    The new world of lab testing centers not an issue for people accustomed to computers but people like my 80 year old mother had difficulties checking in, so she had to call me to come aid her with the checkin process. As there is no front office to assist or a bell to ring for those with questions. Regarding the quality of care the phlebotomy technicians are nice but clients have to wait outside hoping a technician comes out from behind a secured locked door.

    Next to subway

    Happy with the process. Made an appointment online 2 days prior, there were enough time slots available. Even more for future dates. Check in at kiosk, and wait was less than 5 minutes. Had 6 vials drawn by lab tech Phuong, and she did an amazing job. One attempt, no bruising. New location, right next to subway. Tucked in the corner behind Wells Fargo

    This place was only taking 1 person back at a time for hours. Ridiculous.

    There are some people you meet who leave a lasting impression on your heart, and Claire at Labcorp…read moreon Rose Drive in Yorba Linda is one of those people. She is truly one of the sweetest, kindest, and most patient human beings I have ever met. I've always been afraid of needles, but somehow Claire has a way of making something I dread feel calm, comfortable, and even enjoyable. Her gentle nature, warm smile, and genuine compassion immediately put me at ease. She doesn't just draw blood--she cares for people. Healthcare can be intimidating, but Claire reminds you that kindness is one of the best forms of medicine. She treats every patient with respect, empathy, and such a positive attitude that you leave feeling better than when you walked in. Thank you, Claire, for the incredible work you do every single day. You make people's lives better in ways you probably don't even realize. Your compassion brings comfort during vulnerable moments, and people like you are the reason so many of us feel safe. Labcorp is truly fortunate to have someone as extraordinary as you.

    Considering the abysmal reviews for this Labcorp on Rose Drive, maybe I've just been blessed by the…read morelab gods but honestly, I've always had a great experience here. The techs have consistently been friendly, cool, and professional, and check-in is super easy whether through the app or the self-service kiosk. Their waiting area is not bad, it's clean and bright but it does get uber busy at times - so I hope you have an appointment. My personal take - I've learned with ANY lab (Labcorp, Quest, etc.), making an appointment well ahead of time is the real MVP, fortunately, I have not experienced them f'ing up my appointment but it seems they do with some patients. Maybe approach someone in the front desk and kindly bring this up to their attention? It can save you and others from unnecessary frustration, long waits, and the urge to dramatically rethink your entire life in the waiting room LOL. On occasions that you unfortunately you got a same day rush lab order - walking in can be traumatic but miracles do happen like when I walked in at 2:45 PM one time with literally 3-4 people in there or check the app and drive miles away for a location with an availability... or be like Job... we can all practice a bit of patience in a world where everything is in a rush. Cheers!

I arrived at 7:45 AM. I tried to schedule an appointment the night before on the app was told none were available. While sitting here waiting, I checked the LabCorp app again and suddenly there were 9 appointment slots available. That makes no sense. Why weren't those appointments available the night before? To make matters worse, several non-English-speaking patients arrived and clearly did not understand how to use the self check-in kiosk. No staff member offered to assist them. They were left standing there confused, which only added to the chaos and delays. This location is poorly managed, inefficient, and a complete waste of time. I will never return. I finally made it in to get my blood drawn. Veronica helped me and she was very nice. That was the only pleasant experience I had at this place. I truly miss Quest Diagnostics.

Unfortunately, what they lack ends up a longer list. The first MA was unable to get a vial of blood and said someone else would try on my other arm with a straight needed (vs butterfly). She left me without even putting a bandaid on the arm she poked and I had to struggle to put the bandaid on one handed while still maintaining pressure on it. Next MA comes and draws blood and when she's done she yelps I don't have a cotton ball (to put on the vein she just drew out of) and my blood is just pooling while she puts a bandaid on. Luckily I'm well versed enough to know I needed to put pressure on my bandaid. The NP who saw me was new to (per the MA) she really didn't put my mind at ease. Her expertise and knowledge seemed lacking based on the answers to my questions. First thing she asked me was, why are you here and not the ER? I told her my PCP sent me here because she didn't feel it necessitated a ER visit. She wanted me to be evaluated by YOU to assess and in your medical opinion, do I need to be seen further or what course of action next? She swabbed me for flu and covid and I verbally questioned her because I had isolated severe GI symptoms. She said sometimes those present wither GI only. Does it? I don't know, I'm not an MD but I'm also someone who works in healthcare and it didn't feel like the proper procedure. When I asked if she would be ordering any stool samples, I heard through my closed door "do we do that?". Ok, she's new, I'll give her that...but she comes back in and says "if you'd like to have the order for stool testing I'm happy to give that to you." Am I the md or am I the patient? I came here for your professional medical opinion! Do I?! So after I kindly communicated that I am looking to her for her opinion as the expert whether or not my symptoms necessitate an order, she still doesn't quite give me a direct answer! I haven't been to that many urgent cares, but I've come to see a trend that many of the urgent cares that are owned by a company with multiple locations don't have MD's on staff physically there. That said, I've also noticed the trend that many provide sub-par care.

The front desk staff were unprofessional and unhelpful, and my attempts to seek clarification or assistance were not addressed. One receptionist, in particular, spoke to patients in a disrespectful manner. In addition, there appeared to be frequent gossiping between reception staff and a phlebotomist, which contributed to an unprofessional environment. The waiting room was overcrowded, and there did not appear to be an appropriate sense of urgency in assisting patients. The overall atmosphere created unnecessary stress and made the environment feel disorganized and unsafe. Experiences like this can discourage patients from seeking care and undermine confidence in the quality of service. I hope this feedback is taken seriously and used to improve patient care and professionalism at this location.

    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.

    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.

    Every time we come here, we are told they are short-staffed and running behind. While occasional…read moredelays are understandable, this seems to be a consistent issue. Patients make appointments because they are sick, have schedules, and need timely care. Having people sit in the same waiting area for 2-4 hours is not only extremely frustrating, but also unsafe, as it increases the risk of spreading germs. What's even more concerning is that appointment times are not respected. If multiple patients are scheduled for the same time (for example, 10:00 AM), they are not seen in any clear or fair order. It feels disorganized and inconsiderate of patients' time. This level of service shows a lack of respect for patients. If staffing is an ongoing issue, there needs to be better scheduling, communication, and accountability. Patients deserve better--especially when they are not feeling well.
