Medical Review Officer (MRO) drug testing is a specialized part of workplace substance screening. This process involves a licensed physician, the Medical Review Officer, who independently reviews laboratory drug test results. The MRO acts as a crucial intermediary, interpreting medical information and laboratory data to determine the final, verified test outcome for an employer’s drug testing program. This approach ensures accuracy and fairness, providing an objective medical perspective.
Role of the Medical Review Officer
A Medical Review Officer is a licensed physician with specialized knowledge in substance abuse disorders, serving as an impartial party in the drug testing process. Their primary responsibility involves reviewing all laboratory results from an employer’s drug testing program. This includes confirmed positive, adulterated, substituted, or invalid test results, ensuring proper procedures were followed. The MRO evaluates potential medical explanations for non-negative results, such as valid prescriptions or medical conditions.
The MRO also reviews chain of custody documentation to confirm the integrity of the specimen from collection to laboratory analysis. This review safeguards against procedural errors that could compromise the test’s validity. They are tasked with protecting the confidentiality of drug testing information, handling sensitive medical data with discretion. This comprehensive oversight helps to ensure the reliability and defensibility of drug test outcomes.
The MRO Drug Testing Process
The MRO drug testing process begins when a laboratory reports a non-negative result to the Medical Review Officer. Upon receiving such a result, the MRO initiates a verification process, which includes attempting to contact the donor directly to discuss the findings.
During this confidential interview, the MRO provides the donor an opportunity to offer a legitimate medical explanation for the non-negative result, such as a valid prescription for a detected substance. After reviewing all available medical records and consulting with the laboratory if necessary, the MRO makes a final determination, classifying the result as verified positive, negative (if a legitimate medical explanation exists), or cancelled. The MRO then reports this verified result to the employer, without disclosing specific medical details unless directly relevant to safety-sensitive duties.
Importance of the MRO in Drug Testing
The Medical Review Officer’s role ensures the fairness, accuracy, and legal compliance of workplace drug testing programs. MROs provide an objective medical review, preventing adverse actions against employees based on false positives or legitimate medical reasons. This protects employee rights and maintains privacy by handling sensitive health information confidentially.
MROs also help employers navigate complex federal regulations, such as those established by the Department of Transportation (DOT) under 49 CFR Part 40. Their expertise ensures drug testing procedures adhere to these guidelines, which is significant for safety-sensitive industries. By verifying results and ensuring proper protocols, MROs contribute to a safer working environment and mitigate legal risks for employers.
MRO Qualifications and Standards
To serve as a Medical Review Officer, an individual must be a licensed physician, holding either a Doctor of Medicine (MD) or Doctor of Osteopathy (DO) degree. MROs are required to undergo specialized training covering various aspects of drug testing. This training includes knowledge of controlled substance abuse disorders, pharmacology, laboratory testing methodologies, and specimen validity.
Certification is obtained through recognized national organizations, such as the Medical Review Officer Certification Council (MROCC) or the American Association of Medical Review Officers (AAMRO). These certifications require passing a comprehensive examination and mandate ongoing continuing medical education to ensure MROs remain current with evolving scientific and regulatory standards.
