About the Susceptibility Testing Subcommittees
Subcommittees are responsible for two or more related documents in a topic area. They write draft documents, evaluate and respond to comments on content throughout the document development process, conduct scheduled document reviews, and may be responsible for continual revision of certain documents.
CLSI has established subcommittees in the following areas:
Antimicrobial Susceptibility Testing (AST) Subcommittee
The AST Subcommittee provides useful information to laboratories, enabling them to advise clinicians in the selection of appropriate antimicrobial therapy.
Antifungal Susceptibility Testing Subcommittee
The Antifungal Subcommittee collaborates to develop standards and guidelines that promote accurate antifungal susceptibility testing and appropriate reporting.
Veterinary Antimicrobial Susceptibility Testing (VAST)
The VAST Subcommittee collaborates to develop standards and guidelines that promote accurate antimicrobial susceptibility testing and appropriate reporting.
