Third-Party Administrators (TPA) manage all, or part, of an employer’s DOT drug and alcohol testing program, sometimes including maintaining required testing records. They perform tasks as agreed to by the employer to assist in implementing the drug and alcohol testing program and to help keep the employer compliant with the DOT/FMCSA Drug and Alcohol Testing rules and regulations.

A consortium will often manage the DOT random testing programs of several employers, including those of owner-operators who are not permitted to manage random testing themselves. Consortiums that manage owner-operator programs play a very unique service agent role.

Medical Review Officers (MRO) are licensed physicians who have been trained and certified to review the lab results and to validate whether a test is positive. MROs receive laboratory confirmed urine drug test results; determine whether there is a legitimate medical explanation for a laboratory confirmed positive, adulterated, or substituted result; and review and report a verified result to the designated employer representative (DER) in a timely and confidential manner.
