Are CLSI standards and guidelines mandatory?

CLSI develops and publishes standards and guidelines through a consensus process that involves representatives from government, industry, and the health care professions. Because of the unique credibility our threefold consensus process gives to our documents, regulatory agencies or accrediting bodies often require that a specific CLSI standard or guideline be followed. In these cases, following the standard or guideline becomes mandatory for institutions aiming to meet given regulatory or accreditation requirements.
