Accredited Drug Testing also offers non-legal DNA testing. This option still compares DNA profiles but does not require the same level of identity documentation or chain of custody. These results are for personal knowledge and are typically not intended for courtroom use.

Customer Reviews

Super Helpful

Detricia was super helpful in making sure that the drug test is sent my worker for was the right one I needed for my company to be compliant with my customers drug test requirements.

Kevin Howell - 12/19/2024

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.
