    Just want to write this for anyone fearful of needles like me. I had a great experience here so I…read morewant share that this place is very good and I recommend it for anyone with medical anxiety. I like it here because it's not a doctors office so it lowered my anxiety. I was shopping for seasonal decor while waiting for my name to get called. Once my appointment started the nurse kept chatting and making small talk- I could tell it was to keep me distracted from the needle and it worked :) I'm sure it depends on which nurse you get but my blood draw was basically painless and they took a lot of blood too. (I think my nurse name was Esther?, she was very skilled and so nice) I made an appointment and even though I was a couple min late they saw me within like 2 min of me checking in. I would recommend this location and come as early as possible since you can't eat food before the test.

Today, I experienced it firsthand, and it was extremely embarrassing, especially with the other two employees sitting there watching. I understand that paperwork and procedures have to be followed. What I don't understand is why a customer needs to be spoken to in a loud, confrontational manner. There is absolutely no need to raise your voice at someone when you can calmly explain what is needed. I came in expecting a routine experience and instead left feeling embarrassed and disrespected. Customer service should include basic courtesy and professionalism. I hope management addresses this because no customer should be made to feel this way

Doc recommended any Quest…read moreDiagnostics location so I visited the Corona location since it the only nearby that's open on the weekends. I didn't think they would be busy since they close at 12 but I was wrong LOL. I came in at 11 and saw that there were literally 20 people ahead of me. Despite this, I was promptly seen within 15 minutes. The staff were hustling! Now the real purpose of this review is to commend Candice for her exceptional care quality and professionalism. 1. I never felt a thing when she poked me with the needle. 2. She was completely finished with me in under a minute. 3. She was so polite and prompt My experiences with similar places have varied. My experience with Candice was so painless, reassuring, and pleasant. I'm not scared of needles but Candice is certainly someone I'd recommend for anyone who is. Especially for kiddos. Overall, my experience was great. I was in and out! Thanks Nurse Candice!

My partner & I were there for routine blood and urine tests that had been ordered by our doctor. We had an appointment at the same time. Before we even checked in, a friendly staff member who was calling someone else answered our question about whether they would take a urine sample there or we had to bring it. They would take it there. My partner checked in on his phone and got instantly called in. I checked in on their screen and had to wait in the queue for 5 minutes. The women who saw us, Briana and Andi, were friendly & professional and took our blood with no pain. We were in and out in 5 minutes. Now looking forward to seeing our results on MyQuest. A really well-run facility! Upstairs from an urgent care place and several wellness businesses.

I always enjoy returning to this location because of it's highly organized, clean, warmly hospitable, and quick and efficient Service. It is very easy to set up and change appointments online, and I love how I can check in easily through my phone and wait in my car if there are no seats available inside Walgreens! My appointment was at 1:00 on a Thursday and the Lab Techs were very courteous and punctual with calling me in on time! Nisha was dressed in a clean and fresh white Lab Coat and communicated very thoroughly and clearly to make me feel like I was in the hands of a qualified and trustworthy Professional. Inside the Lab was clean, inviting, and clutter free and Nisha was attentively kind and sharp enough to notice slight inefficiencies with the paperwork and tidied up the processes to make sure I didn't have to take out more blood than necessary. Nisha was friendly, warm, and easy to talk to and was able to find my vein quickly and wrapped up my arm with clean and fresh cotton balls and gauzes. She gave me a small paper cup and instructed me leave a small urine sample in the front for Delfina, who was also very professional and locked into her Hustle and communicated in a confident and courteously efficient rhythm. Miguel was nice and welcoming as well and overall my experience with the Eastvale Walgreens Labcorps was easy, enjoyable, and exceeded my expectations in cleanliness, hospitality, and speed of service! Keep up the good work!!

Of course I did set an appt a day before on the website. It was easy to navigate and make an appt. The staff working on August 23rd, 2026 were awesome and super sweet! On top of my 5 star review, i'm so thankful that several months ago I was struggling with muffled hearing. I had been there many times and the doctors had exhausted all options for treatment from steroids to antibiotics. They suggested that I go see an ENT.

There have been times when the wait was long, even with an appointment, but other visits have been quick. Regardless, the wait has always been worth it because we've consistently received great care. It's hard to find a place you trust for your family over so many years, and we've always been very happy with the care we've received here. Highly recommend!
