Customer Reviews

Friendly and Knowledgeable

I reached out Accredited Drug Testing/Secure Screenings to partner for my drug testing business (Discovery Diagnostics Columbia SC) and the process was extremely easy. I worked with Sicilia who was amazing. She was friendly & knowledgeable, and answer all of my questions with ease.

Kendra Harley - 3/26/2025

Everything was great

Everything was great, the staff was very polite. Thank you.

Olga Petrova - 9/19/2024

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.
