This role is essential to ensure fairness in the testing process and to protect the rights of the individuals being tested. The MRO also provides guidance on the potential for substance abuse issues and can recommend appropriate actions based on the test results. Their expertise helps maintain both workplace safety and employee rights, emphasizing the importance of having a qualified medical professional oversee this aspect of substance testing.
