    I wish to give them zero star, this location of lab quest ( Tustin) so bad, Messy, no respect for the other's appointments time .They will make you wait forever even if you have appointment with them and checked in, more than one hour delay I was waiting and they called another people they came after me!!!!

    Micheal was really nice~ I just did my test today~recommend this location. I worried a lot before I came bucause seeing a lot bad reviews at yelp. But not bad, I had a good experience here today.

    Nice waiting area, no receptionist.  Check in at the kiosk.

    Lots of low reviews here and I understand that, but this is still my go-to for tests. Don't come here without an appointment, make sure your doc sent the lab order to Quest, bring you ID and insurance card, and everything will be ok. I agree things would be better if there's someone available for checking in and for answering questions, but in most cases it works. If you create an account online, you can make reservations, get reminders, and usually see results before your doc contacts you. I especially like the graphs of your blood test results to see your trends over time.

    Bruised arm

    Made an appointment but while doing the self check in, which I find very impersonal, only one kiosk was barely functioning. This is what my arm looked like a few hours after the tech dug around for awhile trying to locate the vein.

    No personnel up front, only self check in. Saw a handful of folks have difficulty with this process

Online appointment on their website was easy. Pretty efficient process as they sent text reminders with the address and also a reminder to check in by clicking on the link from the text. Once I was in the waiting area, a male staff member came out to let everyone know to pay attention to the screen to make sure our names show up and how many people are on the wait list. He explained that the ones who made appointments are given priority. He also asked for everyone's patience as there were 23 people waiting with 5 phlebotomists. I really appreciate that he set the right expectations. I was assigned to Kim and she was amazing! Really nice, friendly, helped make me feel at ease and best of all, it didn't hurt when she poked my skin with the needle. Thank you!!! I was in and out of there in 20 mins.

Got here not only is there tons of parking and it's free. They got me in within five minutes of my appointment time. Rodrigo was my phlebotomist and he did the best blood draw I've ever had done. He also caught on my next labs that the test I'm having done needs to be done 7-9am, that was great because I already booked my appointment for 10 and had time to change it. Great catch on his part! Highly recommend this lab.

    I had a time sensitive order that needed to be finished and I would not have made it back in time…read moretowards my usual location. They close at 3:30pm on a friday and it was 3:05pm. Bring in Yelp to the rescue! Asked Siri , "find me the closest location Stat" and onward it brought me to this location in Orange. Parking was a breeze, i was greeted by Edith who assisted me with several of my orders. One of which i had to email. Word to the wise, wifi here is a bit tricky. So, i signed onto their "guest" portal via wifi and after several attempts was able to successfully send the order to them. Thank you Edith! I got lucky. It must be noted: Morning draws have to be by appointment: 7:30am-12pm. After lunch, walk-ins are possible. I made it by 3:15pm within walk-in hours and was able to be helped . Key note: this location is located on bottom floor, as you walk inside the building it's straight after security. They are open until 5pm M-F. I had to use the Kiosk to check-in via ID and verify insurance per usual and the rest was sitting in the waiting room. The vibe here is lovely. Its a small waiting room, with limited seating ( i counted 6 chairs) but it has a tv for one to watch while they wait. Edith, Brianna and Sherri at the front desk were friendly, welcoming and super helpful with my email/order issue. Each Labcorp location has its own vibe. This one is cozy yet uplifting. Once inside the Phlebotomist named: Louis Helped me. My arm wasn't being helpful, and mid-way we had to abort mission. I had a small, tiny issue with vasal -vagal nothing some rubbing ETOH can't handle. Luckily, I was able to get some samples needed for an immediate issue. Will come back for the remaining when ive rested for round 2.

I'm also still working at home so not going to my other usual spot in Newport Beach next to my office. Both times I've been in and out quickly but did have an appointment for each. What I really like about this location is the staff, they are super friendly and professional. Today I had a newer person drawing my blood while the other did the paperwork etc. while also helping the new person out. Both had great personalities and chatted with me the whole time. I'm not afraid of needles and get tests a few times a year but for someone who is nervous the demeanor of the phlebotomists here would help calm them for sure. I wish I wrote down their names because they both deserve kudos for being genuinely kind individuals. Even when I go back to my office soon I'll be coming to this location for my blood labs.

I wait for about 2 hours from check in as a walk in since the nearest appointment wasn't for a week out and this is a required drug screen for my employer. After my wait I get called up and told "we've done too many tests today so you'll have to come back on Monday". Keep in mind this was at around 2pm I was turned away but they state that they accept walking until 3pm. Absolutely ridiculous and who would have know that the lab can't run many lab tests or hit a "quota" for the day. As I was waiting, in case someone doesn't show up, I saw another gentleman be turned away for the 2nd day in a row due to the same "quota" being met. Highly do not recommend it's an absolute mess and waste of time.

Thereafter desk personnel reviewed my paperwork and noted my doctor had failed to assign billing codes. They could still proceed but I would likely get a bill despite having insurance.

Last year, I had the absolute pleasure of being helped by Breanne, and she was so kind, patient, and truly had the perfect hand. She made the process quick, gentle, and even managed to make me laugh, which I never thought would happen in a lab chair. When I had to come back for my annual labs on 9/26/25, I honestly just hoped and prayed I'd see her again. To my luck, she was there! Breanne has such a calming energy and knows exactly how to put patients at ease. She turns something I usually dread into something I can actually walk away from feeling cared for. Thank you, Breanne, for your kindness and for making such a difference in my experience!
