Section I-1509 - Reporting and Review of Results

1. Medical Review Officer-a licensed physician responsible for receiving laboratory results generated by employer or testing entities' drug testing program who has knowledge of substance abuse disorders and has appropriate medical training to interpret and evaluate an individual's positive test result together with his medical history and any other relevant biomedical information. The role of the MRO is to review and interpret positive test results obtained through the office's testing program. In the conduct of this responsibility, the MRO should undertake the examination of alternate medical explanations for a positive test result. This action could include conducting of employee medical interviews, review of employee medical history, or the review of any other relevant biomedical factors.

2. The MRO is required to review all medical records made available by the tested employee when a confirmed positive test could have resulted from legally prescribed medication. After the MRO has reviewed the pertinent information and the laboratory assessment is verified, the results are to be forwarded to the employer and the Office of Workers' Compensation. Should any question arise as to the veracity of a positive test result, the MRO is authorized to order a reanalysis of the original sample. If the MRO determines there is a legitimate medical explanation for the positive test result, MRO may deem that the result is consistent with legal drug use, and take no further action.
