Drug Screening MRO (Medical Review Officer)

"MRO" is the designation of an individual who has a vital role in the overall workplace drug testing process. "MRO" refers to a "Medical Review Officer" who in all cases must be a "MD" (medical doctor). The MRO helps protect both the rights of the employee being tested and the employer requiring the workplace drug testing.

MRO "reviews" include the interpretation of urinalysis test results reported by the workplace drug testing lab to ensure a scientifically valid result. Especially, the MRO attempts to determine whether a legitimate medical explanation could account for any "confirmed positive" result reported by the laboratory. This duty is fulfilled through telephone or in-person interview with the specimen donor and by giving the donor an opportunity - through their doctor or pharmacist - to provide evidence of legally-prescribed drug-use that may have caused the lab-positive.

When the MRO can determine that a legitimate medical explanation exists, the MRO will then "overturn" the results reported by the lab and, instead, report the "final" result to the donor's employer as "negative". While a small percentage of companies will not pay the extra expense associated with MRO services for workplace drug testing, such services do greatly enhance the validity and reliability of the overall workplace drug testing process. They also help ensure fairness to the donor and offer more protection to the employer in any case of later litigation due to a "positive" drug test where the employee has been suspended or fired.
