were being called in, including some that arrived after them. My wife finally got a staff member's attention and told her the situation. The "rude" female insisted that they had no control over what the screen showed. (Odd that you can literally put people on the walk in queue but have no say with actual scheduled customers, BS). Long story short, they ended having to wait until all customers were seen, including walk appointments. After, pleading with the staff member that we were scheduled, they did nothing to help and made us wait until closing. Again, scheduled appointments are confirmed via text and email if you have been here. But no attempt to fix the situation. The worst experience ever at Quest (given we've been here several times and haven't had an issue). The horrible, staff member who would not help, and to top it off, she kept telling customers how busy they were because they were short staffed. That is no excuse when assisting customers. Second, saying that they had no control over the queue when they were clearly able to take walk ins, but mysteriously removed my son from the list. We've been to this location before, but it seems that horrible employees lower the standard of customer service and the overall business. Even worse is that so many people rely on Quest because many private doctor's offices do not handle internal bloodwork; so Quest has this massive contract with nationwide offices to do bloodwork for them. The customers who rely on Quest are our family members, whether sick, elderly, some dealing with major medical issues, yet they might come here and have to deal with the BS that my family dealt with today. Just horrible. Hoping to figure out if there is actual management or staff supervision to bring this issue to.

I tried calling right in front of them The Doctor Who referred me and they insisted I step outside. Very frustrating.

I ended up calling the corporate office and file a complaint which I doubt they would do anything but I'm doing what I could so that others don't have to experience the same thing that my family had to go through.

They were unable to successfully draw blood from my mother after two initial attempts. The third attempt was finally successful but after 1.5 vials, the tech stated that they needed to try the other hand again to see if it would be faster. 2 more unsuccessful attempts on the other hand and they ask my mom if she'd like to come back tomorrow, when their coworker is working instead (mind you this is after already telling her to fast for today's blood drawing). She ended up leaving and going to a different lab. Absolutely amazed that this place is still open. Someone needs to look into it.

My 93-year-old mother arrived 10 minutes early this morning for her 8:15 AM appointment. Early. With timestamped proof. But the front desk staff confidently, and incorrectly, declared she was "extremely late." Bold move, considering their computers apparently exist purely for decoration. When we tried to show them the evidence, they gave the universal "I don't get paid enough for this" eye roll and refused to even look. Facts? Evidence? Reality? Absolutely not. Not on their watch. Then, because nothing says "we messed up" like doubling down on arrogance, they made her wait 1 hour and 15 minutes as punishment for their mistake. A 93-year-old. Sitting. Waiting. Because staff couldn't be bothered to admit they were wrong. If you enjoy chaos, incorrect accusations, and customer service so bad it could be used in training videos labeled "Never Do This," this is your place. If not, consider literally any other LabCorp, or honestly, a dartboard and a home blood draw kit might be more accurate.

I did not experience any rude ladies there at the front desk. In fact, the gentleman at the front desk helped me with an issue and was actually nice to all others who went to ask for assistance. He was even pretty patient with non-English speaking people. The nurses do cycle to the front desk, but they go only to call the next person. What I did see were a few people (about 3-4 in the 45 mins that I was in the waiting room) coming in right at their appointment times expecting to be served immediately, without checking in. It's not accurate if you don't know the process. Let's be real, an appointment gets a planned time, but if they are early/late a bit, that's expected as these offices get LOTS of people who need lab work. A walk-in without an appointment at 10:15 had an estimated service time of 2:30 pm. Better to make an appointment. The nurse that took my blood was nice and professional! Visit this place for your lab work, just don't expect to be treated like you're at a 5-star resort and you'll be fine!

I witnessed patients being rude to each other, and patients being rude to the employees regarding the long wait times. It felt very uncomfortable to witness while sitting in the waiting room. Also, I waited for over two hours here, and then they turned me away because they said they are too full for today. Then, they told me to show up at 7 am tomorrow to get in line for them to open at 8 am. They did not apologize or seem sorry to say this to me. Management should make this place appointment-only if they cannot handle walk-ins. ALSO, if a Labcorp member is planning on leaving me a generic response to this Yelp review like: "Hi, We are sorry to hear that this was your experience at the Upland, CA Patient Service Center. Thank you for bringing this to our attention. We will look into this issue further." Just know that that is a USELESS comment for me and anyone else coming to your business. Why give me an extremely generic response to my message if you aren't going to fix this? Maybe actually fix the wait times by getting rid of walk-ins or having a much easier, well-functioning scheduling system. If it is fixed, then I will value your response.
