Great front desk, friendly and knowledgeable. Phlebotomist was excellent, didn't even feel the needle . My go to spot for blood test . Parking garage was close, safe and easy to access. read more

Made an appointment for 915. I didn't get in until 1015. What a joke what's the point of an appointment. The worst part is people are sick and the waiting room is literally 40 chairs next to each other with no space in between. read more

9:15am appointment on 4/22/26. Arrived and checked in at 9:05am. They didn't call me back until 9:55am. Why bother offering appointments if you still have to wait 40 minutes? read more

Do not come to this location if you have a infant for lab. The nurse there do not have any experience to draw the blood from baby. The first nurse said they only allowed to do it on the foot which is not true. The other lab we went in the past has always draw from the arm. She tried the foot on the baby and did not collect one drop in the tub. The blood is all over her gloves. She was going to try another foot which I rejected. She called a senior for help and the senior does not confident about drawing on the arm either. She said she will only try. She had to pinch the needle inside of the skin and kept moving for several times to find the vessel. Thank goodness she finally found the vessel. Compare to the other location we went 3 times in the past, the nurse there could find the vessel on the first try. read more

ANYWHERE BUT HERE! This place is rigged. They purposely go behind so you have to pay the parking fee there. Not only that, regardless of your insurance, for some reason thy require a card on file? They went ahead and FULLY CHARGED a visit ordered from my doctor without even using my insurance! The only nice part was the lovely older gentleman who took my blood. Other than him, there is nothing good about this labcorp. I've been to 3 other local labcorps and experienced no issues like them. Whatever you do, DON'T GO HERE! read more

Wait, time is ridiculous! Standing room only. Total disregard for people's daily schedules. It's pretty obvious that what matters to them the most is raking in the most money at the expense of so many hard-working and so many sick people. In the photo you can't see all the people standing outside waiting. I was told to be here at 10 AM, my appointment was for 10:30 AM. I was not called in until 11:07 AM. After I'm called in, another 30 minute wait. UNBELIEVABLE! If the fire department was called in, I'm sure this place would be written up for having too many people in the waiting room. People are even standing behind the entry door having to catch it with their hand every time the door is open from the outside. Avoid this place! read more

Labcorp - Broken directory. Must go out and ask the valet where the office is - Laboratory Testing Near Me - Fullerton, California

This lab and their booking system sucks! I regret I didn't check their bad reviews before I booked my simple blood work appointment on their system. They overbook many patients so there is long waiting line in the room. Although I pre-scheduled my appointment 4 days prior, I was treated as a walk-in patience by mistake because they mixed up my fist name with my middle name. The front desk people are not effective nor efficient. They don't know how to handle their mistake and make it right with patients. Overall, this is a bad lab to go if you just need a simple blood work done. read more

Do not come here !!!!! Unorganized they mix up names had an appointment at 930 waited an hour until I asked they had me on the wait list !!! Ridiculous! ! Front desk have attitude ! They are mad at us for their errors ! read more

First off, the front only offers valet parking, which isn't ideal if you're just trying to get in and out for a quick lab visit. You're then directed to the parking structure, which is a total mess. It easily takes 5-10 minutes just to find a spot. What really stings? Labcorp doesn't validate parking. So not only is the process frustrating, but you're also paying for the privilege of that stress. read more

Someone in the front desk checked my mom in and it was more than 15 minutes before her scheduled time and they said if it's more than 15 mins it becomes a "walk in" and made her wait over an hour when she was there early, what a ridiculous policy. They should've told her that when they were helping her check in and informed her to check in later so she wouldn't have been a walk in. When I talked to the receptionist about it she was very rude! Parking was also $5 and $10 for valet. read more

Labcorp IT is unreliable. 2 out of 3 times I have been there their computer system is down. I had an appointment yet it took 1 hour for a blood draw. The office staff are trying their best to serve customers but they aren't getting the support they need from the company. Bring your printed lab orders because when their system goes down they can't access the digital lab orders. read more

Not sure why there is a need for an appointment when you have to wait forty five minutes for you to be called. Facility is clean and staff is nice but in my opinion it's very disorganized. Even after getting called into the room. I waited in my chair an extra ten minutes for no reason read more

