I had an appointment right before lunch, I assume they get backed up as the morning goes on. I got there 10 minutes early, signed in, nobody at the reception area, no problem. I sit, 5 min after my appointment time the woman asks to take my paperwork. 10 min after that she takes me back for a drug test. I peed in a cup. Friendly service, clear directions. This location takes walk in, but prefers appointments. I reserved my appointment online through their website. This seems to be how the majority of their customers make an appointment. Remember to bring your ID. I like Quest's setup better than Labcorp because they didn't make me sign a paper that says I agree to pay what the insurance doesn't. I don't like agreeing to things that are unknown. Find this location by parking alongside the building and going in the entrance in the middle of the building, the tinted window doors. Then turn left, go to the end of the hall, then right down the long hall and down the ramp. You'll find Quest's door on the right. read more

Quest Diagnostics - Sign in... - Laboratory Testing Near Me - King Of Prussia, Pennsylvania

I was there on 7/24/26 to get blood work done. The technician I had could not even find my vein in my arm to draw the blood. Then she got mad and frustrated when I asked her if she knew what she was doing and then she called me ignorant for asking her that!!! She couldn't find the vein in my arm. I advise anyone do not go here. Go to another location if you have to deal with Quest. Do not go to the East Norriton office. I filed a complain with Quest. They probably will not do anything about it. Go to another location if you need blood work done!!!!! read more

The employee for Quest that I had the misfortune to deal with was DeNea. She had the manners and mannerisms of a Water Buffalo . Short tempered and snorty. There is obviously no screening of the staff for human to human interaction skills. I'll never return here again. read more

Horrible facility. Looks like someone's broom closet. Never told me that my insurance didn't cover the multiple tests my daughter had done there. Now I need to foot a $1400 bill. They don't have an NPI number, which I thought every medical facility needed to have, so I can't try to get anything out of my insurance company. Quest does not listen to your concerns, and makes the same mistake over and over again. Horrible company. Now I know why IBX doesn't have them in their network....which I'm now learning. read more

I am pissed!! I just waited 35 minutes to take a drug test for a volunteer job. When I am finally called back, Barbara informs me that the restroom is out of order and I would have to go to Norristown!? Seriously if it is out of order you need to let people know right away, why did I just waste 35 minutes and my lunch hour!!! I stated that there is a restroom in the hallway and she's like oh we cannot use that because it breaks chain of custody. I don't give a crap if you stand outside of the damn door this is just ridiculous. I'm LIVID NOW I'M GOING TO HAVE TO DO THIS ANOTHER DAY read more

Barb and Kea took wonderful care of me in a timely basis. I had a lot of questions that they did not have to research but they did. Kea is painless! Thanks for everything read more

Went in for an employment drug test and was treated unprofessionally. The lady ordered me around doing unnecessary tasks such as washing hands then going outside grab a test cup, taking off your jacket when I don't need a blood test, closing doors behind you... being passive aggressive at its fullest. I have been to different places and this is the first time I've come across someone like her bossing people doing tasks that she supposed to do. Very disappointed in how she treated client. Not sure what she can get out of this dominance. read more

I can't stress enough how badly this location is run! The employees are friendly and good at their jobs, but they are not staffed sufficiently and the computer system makes the wait time estimates laughable!!! We waited over 90 minutes for my son to get a blood draw and never got an accurate estimate of the wait time. Stay away!!! read more

Very late getting me both results on my COVID tests. Billed me $100 for the free tests. Website and Quest phone systems give you the runaround. Website says "you gotta call us for that info" person on the phone says "you can only find that information on the site" incredibly unhelpful but not surprising. Choose LabCorp. EDIT: Thanks for replying Quest. Thanks for sending me the same phone number I was complaining about in my review above. A+ automated response. Really shows you're listening to the customer. read more

How awful of your business to not provide masks to your patients. If a patient forgot their mask, they refuse to give them one! How unprofessional! Bad business practice! Some people travel a long distance for their appointment and you are going to turn them away?!? I never heard of this. Shame on you Quest! Dear God, out of the kindness of your heart, give them a damn mask! Don't we have enough problems right now?!? These are the people keeping your business open. read more

Would give zero stars if that were possible. Arrived a little before 2:30 pm. Sign says they are open until 3:30 pm. There was nobody in the waiting room or on the waiting list, for that matter. We figured the staff was helping someone but soon heard them chatting with each other in the back about smoking cigarettes. My boyfriend made some coughing noises, we jingled our keys and started speaking loudly to let them know there were people that needed to be helped. Nobody came up. Two more people came in during the 20+ minutes we sat waiting for them and they still didn't come to help anyone. Absolutely ridiculous staff. So unprofessional. read more

I need to get some blood work done and my phlebotomist, Kristie or Kristi was amazing!!. She makes the whole process extremely painless!!.

