Return-to-Duty & Follow-Up Testing

Complete SAP case management and follow-up testing coordination. From referral and treatment verification to RTD scheduling with milestone tracking—we manage the entire process.

The Return-to-Duty process requires SAP evaluation, treatment completion, a negative RTD test, and minimum 6 directly observed follow-up tests over 12 months. Missing a test or failing to report milestones to the Clearinghouse triggers new violations that restart the entire process.

DSC manages complete RTD programs with our $250 SAP case management service: SAP referral coordination, treatment verification, RTD test scheduling immediately after SAP clearance, directly observed follow-up test coordination, automated reminders before each deadline, and Clearinghouse milestone reporting. Individual tests are $85 mobile or $60 clinic (directly observed as required). Get drivers back to work safely with proper coordination and documentation.

Frequently Asked Questions

A minimum of 6 directly observed follow-up tests must be conducted over 12 months. However, the SAP may require additional tests and extend the follow-up period up to 60 months based on their clinical assessment.

If a driver tests positive during follow-up testing, they must be immediately removed from safety-sensitive duties and the entire RTD process begins again, including SAP evaluation, treatment, and a new follow-up plan.

Yes. All Return-to-Duty and follow-up tests must be directly observed collections, meaning a same-gender collector directly observes the driver providing the specimen. This is a non-negotiable DOT requirement.
