    Sorry, I had to use your photo, Michelle. She was also the same staff member who was very unprofessional with us today, so it seems like she may have been having a bad day. This staff member was rude and showed little patience while handling my toddler during a blood draw. Instead of being understanding, she blamed us and spoke harshly. She also grabbed my child's hand in a way that felt inappropriate, and then denied it. Healthcare staff should always be gentle, patient, and respectful--especially when caring for young children.

    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!!!!

    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.

    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.

    Check in was easy, the phlebotomist who drew the blood samples was very professional and competent. Overall, a good experience.

The last time I visited, I received a text message when it was my turn for my blood draw, so I asked if they could do the same today. The employee told me they couldn't because Saturdays are by appointment only and they don't accept walk-ins. My question is: if that's the policy, why was I allowed to check in and wait for an entire hour without anyone telling me? It would have been nice to know upfront instead of wasting my time. Better communication would have saved me a long, unnecessary wait.

Even with some computer issues happening, they still managed to keep things moving and get people in and out as quickly as possible. It also really helped having someone up front directing patients. I didn't catch her name, but she was patient, organized, and clearly knew what she was doing while handling the crowd. I came in for lab work and my 1-hour glucose test, and Kevin did an amazing job drawing my blood. I absolutely hate needles, but he helped keep me calm and made the process quick and painless. Walk-ins are welcome, parking was easy to find, and the facility itself was kept very clean despite how busy it was. Overall, a really positive experience.

    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.

    This was one of the most frustrating experiences of my life. I show up and get checked in. No…read moreissues so far. 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.

    BEWARE: WALK-INS MAX OUT EARLY. I tried doing an employment drug screening, but they maxed capacity…read more2hrs before closing. The worker then told me to go to the Long Beach walk-in location and assured me that they'd accept me there. HOWEVER, after driving all the way to LB, they told me they also maxed out. I tried calling Tustin and Long Beach before driving out but no one picks up the phone. I'm not upset that the capacity maxed out. I'm upset that the worker wasted my time telling me to drive 30min to a different location and assured me that they'd accept me when I specifically asked if that location can max out also. The LB location told me that the Tustin worker had no right to assure me of this and they couldn't help me. Lesson learned: never show up without an appointment because walk ins are impossible. And book your appointment early because they're booked out 2+ weeks in advance.
