All test results shall be submitted for medical review by the MRO. The Medical Review Officer will consider the medical history of the Employee or Applicant, as well as any other relevant biomedical information. When there is a confirmed positive test result, the Employee or Applicant will be given an opportunity to report to the MRO the use of any prescription or over-the-counter medication. If the MRO determines that there is a legitimate medical explanation for a confirmed positive test result, consistent with legal and non-abusive drug use, the MRO will certify that the test results do not meet the conditions for a determination of improper use of alcohol or illegal drugs. If no such certification can be made, the MRO will make a determination of improper use of alcohol or illegal drugs.History: Rule 07-98, eff. Feb. 9, 1999.
