Super slow. No one is working the desk. Only two people working and they are incredibly slow and unfriendly. Never coming here again.

MAKE SURE YOU HAVE AN APPOINTMENT! Even if no one is ahead of you and they are open they will not see you. Not worth the drive over!!!

Phlebotomist did a poor job drawing my blood. They left the injection site very bruised, bloody, and painful.

The logistics of visiting this place is terrible. I would give it a zero star if I could. There's…read moreno free parking. You are forced to park in a parking lot which charges $4 after 30 minutes and KEEPS GOING UP the longer you are there. There's no parking validation. When I was there a lady tried to pay with her iPhone and it didn't work. She then tried with credit card and that also didn't work. It held up the whole exit queue. It doesn't take cash and there's no human attendant. This is not the fault of Labcorp. They don't own the building they are just a tenant here. For the actual service inside Labcorp it's good. But you're constantly checking the clock to make sure you are not over 30 minutes due to parking. Which is very stressful for an already stressful situation. This is the only Labcorp location I've ever been to that charges for parking. Just go to the location in Fountain Valley. There are TWO locations with FREE parking within the same hospital (Memorial Care). P.S. If you ask ChatGPT or Gemini for parking tips they might tell you to park across the street or on the street. This is not viable. Across the street there is a medical plaza but they enforce parking very strictly. If you try to park there you are likely to get towed. Also street parking is impossible there's very few spaces. Just go to Memorial Care.

I rushed here after work and arrive 20 minutes before closing time there was no one in the front for over 10 minutes. And once somebody came out to the front, they turned me away and told me that they wouldn't take me without an appointment. Every other LabCorp, I've ever been to take you without appointments. I asked if she could just take me since I was already there and had been waiting and she just turned around and ignored me and started helping a different patient. Aside from them, not answering their phone from an hour not having anyone to assist you at the front desk over 10 minutes. They are rude and unprofessional. If they don't take appointments, they should say that on their website somewhere or answer their phones and say that! Absolute horrible customer service.

Note: They are appointment only as of September 25th of this year! (The sign on the door says this…read morepolicy is temporary) But because of that they're appt only, this office is super organized and you don't have to wait super long for your appointment. I waited about 5 minutes to be seen which was outstanding! While I was waiting I saw a technician come out and help an elderly man who only spoke Spanish, no English, check in (all on her own accord to be nice) which was very kind of her! Overall, everyone at this location is super caring, and it's very efficient! I even got my lab results back the very next day even though it's Saturday! Super impressed! Highly recommend!!!

Review for Thomas Bowers - OC Home Blood Draw…read more As someone who works in the medical space, I have a sharp eye for sterile technique, professionalism, and quality care--and Thomas Bowers absolutely exceeded every expectation. From start to finish, his process was flawless. Thomas arrived exactly on time, followed every procedural step with precision, and executed the blood draw so smoothly I didn't even feel the needle go in. That level of skill alone deserves praise. But what truly stood out was his attention to detail, calm demeanor, and the respect he showed for both the clinical process and my home environment. After the draw, he personally delivered my samples to Quest and followed up via text to ensure everything was handled. And just when I thought the experience couldn't be more impressive, I received a beautiful thank you card featuring a photo of elephants--an unexpected, thoughtful touch that now sits proudly in my home. Thomas is a class act. This is concierge-level care with clinical-grade precision. I've already referred him to several friends and can confidently say he'll be my go-to for all future blood draws.

I have a severe blood injury and injection phobia. I pass out even at the thought of giving blood…read moreor getting an IV. I found Thomas on Yelp. His communication was great, his price was fair and the blood draw was quick and easy. Thomas was friendly and easy to talk to. He texted me when he dropped my sample off at the lab. I could not have asked for a better experience.
