We are both cancer survivors and have to get blood works frequently, I'm grateful daddy is in the WH, I was paying $900 a month premium a month so Newsom can give free health care to migrants. Don't let anybody tell you otherwise, things are getting better since 11/5/2024. I have changed Quest Diagnostic many times, this one is the last time I have to do so, the worst one is next to Fountain Valley hospital, the wait was up to 1 hour, the room was full of migrants they probably had TB or other pulmonary diseases, they coughed their brain out and I was fearful we would both die from caching TB as said above, we are both immunocompromized, btw keep our health care excellence, most cancer patients are dead in Canada, in America you die w cancer and rarely die OF CANCER. The 3 Quest offices in and near OC Memorial hospital, the wait was ridiculous up to 40 minutes maybe 15 min w appointements and you spend 25 minutes looking for parking, this office has been here for years, I can't understand why I never thought about coming here. The tech was quiet but she did her job, it's Ok, I don't need to chat, just get my blood work done and get out fast! I'm totally shocked the results were in 24 hrs, it used to take a week and it was like pulling teeth, I had to call them to demand my results, geez, what was their problem so trust me, my reviews are 100% accurate, the good, the bad and the ugly, I never sugarcoat anything. I'll post this on Google soon, it's not fair the low rating hurting their business. Everything is cool except my A1C, I have been eating too much rice with HAINAN CHICKEN 3X, I usually don't eat rice, bread chocolate, I don't like starchy food in general but the glutinous rice in rice cake killed my A1C, I have to stop any more Hainan chicken rice or I will get diabetes. The parking here is great, plenty of parking, altogether I saved 1 hour coming here.

Took both my kids (aged 10 and 12) in to get their blood drawn. Upon entry, we checked in, and the…read morekiosk requested for us to scan our insurance cards, which I didn't have on me. I asked one staff if it was possible to check in without the insurance card and if they had it on file. She was rude and dismissive but I didn't let it bother me, as it was 7:40am and I'm sure the staff are tired and busy. When it was time for my 10 year old to get his bloodwork, the plebotomist named Zenaib, sat him down and didn't greet any of us. No simple hellos, no smiles, no words of encouragement. Given that children are nervous to get blood drawn, you would think she'd cared a little bit to be gracious in her demeanor. It doesn't end there... She inserted the needle and couldn't find the vein and started FISHING around his vein with the needle. My son was already crying after she fished for the vein 6 times. She didn't care. Again, no words of encouragement! She moved the needle around under his skin NINE times!!!!!!!!! I had to intervene and told her to stop. Had I not, I'm unsure how much longer she'd fish around! Once she took the needle out, she didn't even address my son (who's profusely crying), nor did she give me any directives on next steps. I requested for someone else who's more experienced with the "little ones". The other Plebotomists indicated that they're all "trained" the same, in which I highly doubt. At this point, I had to remain super calm (and nice), despite the frustration, as I wanted my son to have a successful blood draw after the first fiasco. Rita, who drew blood from my daughter attempted one time successfully, so we requested for her to try my other son's arm. She wasn't the most personable person either, but at least she got the job done successfully on one try. I asked another Phlebotomist on the way out how many times they typically fish for a vein before they stop and she told me three. Only THREE times!!! It blows my mind how Zenaib would fish NINE times!!!! Yes! I counted! I would greatly despise that experience for myself, much less for any child! Only 1 out of the 3 Phebotomists here are friendly and personable. Is a smile and a hello hard to come by nowadays? I don't need it as an adult, but when children come in, I'm hoping they would be more gracious to them in the future. I personally would not be back to this location (heck- I may even stop going to Quest in general). If you do go, avoid Zenaib, especially if you bring in your child.

Checking in was a breeze, they have self service kiosks. All questions and directions for a new photo of ID and insurance card were pretty straight forward. I made an appointment for 10:10am and was helped out pretty quickly after my arrival. Appointments are available to make online, walk-ins are welcome but there will usually be an extended wait. Blood draws haven't always been easy for me, but over the years I've been able to hop that mental hurdle. Even then, my heart always beats a little bit faster when I enter a lab. I was greeted and helped by Samantha, a most kind human and wonderful phlebotomist. I think she could sense my nervousness and kept the conversations flowing. She answered all my questions and was super patient. Most importantly she didn't hurt me and she got me on first poke. YAY! My doctor had requested a blood draw and a urinalysis. I recieved an email that my general labs were ready next day. Quite quickly, especially when they average 2-5 days! I did have a specialty/genetics test that promised results in 2 weeks or more. I recieved them right in the 14 day mark! I appreciate the punctuality! From my experience, this is my favorite lab to go to when I need my labs ran. Will be back! Side note, as of right now (April 2026) they are re-doing the parking lot, adding solar panels and coverings. I'm assuming the project goes into the fall. Parking has been crazy. My primary care doctor and women's health doctor share the same lot, it has not been fun trying to park. I'd come at least 15 minutes early!

She was required to fast before the appointment, so we came early in the morning before school. We waited almost 3 hours in the waiting room. When I finally asked what was happening, the staff told me they had skipped my daughter because they did not know how to pronounce her name. No one had called us or tried to ask. Another major issue was communication. The receptionist did not speak English, and no one in the clinic seemed able to communicate with us in English. This made it very difficult to ask questions or understand what was happening. After the labs were finally done, I asked for a simple doctor's note for my daughter's school since she missed the morning due to fasting and the appointment. The receptionist said she did not know what that was and could not provide one. Overall, the long wait, lack of communication, and inability to provide basic documentation made this a very stressful experience for both me and my daughter. I wish I can give it 0 stars .
