Please request pricing above to be notified of the release. The estimated publication date is Mid-March 2023, for the PDF version. Print copies will be available for shipping by end of March 2023.

The tables presented in M100 represent the most current information for antimicrobial susceptibility testing drug selection, interpretation, and quality control using the procedures in M02, M07, and M11.

This document includes updated tables for the Clinical and Laboratory Standards Institute antimicrobial susceptibility testing standards M02, M07, and M11.

Clinicians depend heavily on information from the microbiology laboratory for treating their seriously ill patients. The clinical importance of antimicrobial susceptibility test results demands that these tests be performed under optimal conditions and that laboratories have the capability to provide results for the newest antimicrobial agents. The tables presented in M100 represent the most current information for drug selection, interpretation, and quality control using the procedures standardized in CLSI's M02, M07, and M11. Over time, a microorganism’s susceptibility to an antimicrobial agent may decrease, resulting in a lack of clinical efficacy and/or safety. In addition, microbiological methods and QC parameters may be refined to ensure more accurate and better performance of susceptibility test methods. Because of these types of changes, CLSI continually monitors and updates information in its documents.
