Final rule.

This rule adopts as final, without change, a May 4, 2012, interim final rule (IFR) which no longer requires laboratories and Medical Review Officers (MRO) 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 (ODAPC). This rule also responds to comments on the IFR.
