What Is a Medical Review Officer (MRO)?

Medical Review Officer (MRO) is a licensed physician specializing in interpreting and evaluating drug test results in the workplace. MROs play a critical role in the drug testing process for employers, particularly those in the transportation, healthcare, and manufacturing industries, where safety is a top priority.

MROs are responsible for verifying drug test results and determining whether an individual has a legitimate medical reason for a positive test result, such as a valid prescription for a medication that could cause a positive test. They also ensure the privacy and confidentiality of the drug test results and work closely with laboratories, employers, and employees to ensure compliance with applicable laws and regulations.

In addition to reviewing drug test results, MROs also serve as a resource for employers and employees on drug testing policies and procedures and drug and alcohol abuse prevention and treatment programs. Overall, the role of the MRO is to help maintain a safe and drug-free workplace by ensuring the accuracy and integrity of drug testing programs.
