MedDirect’s professional Medical Review Officers are licensed physicians knowledgeable in substance abuse disorders and have the appropriate medical training to interpret and evaluate an individual’s positive test result using verified medical information provided by the specimen donor.  MedDirect MRO’s Aaron White, M.D. and Lance Barton, M.D. are each credentialed in their medical discipline and certified by the American Association of Medical Review Officers (AAMRO).

The primary responsibility of the MRO is to review, evaluate, and interpret drug test results from the laboratory.  Positive test results must be carefully evaluated to determine any alternative medical explanation.  Proper research is conducted before producing conclusions.  We provide immediate MRO response on positive test results.

The MRO Assistant, Amanda Espy, having received her MRO training and education from the AAMRO works under the direct supervision of the MRO’s to facilitate the administrative process.

The MedDirect MRO Center strictly follows the guidelines established in Title 49 Part 40 “Procedures for Transportation Workplace Drug and Alcohol Testing Programs.”
