A Medical Review Officer (MRO) is a licensed physician who is responsible for recieving and reviewing laboratory drug test results generated by an employers drug testing program and evaluating medical explanations for confirmed positive, adulterated, substitued, and invalid test results.   They are an independent and impartial advocate for the integrity of the drug test process.

MRO's are trained and certified to review drug test results by the Medical Review Officer Certification Council (MROCC) or the American Association of Medical Review Officers (AAMRO).   MRO's must recieve continuing education in drug and alchohol testing and undergo re-certification to maintain their MRO certification.   

Although we offer (and recommend) MRO services for both federal and non-federal test results, review of federal (DOT programs) results is required by law.   Further, some states require MRO for non-federal results.  Please contact us for information about your State Laws.

Medical Review Reporting Procedures:

  • The MRO and/or MRO staff contacts the donor within 24 hours of the questionable result to verify any medical explanation. If the MRO is unable to contact the donor within a reasonable time period at the home phone number provided, we will contact the employer for assistance.
  • Daily calls are made until verification is complete.
  • If there is a medical explanation, the donor is required to provide to the MRO and/or the MRO staff in writing, from his physician or pharmacy, his medical explanation within five days. If no medical explanation is provided, the MRO and/or MRO staff verifies receipt of the Chain of Custody copies 1 and 2 for accuracy and reports the result as a verified positive to the employer.
  • DOT requires a 10 day no-contact time frame before verifying a positive result to the employer.  However, if the employer  has documented that the donor has been given contact information for the MRO and has failed to comply with the request of the employer  to contact the MRO within 72 hours, at that time, the MRO can report the result as a “No-Contact” positive to the employer.
