    I'm giving this Quest Diagnostics location on San Bernardino Rd in Covina five stars. I've been here more than ten times at this point, and honestly my experiences have consistently been smooth and efficient despite what some of the other reviews say. I think timing really matters here. I never come in for fasting labs and I almost always book afternoon appointments, which I suspect avoids the morning rush. Most of the time I'm able to get a next day appointment, and today I even got a same day slot, so it's hard for me to complain when the scheduling has been that convenient. The phlebotomist experience can be a bit hit or miss. Sometimes they're chatty and friendly, other times it feels very quiet and strictly by the book. That doesn't bother me though. I'm not there to make friends, and as a healthcare worker myself I get that they see a high volume of people and need to keep things moving. They're always clear and thorough with instructions, which I actually appreciate, especially since I'm not the biggest fan of blood draws on myself. Sometimes it hurts, sometimes it doesn't, but overall the process is quick and professional. The online check in system is a huge plus. It can feel a little tedious since they ask for a lot of information, and I'll probably just make an account to make it easier next time, but once you get the text and check in on your phone, you don't even need to use the kiosk. Even when my name didn't show up on the waiting screen, I was still the next person called. This location is super convenient to my home, the care feels standard and solid, and even when I've had to cancel appointments it's never been a big issue. For me, this place does exactly what it needs to do, and it does it well.

    You can barely see where GABBY took my blood

    The phlebotomist named Gabby at quest diagnostic is the only person that took my blood, and I didn't even know she had taken my blood. She's so good! I was hospitalized in December at community Hospital, and everybody that took my blood there didn't know how to find a vein, and I still have bruises from the damage they did. Gabby at quest diagnostic found my vein, drew my blood, and I had to ask her when is she gonna draw my blood and she tells me that she already drew it. I think they should make Gabby supervisor and training every other phlebotomist across the globe how to do it and do it right. On another note, she never tried lingua tacos. lol. Gabby if you're reading this, I want thank you for treating me with respect and I think you're an awesome person. This is coming from a Veterans from the United States military. Heck, I'm voting for Gabby for President!!!

    Sad and pathetic lobby.

    I hate Quest now. Expecting customer service? Forget it. They've now turned all the offices into prison like rooms with grey walls and kiosks to check in. There's no way to get help if you need it unless you can catch an employee when they come out to call someone for their turn. Recently I booked both myself and my son for appointments at the same date/time. I checked in online and didn't realize it only checked in myself. I asked the staff member when she called me to make sure my son was next and she said she would check after she finished with me. Once she did, she said he wasn't checked in and I had to go back outside to the kiosk to check him in. By the time this happened, it said his appointment time has passed and it cancelled his appointment and he would have to wait as a walk in (30-60 min wait). I ended up having to make another appointment for him for another day. We arrived on time but still had to wait 25 min for him to be seen. Unfortunately I am at the mercy of this clinic as they have the monopoly for bloodwork services that is covered by my insurance. One star for the nice lady who helped us. She was quick and efficient.

    The workers here have thee WORST attitude! Not welcoming at all. Their approach to patients when they ask questions is very unprofessional and unwelcoming. If I didn't have to have blood results by Tuesday I would have walked up and gone somewhere else. They need better staff.

    I know many places are given a few stars. But the reason for 5 is because l made an appt; got in and out literally within 10 min of checking in. Although they are short staffed, l was still able to do my lab work in a jiffy.

    Don't miss this hidden sign!

    Lab corp discriminates against minorities and the treatment that is give at the Covina location is…read morenot acceptable. I have spoken to the District Manager Christina couple of times. She has communicated that there is not a bigger location to accommodate this community. They closed the location in West Covina and opened one in Baldwin park. I have to drive my parents further and further from their home because you cannot secure a location that serves the area that they reside in. That is an excuse. There is no posible way you are going to tell me that there is no other location. You have your clients wait upstairs then they are brought downstairs to the basement to wait again. In the basement there is a maximum occupancy of 29 people but the tiny lobby is full at 14 seats. There is no ventilation. You are in extreme close proximity to others. At the very least put an air purifier. The employees at this location are always moody. They look as upset and dissatisfied as the clients they serve. They communicate with the tech upstairs via a walkie talkie that is getting paid as a door monitor. So you charge the insurance of these customers the same as any other city and you give the ridiculous excuse that you can't find another location. That is a flat out lie. You do it because not enough people complain. Because as minorities we are complacent and we traditionally have accepted less. You know this and take advantage of it. Our time is irrelevant to you. You keep maximizing on the amount of money you make per location and we just keep waiting. No regard for our time or the conditions in which we wait. Every time I come here we wait over an hour and a half. YOU HAVE THE CLIENTS TO SUPPORT A BIGGER LOCATION. Please give this community the respect they deserve. Stop ignoring the very apparent need and dismissing it. I am tiered of seeing how you treat people depending on location and demographics. You should be ashamed of this very clear fact. Stop ignoring it! This community deserves better.

I had to lift my arm out of my one sleeve so he could draw my blood. Then he gave me the instructions for the 2 stool samples. One had to be refrigerated. I took the 2 tests back the next day. He asked if I had the paperwork. He had already made a copy of the order, so I thought that was odd. I ran back home and picked up the paperwork. The facility closed at 2:00, so when I walked back into the facility, it was 2:00. I made the comment that I was glad that I made it on time. The phlebotomist said, "Well, you showed me one of your breasts, so I waited for you. I was so shocked that I didn't know what to say. I had an appointment with a gastrointestinal doctor the following week. He looked up the results of the 2 stool samples. He stated they weren't there. I went back to Labcorp, and the lady at the front desk had no idea. She told me to call the corporate office. That was a joke. I called, and the customer service rep had no idea where they were. She actually told me to come back in and redo the tests. I told her that the tests had to be done at home. Really?? I made 4 phone calls to Labcorp and finally spoke to an actual person. I asked to speak to a supervisor. He left me on hold for a long time, then finally took the information. A supervisor did call me back, and I explained the problems. He told me that it was probably lost. How would it get lost since I gave it to the phlebotomist? The supervisor told me that he would call me back. He never did. Is this the way for a facility yo operate? I would never go back there. The phlebotomist was unprofessional, and they lost 2 of my tests. Those tests were very important.

When we arrived, a Hispanic female employee was sitting in the corner near the front counter, using her phone instead of assisting patients. I said "hello?" before she finally came over to help us. We needed to complete a stool test today. She asked whether we wanted to take the test home or complete it there. We told her we were ready to do it today. She then gave us a urine cup with the lab order inside the specimen bag. I asked where the stick was to transfer the stool into the container. She told me they didn't have any sticks and suggested that we use our hands. I was shocked. She then gave us a pair of gloves instead. I told her there was no way a large laboratory company like Sun Lab should be out of such basic specimen-collection supplies. She eventually went to the back and came out with two sticks, saying, "I found these for you." After my boyfriend went to the restroom to complete the stool test, she went right back to sitting in the corner using her phone until the location closed at 12 PM. I am raising this concern with the manager because this was extremely unprofessional and unacceptable. If management sees this review, I strongly encourage you to review the security camera footage from today, August 8, 2026, around 11:15 AM to verify what happened. There were also two other Asian employees working at the location. They were standing and actively working, while this Hispanic employee was sitting in the air conditioning and using her phone. I hope management takes this feedback seriously and addresses the issue appropriately.
