From the Research

Yes, a Medical Review Officer (MRO) can provide consultation assistance to employers in all aspects of drug testing, though their primary role is to review and interpret drug test results. MROs are licensed physicians with specialized training in substance abuse and drug testing regulations who can advise employers on establishing comprehensive drug testing programs, including policy development, testing methodologies, specimen collection procedures, and regulatory compliance with DOT, federal, and state guidelines 1. They can help employers understand which drugs to test for, appropriate cutoff levels, and testing frequencies based on industry requirements. MROs can also assist with handling special situations like prescription medication use that might affect test results, reasonable suspicion testing protocols, and post-accident testing procedures. Their medical expertise allows them to provide guidance on the limitations of different testing methods and how to interpret various results. However, while MROs offer valuable consultation, employers should also consult with legal counsel for specific legal requirements in their jurisdiction, as drug testing laws vary significantly by location.

Some key aspects of drug testing that an MRO can assist with include:

  • Developing policies and procedures for drug testing, including specimen collection and chain of custody protocols
  • Interpreting test results and providing medical expertise to help employers understand the implications of positive test results
  • Assisting with reasonable suspicion testing and post-accident testing protocols
  • Providing guidance on the use of alternative specimens, such as hair or oral fluid, for drug testing
  • Helping employers navigate the complexities of drug testing regulations, including DOT and federal guidelines

It's worth noting that while MROs can provide valuable consultation, employers should also consider other factors when developing their drug testing programs, such as the potential impact on employee morale and the need for employee education and support programs. As noted in a recent study, a comprehensive approach to workplace drug testing that includes employee education and support can be an effective way to reduce the risks associated with drug use in the workplace 2. Additionally, employers should be aware of the evolving legal landscape surrounding drug testing and marijuana use, and should consult with legal counsel to ensure that their policies and procedures are compliant with relevant laws and regulations 3.
