A great experience for something I had a lot of anxiety about. Had no wait time or issues at the testing center/lab. Had blood drawn at 3pm and had results by email at 9am the next morning.

I was able to choose a Quest lab location and schedule an appointment. Check in was easy, and I only needed to provide my name and DOB. They were able to locate my order in their system. They were already aware that my labs were paid for prior to the appointment. I had my labs done on a Wednesday, and I received my results by Saturday. Great experience.

I came in one day without an appoint and waited two hours as a walk-in before I had to leave without being tested. I made an appointment through Quest Lab Testing for the next day, showed up on time, got tested easily and was on my way in 15-20 minutes. Staff is friendly and helpful.
