Our procedures have been designed to ensure that consensus has been achieved when a standard or guideline is published at the approved level. This means that a document has been rigorously reviewed by the authoring subcommittee, the area committee overseeing the project, the Board of Directors, and the medical-testing community that participates in the consensus process by carefully reviewing and commenting on the standard or guideline.
