scope:

Clinical and Laboratory Standards Institute document M61-Performance Standards for Antifungal Susceptibility Testing of Filamentous Fungi includes minimal inhibitory concentration and quality control tables developed following the guidance in CLSI documents M38¹ and M51.² The data in the tables are valid only when the methodologies in CLSI documents M38¹ and M51² are followed. Users should replace previously published tables with these new tables. Changes in the tables since the previous edition appear in boldface type.

The Clinical and Laboratory Standards Institute consensus process, which is the mechanism for moving a document through two or more levels of review by the health care community, is an ongoing process. Users should expect revised editions of any given document. Because rapid changes in technology may affect the procedures, methods, and protocols in a standard or guideline, users should replace outdated editions with the current editions of CLSI documents.
