Posted in the Federal Register on Wednesday, October 3, 2012 is a Department of Transportation Final Rule:
Procedures for Transportation Workplace Drug and Alcohol Testing Programs:
6-Acetylmorphine (6-AM) Testing
This rule adopts as final, without change, a May 4, 2012, interim final rule (IFR) which no longer requires laboratories and Medical Review Officers to consult with one another regarding the testing for the presence of morphine when the laboratory confirms the presence of 6- acetylmorphine (6-AM). Also, laboratories and MROs will no longer need to report 6-AM results to the Office of Drug and Alcohol Policy and Compliance. The rule also responds to comments on the IFR.