I'm always getting lab work done and this facility was the worst I've ever been too. Overly crowded, the front desk didn't give me all the info and I had to run home to grab something and come back over an hour later. The lady at the front desk ( 4/3/26 ) was also a complete bitch and was rude. Worst experience ever, don't EVER come to LabCorp in Fullerton read more

Super quick and efficient. One of us had a 1245 appt and the other 115. They took us in early and we were able to leave before we even got charged for parking. Staff was professional, didn't even feel the poke. read more

I set up a time for my blood work and was in and out in -5-20 minutes The person that drew my blood was very nice didn't even feel the needle go in or out read more

Kindness is not what I experienced here. Rude, condescending and obnoxious front desk person.

What is with the bad reviews on this LabCorp!!! People are lying . This is my first time going there and I simply love it . I am a freek about needles, but thanks to "Ban" I am not anymore. She was so efficient that I didn't feel anything. The reception staff was amazingly friendly. The atmosphere was upbeat. Honestly, I don't understand why people are lying given bad reviews. From now on I will only go to this LabCorp. It's clean and very professional. read more

I got some blood work done a couple of weeks ago on a Thursday. I did not have an appointment. I checked online but there were no available appointments until a few weeks out. I arrived at 6:30 am and was out before 7:30. The staff was nice and the kiosk was user friendly. It took me a bit of time to find the place, as it's a bit hidden behind the dialysis center. There is plenty of parking. read more

I had schedule an appointment for 9:30 they didn't call me until 11:15 . So what's the appointment for? So frustrating! I was late to my other appointments. read more

Be prepared to pay for parking ($8... about, also valet in the front, self park in garage in the back) this place really needs to offer validation. LIKE SERIOUSLY, there's no validation. There are kind and efficient phlebotomists here that get your blood work done. Make sure your physician has submitted their order, so that when you check into the kiosk with your drivers license and insurance card, front desk will be able to clarify with you which doctor ordered what test. Also, always best to have a PHYSICAL copy of your Labwork order, sometimes the system has technical difficulties throughout allllllll labcorp locations. Always be prepared. DRINK YOUR WATERERRRR! fasting means NO EATING, WATER IS OKAY! Easier to draw on you. There are 6-7 drawing rooms and good amount of workers on shift to help things run well. read more

The absolute most inefficient people working the checkins at this location. We waited 45 mins to be checked in for an appointment and then told they are now closed when we asked why it was taking so long. Please work on checking people on time!! Learn something from Quest who can meet their patients on time and get them out in 5 mins. read more

This office is horrible. They are very rude and very curt. If you have options take them.

absolutely one of the worst local lapcorp locations. even with an appointment they don't take you in for another 45 minutes. small claustrophobic waiting room with every single seat full and packed in like sardines, absolutely will go to any other labcorp again before this one read more

I had blood drawn today and I'm not great with needles (I have been known to pass out). Bobby was very professional and attentive. It was practically painless...I mean it's still a needle. Thank you! read more

I had an appointment and still had to wait 45 minutes. Very unorganized at the front desk. The lab technician was terrific. The place was packed with no seats available. Making an appointment at any Labcorp is weeks out if you want an early morning appointment. Quest was so much easier. Also, no masks are available, and you have to pay for parking. read more

This place is horrible!!! My dad went 2 times and with appointment and they forgot about him. He was waiting for more than 1 hour. They are rude and have no compassion what so ever for patients . One of the front office ladies was on a personal call the whole time I was waiting. And they look and talk to you like if they are mad when patients ask them questions. They definitely don't follow providence values and not sure how providence would send patients there. read more

This is the best, cleanest, happiest Labcorp that I've ever visited. The staff is super friendly, compassionate, and helpful.

