MERCHANT MARINERS MEDICAL EVALUATION

Merchant mariners are required to have a medical evaluation performed by a licensed medical doctor.  As part of the medical evaluation, a DOT (Department of Transportation) drug test is usually performed.  This drug test can only be performed at an approved facility that uses federal CCF (Chain of Custody Forms). In addition, a SAMSHA (Substance Abuse and Mental Health Service Administration) approved laboratory, as well as a certified MRO (Medical Review Officer), must also be used.
Professional Occupational Health Clinics are recommended for both the physical exam and drug screening because of their familiarity with the professional requirements of these exams.
