WHAT IS A MEDICAL REVIEW OFFICER ASSISTANT?
"The MRO may be assisted by one or more staff. An MRO assistant performs administrative functions and does not
perform any portion of the interview between the MRO and donor. The administrative functions typically include
receipt and sorting of test forms, presenting non-negative and fatally flawed files to the MRO for review, and
distribution of reports to clients.
Some MRO assistants also call donors, confirm their identity, and then transfer the calls to the MRO. Some MRO
assistants are also involved in the corroboration of medical explanations that donors may present to the MRO. An MRO
assistant should be detail oriented, well organized, and reliable.
Under the U.S. Department of Transportation (DOT) drug and alcohol testing procedures, the MRO must supervise the
MRO assistant. This supervision must include personal oversight of that assistant's work; personal involvement in
evaluating, hiring, and firing the assistant, line authority over the assistant for decisions, direction, and control; and
regular contact and oversight concerning drug testing program matters. The MRO's supervision and control cannot be
superseded by or delegated to anyone else with respect to test result review and other functions performed by the
