CLSI M22-A3 serves as a foundational guideline for manufacturers and clinical laboratories regarding the quality control (QC) of antimicrobial susceptibility testing (AST) materials. Specifically, it addresses the evaluation and verification of commercial control materials used to monitor the performance of AST methods (such as disk diffusion and MIC testing). While the document provided essential protocols for QC verification, users must note that this standard has been retired and its contents redistributed into broader CLSI standards.

If you have been searching for the , you are likely looking for the official guidelines to validate your Liquid Chromatography (LC) systems. This article provides a deep dive into what M22-A3 is, why it matters, how to interpret its core requirements, and how to ensure you are using the correct version of this critical document.

is the globally recognized standard for performing quality control (QC) on commercially prepared and user-prepared microbiological culture media . Published by the Clinical and Laboratory Standards Institute (CLSI), this document ensures that the media used in clinical laboratories can reliably support the growth of pathogens while inhibiting non-pathogenic organisms.
