Assured Drug Testing Services provides complete DOT or non-DOT random drug testing program management through our partnership with Doctors Review Services (DRS). Assured clients have complete and secure access to their random testing pool rosters and have the ability to add or delete employees from their random testing pools through a secure website. Random lists are generated quarterly in accordance with DOT standards or at a frequency and random testing rate that the client prefers. Testing selection reports and notification letters for the employees are provided to the client and compliance is tracked through drug testing results actually received from the laboratory.
