Clinical and laboratory impact
The Clinical and Laboratory Standards Institute (CLSI) M22-A3 document, titled Quality Control for Commercially Prepared Microbiological Culture Media, represents a pivotal shift in laboratory regulatory standards and operational efficiency. Published as the third edition of this approved guideline, M22-A3 provides a scientifically grounded framework for the quality assurance of culture media, moving away from redundant testing toward a system based on manufacturer performance and risk assessment. For clinical laboratories, understanding and implementing the principles within the M22-A3 guideline is essential for maintaining compliance while optimizing resource allocation. clsi m22a3 pdf link
