Not sure why all these reviews say that the staff is friendly. They're only friendly amongst themselves when they're laughing and talking about their plans for the day or a vacation they plan on going to. Very unprofessional. They have us waiting in the small lobby in the basement with horrible Wi-Fi, just like someone else mentioned in these reviews, because it's true. And not only do they have you waiting in the lobby but once you get seated, you're sitting there for like 10 minutes waiting for someone to get your blood drawn personally it shouldn't have to take that long. Long story short in the past it used to be smooth sailing but now it's just a total shit show. Don't come here and support them, please go somewhere else.

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.

The one near my work doesn't have availability until several weeks out, but this one had a ton of availability. It's a little run down and not in the nicest plaza but I think because it's kind of hidden upstairs, it's fairly quiet here which is excellent. They had the same check in process as other Labcorps that require you to use their computer check in system. Overall, everything was the same but it's just so quiet here that I'm giving it 5 starts.

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.

Today, I went with my boyfriend to this Sun Lab location because it was close to our house, and…read moreunfortunately, we had a very disappointing experience. 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.

My throat was swelling, I could barely speak, and it was becoming difficult to breathe normally. I didn't catch the name of the woman at the front desk who checked me in and gave me my injection, and I'm sorry for that. She stayed calm, explained everything clearly, and treated me with genuine kindness when I was scared. Dr. Amrit Dillon came in quickly, took my condition seriously, and after the injection he came back more than once to check my swelling and make sure I was improving. That extra attention really gave me peace of mind. Everyone I interacted with was kind and professional. What may have been routine care for them meant a great deal to me as a patient experiencing these symptoms for the first time. Thank you all for taking such good care of me.
