Service Description

USCG & DOT Drug Testing for Maritime and Port Workers At LaRoc Precision Testing, we provide reliable and federally compliant U.S. Coast Guard (USCG) and Department of Transportation (DOT) drug testing for maritime and port employees. Whether you’re applying for a Captain’s License or working in a safety-sensitive position, we make the process accurate, confidential, and convenient. What You Need to Know DOT drug tests are always urine-based—hair or instant tests are not permitted. Every test follows strict federal guidelines using a Custody and Control Form (CCF) to document the collection and chain of custody. We also use electronic CCFs (e-CCF) for faster and paperless processing. Our collectors are DOT-trained and complete all required mock collections to ensure every step meets regulation standards. What’s Tested The DOT 5-panel screens for: Marijuana (THC), Cocaine, PCP (Phencyclidine), Opiates (Morphine, Codeine, Heroin), Amphetamines and Methamphetamines, MDMA (Ecstasy) This standardized panel applies to all safety-sensitive transportation employees, including USCG-regulated maritime personnel. Laboratory Process Each specimen is securely sealed and shipped to a SAMHSA-certified laboratory. There are no instant DOT tests. The sample is split into two bottles—Bottle A is tested, while Bottle B is stored for confirmation if requested. Results are reviewed by a Medical Review Officer (MRO) before release, ensuring full accuracy and compliance.
