1045 am, October 02,2025…read more I pulled in the medical plaza thinking I was barely making my appointment and looking for a parking spot! I found a couple but it was for the building next door. I proceeded to park in the spot thinking I was going to be in and out of here! Oh no, was I wrong. The LabCorp was packed! And then I checked my appointment time... Holy cow! I'm an hour early. Phew... I rush back out and decided to move my car. I did not want to be towed. So, your options for parking are 1) Parking structure, 1st 30 minutes free, beyond is $1.5/30 minutes. 2) There's street parking available on Valencia Mesa. Short walk to the building. I do the express check-in via the mobile text received but also at their kiosk as I wasn't sure the phone method worked. At the kiosk, you'll need to scan your DL. All checked in, it said that I can go wait elsewhere that I'm comfortable. Heck yes, get me out of that cramped waiting area. Ridiculous... I'm sitting on the bench just outside of the building entrance doors writing this review. It's much nicer out here with fresh air. Getting nervous, ten minutes past the appointment time... Ooh, the text messaging worked but back to the receptionist to confirm information and lab orders. Back to waiting again for next available phlebotomist. This waiting room is way too small, way too many people. Finally, I get called, 30 minutes past the appointment time! I'm not surprised. SMH. The phlebotomist is nice, however, I judge them on their skills for drawing blood. I will let this experience slide... WTF are you going to do? She couldn't find a vein, I guess I need to chop off the defective left arm! Haha! She asked to use the other arm, how kind that she asked. As I said, what are you going to do? Reschedule? Hell no! My time is valuable, #JUSTDOIT. She was able to get the vials done. Her wrap on the left arm comes undone and unravels. C'mon now. Greenhorn, a little inexperienced, or just cheap not using enough stretch bandage?? All done except she presents me the little cup for the sample! Haha, fine, this one is no problem! If you are unfamiliar with location, I highly recommend you go to a larger location or at least call to talk to one of the staffers to ask about their slow and busy times. I know this area so parking on the street isn't an issue. I've never experienced such a busy and tiny LabCorp location. Even the phlebotomist said it's their smallest location in the area. Oy vey... My phlebotomist did her best to care for me, she was gentle, but strike one was the big miss. Strike two was not bandaging properly. These are on her. The facility is too small for my liking. I'd choose another location and will only return if I had no other options.

1015 am, January 02, 2026…read more First of all, bring ID & insurance card. I forgot my wallet in the car went back and retrieved it. Only one electronic kiosk was available out of 5? Thankfully, there weren't any other patients in there. Only one patient was being seen for his labs and he finished when I completed my electronic check in. The receptionist/phlebotomist asked the doctor name to ensure that they have the lab requesition orders in their computer. Everything went smoothly. I was immediately asked to go to station 1. A male phlebotomist handled my blood draw very well. The needle injection was painless and went very smoothly. I was told that I had just missed their morning rush of patients! So I am assuming that it's best to avoid the early hours of business here. There are plenty of parking spaces at this old medical building here on Imperial Highway. I was finished in about 15 minutes.

I imagine you're pretty busy and don't want to be bothered with people who are capable. I got a guaranteed line at 11:15 and when I arrive there was seen within 5 to 10 minutes.

715 am, Saturday, May 16, 2026…read more I came an hour early to the Quest Lab to find out if they'd take me early before my appointment time as a walk-in. Not sure if it'll happen as I already have the standing appointment. The self service kiosk is easy to use, there are four machines near the entrance. Plenty of parking spaces here at the medical plaza. There's a constant arrival of patients, so not likely to be seen earlier than the appointment time. I have no idea when walk-ins would be seen as appointments have priority. I don't recommend trying to get here any earlier than ten minutes. The restrooms are clean, however, there's no wall mounted soap dispenser. That's such a big miss! Super silly having that gallon sized pump hand soap on the cabinet away from the sink. The hand dryer works well, there are no paper towels. This one is weird too, I was given a small plastic double Dixie cup with lid instead of the medical grade plastic urine collection cup. Hmm... Not sure if that was because I had to go before she had a jar ready and labeled. My phlebotomist was professional, yes. But she wasn't as good as the other one I had previously. All I care about is that they're able to collect the blood sample on the first insertion of the needle. Don't miss! Haha.
