TSN Mobile Lab Solutions works closely with SAP counselors by providing professional, DOT-compliant specimen collections for drivers who have successfully completed their SAP program requirements and are ready for their Return-to-Duty drug test. Our goal is to ensure that the final step of the process is handled efficiently, professionally, and in full compliance with DOT regulations so drivers can move forward in their return to safety-sensitive work.
