Medical Review Officer (MRO):
According to DOT regulations, all DOT drug screens must be reviewed by an MRO. Many states also require an MRO review. An MRO is a license M.D. with a history of substance abuse diagnostic work. This service is also available for Non-DOT testing, if desired. During the MRO's review it may be necessary for them to contact and speak directly with the donor to verify any types of medication the donor has taken. The client will not be notified if this occurs and will only be notified when a test result is available.
