Positive drug test: A result that indicates that a specimen exceeded specified drug or metabolite cutoff levels. The result has undergone review and has been verified/confirmed by a medical review officer.his person reviews drug test results that are ânon-negative,â meaning results that are at or above the cutoff level and require additional review.
