## Abstract

The Food and Drug Administration (FDA, the Agency, or we) is issuing a final rule to revoke the methods of analysis regulation, which describes an FDA policy to use certain methods of analysis for FDA enforcement programs when the method of analysis is not prescribed in a regulation. FDA is issuing this action because the existing regulation is no longer necessary.
