Saved My CDL!
Time was running out before my Cdl got downgraded because of a violation I had on clearinghouse. I couldn't find an employer to send me for my return to duty test, but these guys had my test scheduled and done in the same day! They saved my cdl. Thank you again!

This is by far the easiest
This is by far the easiest way to get my lab work ordered and paid for. The phone calls are short and to the point. They don’t try to push extra sales on you and when I walk in to the clinic I simply show my donor pass and with in a matter of minutes I’m done. I will continue to use ADT in the future.
Jason Jackson - 7/19/2025

I was so surprised with the quality of customer service I received today when I called Accredited Drug Testing. The representative was so clear and competent. She was able to reschedule an appointment at my preferred location. The representative whose name is Justice, was so polite and competent. She expedited the whole process. It was a relief to me.

ADT was able to get me the best tests
Dealing with allegation’s of drug use that completely false is stressful, ADT was able to get me the best tests, going back the farthest in the same day with as little hassle as possible, I spoke with 1 person and wasn’t transferred once, and they took my payment, and got me my work order for a clinic as close as possible for the service I needed. 5*
