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 It's outdated, unclean & unsanitary.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.

These two without hesitation helped us in making this experience and appointment appreciative of their profession. All I can say is if you have rolling veins ask for these two because it was an experience with waiting for. Because being poked 2-3 times is no fun and they made it seamless. Thank you

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.
