Frequently Asked Questions

On-site drug testing means a certified collector travels to your workplace, job site, accident scene or other location to perform drug, alcohol or DNA tests, rather than sending employees off-site. The testing event uses urine, saliva or hair specimens (depending on panel), and can include breath alcohol screening. Accredited Drug Testing offers this service 24/7 nationwide.
Industries that commonly use on-site testing include construction sites, manufacturing plants, power plants, motor pool facilities, car dealerships, trucking/transportation companies, schools, hospitals, and oil & gas drilling sites.
Available test types include urine drug panels (5-panel, 10-panel, etc.), saliva/oral fluid tests, hair follicle testing, rapid/instant screening and breath alcohol testing (BAT). For DOT-regulated employees, full chain-of-custody and DOT-compliant documentation is provided.
Key benefits include convenience (the collector comes to your location), minimal downtime for employees, faster response especially for post-accident or reasonable-suspicion testing, and improved compliance because the service provider handles certified collectors, forms and documentation.
When scheduling, you’ll specify number of people to be tested, location, time and type of tests needed (DOT or non-DOT).

Where do I start?!! ADT is truly the best!! I had the pleasure of speaking with Tori today! She was excellent, professional and truly went above and beyond in her kind, compassionate care and commitment to providing me with the best service possible.

Fantastic experience from the beginning. Jocelyn was very helpful to me as someone who doesn’t have much experience in needing a test. They were very helpful and walked me through the entire process start to finish. Thank you ADT!

Super helpful and courteous

I've had to use this service twice for out of state physicians we've hired and both times it was super easy. Both customer service reps I spoke with were super helpful and courteous. I won't hesitate to use their service again if needed.

Alicia Rau - 6/19/2024

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.

Jason Jackson - 7/19/2025
