    Everyone was kind and helpful. The guy that did my blood draw was excellent. Usually takes multiple sticks but not this time.

    I was in and out of there in an approximately 15 minutes. The check-in process was very easy to complete. The technician did a very good job at drawing my blood. I have no complaints.

    The parking situation here makes everything a lot more stressful than it needs to be. I have to lay down for 10 minutes after getting blood drawn so I don't pass out, and there's only 30 minutes of free parking, so if I arrive early to my appointment as recommended and lay down after as recommended, there's like 10 minutes left for me to get to my car, drive to the exit, and process everything. So now I'm having to choose between literally fainting and getting cold sweats / nausea and paying $4 for going 2 minutes over their 30 minute free limit. So dumb and needlessly stressful to extract a few bucks out of patients. I wouldn't go here if you can't immediately stand up after your blood draw and get out. The building is also renovating an elevator so you're wasting another 5-7 minutes of your limited free parking time waiting to get to the office in the first place. God forbid you have a walk in appointment...

    Writing Today I went to get a blood test done for my 11-year-old child after a visit to the pediatrician. When we went to the doctor, there was a suspicion that he might have pneumonia, so the doctor told us to go get blood tests as soon as possible so they could understand what was going on. Besides my 11-year-old, I also had two other children with me — one is a year and a half old and the other is three. I went into the Quest laboratory, showed them the paper where the doctor clearly wrote that the tests needed to be done as soon as possible. They acknowledged it. In the end, we were called in only after an hour. I understand that usually you’re supposed to make an appointment, but this was not a situation where I could realistically schedule one, especially since their appointments are booked a week in advance. At the very least, there should be some basic human understanding when someone comes in with small children. Eventually my younger kids started crying and disturbing the other visitors — which is completely understandable in that situation. But the staff seemed to care absolutely nothing about the fact that I was standing there with three children waiting, or that the doctor’s note clearly said the test needed to be done as soon as possible. And after all that waiting, the employee couldn’t even draw the blood. She said my child was dehydrated. Yet somehow in other locations, or with other staff, they manage to draw blood without saying he’s dehydrated. A friend of mine had the same experience at this location — they couldn’t draw blood from her daughter either. I don’t know if it’s incompetent staff or something else, but this place is honestly just a complete mess.
