DOT drug testing requires urine specimens to be analyzed at a SAMHSA-certified laboratory. All non-negative results are reviewed by a Medical Review Officer (MRO) before a final result is reported to the employer.
We administer compliant drug testing programs for employers regulated by all six DOT agencies.
Federal Motor Carrier Safety Administration — commercial drivers and motor carriers.
Federal Aviation Administration — aviation safety-sensitive positions.
Federal Transit Administration — public transportation operators.
Federal Railroad Administration — railroad employees in safety-sensitive roles.
United States Coast Guard — maritime industry regulated positions.

Required testing after qualifying workplace accidents — alcohol within 2 hours, drugs within 32 hours for FMCSA-regulated employers.
Required when a trained supervisor has reasonable cause to believe an employee may be using prohibited substances.
A negative return-to-duty DOT test is required before an employee resumes safety-sensitive duties after a violation.
Ongoing unannounced follow-up tests as prescribed by a Substance Abuse Professional (SAP) following a return-to-duty evaluation.
The Medical Review Officer (MRO) is a licensed physician who reviews all non-negative laboratory results before a final report is sent to the employer. The MRO process is a required component of every DOT drug testing program.
When a laboratory reports a non-negative result, the MRO contacts the tested individual to determine whether a legitimate medical explanation exists — such as a valid prescription. After reviewing all relevant information, the MRO issues a final result of negative or positive to the employer. This process protects employees with legitimate medical needs while maintaining the integrity of the testing program.
