Other Microbiology Documents
CLSI has a longstanding globally trusted reputation for its diligent development of Microbiology and AST standards and guidelines on test methods and QC procedures. Additionally, CLSI annually creates and revises AST breakpoints to meet global public health challenges related to antimicrobial resistance. CLSI’s library of Microbiology standards and guidelines establish vital performance criteria and best practice guidelines for use in the clinical microbiology laboratory field.
It’s important for medical laboratories, drug and device manufacturers, and regulatory and accreditation organizations to understand how antimicrobial susceptibility testing (AST) breakpoints and interpretive categories are determined. CLSI has published rationale documents that provide the scientific reasons behind our AST Subcommittee’s decisions, along with documentation of the standardized data and methods used to determine breakpoints.
