    I have been here nearly 2hours just for a drug test. They seem just to busy and under staffed. Not impressed.

    An English-only section of the waiting room would be nice, a no cell phone conversation would be even nicer.

    My phlebotomist was very friendly and resolved an unclear portion of the lab order without any problems.

    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.

    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.

    On today August 5 my doctor provided me with a lab order, which was downstairs at 2501 E Chapman…read more When I arrived there were many people waiting and I waited patiently. I was lucky enough to have Sherri in drawing my blood and she provided incredible service and patience with a very positive outlook on the whole process. And the reason why I'm writing this review is because I first met Sherry at a labcorp when she first started in Santa Ana where my neurologist had requisitioned 29 vials of blood because apparently I was having some issues. Again Sherry took the 29 vials over a couple of hours putting me at ease and helping me deal with the anxiety. She is an exemplary employee which reflects on the high standards the labcore has when hiring the lab technicians. So had a very positive experience getting my blood drawn.
