Drug Testing
in Colorado

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.

I thought it was extremely easy to book a lab test appointment with Quest. Getting the test done was simple and so was the getting the results! Great job putting together something so user friendly.

Great discreet service, scheduled my visit and paid for for the test online not in Showed up at lab, checked in and was seen within minutes. Blood and urine were collected, test results came back quickly within 2 days because I did my test on a Friday. Quick, easy and cheap. Didn't have to wait for a visit to my PCP, and then get referral to lab.

I highly recommend for anyone thinking of getting tested. From start to finish the whole process was hassle free and and very professional. I had my results very quickly and discreetly couldn't be happier with the service.

I was very surprised with my experience here. My appointment was made very quickly. I was seen in a very short period of time. My test results came back in a very timely manner. I was able to speak with a doctor soon after and was taking care of. I was very satisfied with the experience I had here. I definitely recommend using them for any issues you have or any questions you may have.

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 would 100% recommend this company to anyone wanting to check their health status. The process was incredibly easy and done through certified labs. The results are frequently back by the next day.

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 had two test kits to get blood drawn for- the whole process was quick and thorough and despite a lifetime of difficulty finding my vein- Shannon had absolutely no trouble whatsoever.
