Non DOT & DOT Urine Lab Tests


Non-DOT urine tests, unregulated by the Department of Transportation, are employed by organizations for drug screening, such as pre-employment checks and medical assessments. In contrast, DOT urine tests are highly regulated and required for safety-critical roles in transportation sectors. The key difference lies in the level of oversight and the specific set of drugs tested for in these screenings, ensuring safety and compliance within the transportation industry.  Common substances tested for in these tests include Marijuana (THC), Cocaine, Amphetamines, Methamphetamines, Opiates (e.g., heroin, morphine, codeine), Phencyclidine (PCP), Benzodiazepines, Barbiturates, Methadone, Propoxyphene, and Synthetic opioids (e.g., fentanyl).