If I could give it Zero Stars I would!! Went there on a Friday at 6:30 am-Wasn't seen till 7:20 and I was the third person there. The unprofessional, rude woman let 3 other people ahead of me. Not only did she laugh and joke with everyone else, but as soon as she got to me she was so rude and unprofessional! Was it the color of my skin or because I wasn't white? Which one! She spoke and laugh to everyone that was white and when she called my name---- Ignorant isn't the word and I hope she is reading this! I would never go back to this place and would not recommend this one in particular! WORST SERVICE EVER! read more

Professional courteous service. In at 7:30 without appointment out by 8:15. Only one phlebotomist, but she kept things moving. Note that the suite has changed to the first floor. read more

Worst service ever! I will never go back to this location. When I walked in greeted the lady -Michelle at the desk she replied did not even look at me. I signed in and waited patiently. At this point I was very excited that there was no one here. I expected the place to be packed and a wait time. The lady asked me to approach her. She very rudely asked me for my insurance card when i presented the lab order to her. Also maintaining no eye contact. Then she asked me if my address was correct because her screen was showing an SF address. I told her I wasn't sure why that was coming up and got worried. As I spoke to her she continued to stare at her screen and ignore me. She wouldn't respond to anything I would say to her and demand answers to her questions. At that point I got nervous and asked her about the details of my test. She looked at me with a "really?" Expression on her face then ignored me and looked away. Then she said have you been to us before? I said not this location no. Then she responds very rudely "have you been to quest diagnostics in Pennsylvania period!" At that point I was sure she had an attitude with me. She directed me to the room and left me there for 10 mins. When she returned she asked me to drink a liquid. I was very nervous and I asked her what it was and she ignored!! What the heck is this? Why couldn't she tell me about what was about to happen. And after 10 mins post liquid episode she calls me back by pointing at me from afar as "you" room two ! Awful! I'm never going back period! read more

This was a terrible experience at the King of Prussia, PA location. We have used Quest for several years now and never encountered anything close to this. Don't even think about being a walk in because they will put anyone who comes in with an appointment, even if they are significantly early, ahead of you. The staff was not pleasant and explained as a walk in you will be put behind anyone with an appointment. It felt like they were trying to teach us a lesson to make an appointment by punishing us and taking any appointment ahead of us first. Why wouldn't they try to work the walk ins at some point, instead of expecting them to just wait endlessly? Why not just say by appointment only on their website, that would be more honest and correct and helpful to people? We won't return to this location and will try to find some other medical testing company besides Quest. No one deserves this kind of treatment, we finally left, we could have ended up waiting all day! read more

Worst service ever! I was told that I did not need an appointment because I had a doctors order from my doctor. All I needed was some blood work. This lady literally look at my 3 times and took 3 people who I came before. Now I am going to be late for work. read more

HORRIBLE SERVICE. I was sent to this location through a company I am newly employed with for a drug screening. I was hoping it was going to be a quick in and out appointment.. Didn't work as I had wished. The receptionist was extremely rude, she threw the sign in sheet at me along with every other patient without a hello or good morning. I had to wait a whole 45 minutes until I was helped. I was unable to get enough pee to fill the cup to their standards, so I was sent to the waiting room not once but TWICE to drink water. 10 glasses of water later and my third time with the drug screening I was able to fill the cup to their standards. I thought everything was good and I was glad to get it over with just to find out that it was too diluted and I was likely to have to go back. The doctor along with the other workers were very cold and unfriendly. I am an extremely easy going person, however I ended up leaving that place without saying thank you due to the horrible service that I received! If I could give this place a negative 10 I would. read more

Geez I'm so sorry to hear that some of you had a bad experience at Quest. I have been going there since Jan. on a monthly basis and have always had a pleasant experience. The BEST part is the ladies are so experienced that it never hurts! read more

Absolutely worst "service" I have ever encountered! There was no one at the front desk when I arrived for an 8:45 appointment. After an half hour wait a lab technician appeared, asked for (demanded) my insurance cards, paperwork, then ordered me to Room 4. (Not so much as a "Good Morning, Please, Thank You, a smile or any eye contact.) Another wait, then she reappeared and laboriously started to enter the info for my tests on the computer wearing her gloves, not sure how sterile she thought they would be after wearing them all morning. A second technician appeared to take over, all entries were deleted and she proceeded to re-enter the info under her name. She had difficulty determining the codes for some of the tests so had to consult with the first person. I have never seen such slooooow data entry. After a "straighten your arm" she drew my blood. Still no pleasantries or even recognition that I existed beyond my arm. I was then given the specimen bottle for a urine sample and I had to ask where the rest room was. She pointed down the hall. The rest room had no soap to wash my hands to prepare the specimen; unbelievable in a place which should emphasize cleanliness. I placed it on the counter where there was another one and left. It took them way over an hour to do a simple blood test, ridiculous! The waiting room was packed when I left. I could only feel sorry for those waiting as those techs were so slow and inept I couldn't see how they could possibly finish with their testing before the lab closed. Who interviews and vetts these people? read more