Bailey was super amazing she took my blood and was so kind and understanding I don't do well at all getting my blood done and I didn't even feel it and she talked me through it and helped it be the best experience I've had getting blood taken thank you Bailey Merry Christmas read more

Today I had worst lab experience in my life with Labcorp. There are more than 30 people in waiting room waiting for blood draw. In Quest Lab it took max 30 minutes to finish the work. But today, I waited 3 hours. A lady seat next to me also complained that she already waited 45 minutes after her appointment time. Finally they called my name, I need to wait another 30 minutes even seating on the chair to draw blood. The location on have two staffs on duty. And they are sloooooow. I was checked online to schedule an appointment, you need to wait three weeks to find an open slot. Such a terrible services, lazy staffs, and unprofessional experience. I hope all patients had the same experience voicing up. read more

I came here to get my labs done and I needed to hurry up and get in and out, and they were so helpful accommodating my needs. The staff was super friendly and made me feel welcome. I appreciate people like this. read more

Oh wow I had the most amazing experience on Friday, October 25 at LabCorp 100 Valencia Mesa It was a fantastic experience. It was very easy for me to locate and parking was very assessable. I did not have an appointment and they took me as a walk-in and it was not an issue and I barely waited 12 minutes. When I walked in I was greeted by the person at the front desk and she told me to go check in at the kiosks... The kiosks are super user user-friendly and I was delighted by that, that was super easy and nice because I am not techy at all and that usually causes me stress, but this was very user-friendly! Everything was clearly defined. I found the screen to show me my wait time and my name so I knew when I would be next ... Then they called me to the front desk to make sure they had all my information friendly very helpful. Then shortly I was called to the back by Bailey, who was so nice sweet kind explained everything to me and I was in and out in about 10 minutes. Bailey was very helpful and waited for me and walked me out to the front again. Because I got my tests done on Friday I assumed I wouldn't get results until Monday but oh my gosh I got all my results back on Saturday morning one day after all my blood was drawn! By 7:30 in the morning all my labs results were in!!! It was great visit and experience with LabCorp thank you everybody for helping me and being so kind and warm and special thanks to Bailey... 100% Thank You read more

This place is awful. Staff are rude, parking is bad, and this is across the way from the other Labcorp which is confusing. Parking is $8 and the building itself is so confusing without labeled places to go. It is also across the street from another LabCorp, which is confusing so if you arrive at the wrong one for your appointment, they won't see you and will make you wait the hour or so wait, which is going to cost you even more to park. It was my mistake going to the wrong one, but if I'd known that, I would've just stayed as a walk-in at the other one, and I would hope that they would give people a little bit of slack with something like that or at least be nice about it if they have to make you wait. You kind of feel like a cattle, it's really disorganized and people are jumping in line in front of you without the staff saying anything or acknowledging the wait time that it took just to get to the desk. read more

if I could give zero stars I would. don't bother checking in at the kiosk or your phone, they only care about people who walk up to the desk to check in. girls are incredibly rude. go to a different lab corp!! read more

Walk-in sign in at 820 am for a blood draw, 1050, still wasn't called for the blood draw. This place is so busy. I stayed when they said 1 hour wait for walk-ins, then I heard 2 hours, I gave up when I looked at my watch and it showed 1050. I was fasting. They did not care. I can't believe in saying this, but the DMV was better at least when updating who's next. The kiosk sign-in was useless. you might as well give it to the counter because you are going to give it again anyway. Plus, I stayed for almost 3 hours because I will pay for parking anyway. I don't know if it's the same across the board for all labcorp, but this is my experience on the one next to St Jude hospital read more

They could not cancel a test that's ordered from the doctor and now needs to be redone.

I asked the front desk repeatedly if they needed my paperwork. The front desk individual continued to tell me to sit down. I waited over a hour until the other gal told me she called me for my paperwork and I did not answer. :( read more

I've been to other labcorp locations and I had the best experience at this one! Everyone was quite friendly at this location. I was greeted right when I walked in. The check in process was simple and the wait for a walk in appointment for a weekday afternoon wasn't too long, about 20-30 minutes. Bobby was very attentive, making sure I was comfortable and explained the entire process, including different needle options. The only downside is the $5 parking :/ read more

The lady and gentleman at the front desk were so helpful and pleasant. I forgot my blood work paperwork and insurance card. They accepted copies from my phone. Miyana did a great job of drawing blood; easy and painless. read more

Everyone was so kind and patient! The older gentleman who drew my blood was so helpful and gentle! I will be coming here for my labs in the future. read more
