    Hematoma
    Elizabeth T.

    I have a hematoma the size of an egg. I asked her to back up as I could tell she went thru my vein and she refused. It's so large I can't bend my r elbow. I'm R handed and 2 days before Christmas and all the cooking I have one usable arm. I get my blood drawn every 3 mos and I have NEVER had anything close to this happen. I tried calling them and getting a human is impossible.

    Terrible service. Unhelpful and brusque staff. Poor booking system that accepts walks ins and then allows staff to reject your appointment

    Make sure you make an appointment! If you don't, the wait time is long. Customer Service is always great.

    Made an appointment online for 11:45am, arrived at 11:30, checked in using the QR code sent to me…read moreand received a message I would be notified by text as to when I would be called. The waiting room was full and there was a line out the door. I waited about 30 minutes till an open seat was available to wait inside as it was starting to warm up. We were told they were behind an hour so there was definitely going to be a wait. Everyone was getting impatient, myself included. Many people rescheduled and left but I waited it out. It took about an hour and a half wait from my arrival to be seen. Once I got called back, everything was quick and easy. The technician who drew my blood was friendly, gentle and professional.

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 It's outdated, unclean & unsanitary.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.

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.

    The one word I have to describe this office is chaos. Too many people. Too small of an office…read morespace. Not enough chairs. Patrons watching videos with loud volume on their phones and others enjoying speakerphone or FaceTime calls in the waiting area. Is there a secondary waiting area? Yes. Did any of the staff let anyone know about that waiting area? No. Are there any large signs in the waiting area letting people know about that secondary waiting area? No. Was staff walking over to the secondary waiting area to see if anyone was there when they didn't respond to their name being called by the front office or the phlebotomist? No. So is there practical use to that secondary waiting area? No. Not at all. Automated check in which is nice if you are young and can manage technology, unfortunately most of the patrons are elderly and/or have some level of disability. Even though individuals can select their language when they check in this apparently is also confusing. The front office staff yell back and forth which is terrible in a small office space. When I have come to accompany my parents, I always end up helping others check in also. They first try to ask the staff for help but unfortunately are ignored then look around and ask me (or anyone) for help. Even then, staff simply just ignores their patrons. Really this is a horrible environment for a medical office. And the security officer Michael is completely unhelpful and unuseful. The best way to come for blood work is to have an appt. If you have an appt they try to keep on time. If you walk in, vaya con dios mi amigo. Even at 8:30am the walk in wait is projected to be 2 - 3 hours long. Now can you understand why the waiting area is jam packed with no place to sit or stand? The one time I actually came for myself was a mess. This ended up with both my arms used as pin cushions and the end result was using both hands (because they couldn't get the poke on either arm or one hand). This was after I informed them they would need to used a butterfly. I guess they don't believe me despite the fact that at my age I know my veins and I know what works for me. After all the failed pokes and having to sit there with warm compresses on both arms and hands and having to pull in a second phlebotomist they finally used a butterfly and got it. Too bad they didn't listen to me when I first got there but maybe they get some joy from poking and digging uselessly into people's arms and hands. Needless to say I hate this place. This location is the worst. I would have given them negative 5 stars if that was allowed. There are other labor locations and I would recommend trying them unless you have no choice. Or better yet, if your insurance allows, go to Quest.

I…read morehad a set appointment at 11, arrived around 10:15, checked in, and was served right around 11. 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!

    Everyone, patients and employees, are angry and rude. It is not a good place to be unless you want…read moreto lose faith in humanity. 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.
