Medical Review Officers

The Medical Review Officer (MRO) field is complex and rapidly evolving due to technical advances, regulatory changes, and new patterns of abuse. Testing for substances of abuse is now the rule rather than the exception in settings as diverse as the workplace, the doctor's office, and many schools throughout the country. The Drug-Free Workplace Act affects all federal agencies. Mandatory alcohol and drug testing is now required of all intrastate truckers, commercial driver's license holders, and other transportation workers. Joint government agreements between the United States, Canada, and Mexico monitor truckers crossing international borders. Federal regulations require MRO qualification and re-qualification training followed by certification and recertification by a nationally recognized Medical Review Officer Certification board every 5 years.
