Responsible for testing raw materials, maintaining the manufacturing process, and providing documentation (e.g., Certificate of Analysis) for the performance of their media.
Visit the CLSI website (clsi.org) and search for “M22-A3.” Prices typically range from $150–$300 depending on membership status. Institutional access may also be available.
The standard streamlines laboratory workflows by classifying culture media into distinct categories based on historical reliability.
An search for typically comes from laboratory professionals, microbiologists, or quality assurance managers looking for the Clinical and Laboratory Standards Institute (CLSI) guideline titled Quality Control for Commercially Prepared Microbiological Culture Media . clsi m22a3 pdf free
The standard incorporated findings from College of American Pathologists (CAP) surveys, leading to the exemption of 27 additional media types compared to its predecessor (M22-A2). Performance Criteria: It sets a maximum acceptable failure rate of is less than or equal to
It identifies specific culture media with high proven reliability. Laboratories using these "exempt" media are not required to perform routine quality control (QC) testing, provided the manufacturer is compliant with M22-A3 standards. Reduced QC Burden:
: Today, the industry has moved toward an Individualized Quality Control Plan (IQCP) . Organizations like the American Society for Microbiology (ASM) now provide templates that broaden these concepts, replacing the older M22-A3 standard with risk-based assessments that still ensure patient safety. How to Access CLSI M22-A3 Performance Criteria: It sets a maximum acceptable failure
The CLSI (Clinical and Laboratory Standards Institute) M22-A3 standard provides guidelines for the preparation of plates, media, and reagents used in microbiological testing.
The official title of the document is . It was published in June 2004 by the Clinical and Laboratory Standards Institute (CLSI), a globally recognized, not-for-profit organization that develops clinical laboratory standards through a rigorous consensus process.
The U.S. Food and Drug Administration (FDA) has recognized this approved-level consensus standard for use in satisfying regulatory requirements for medical devices, specifically in vitro diagnostics. The FDA recognized it on January 14, 2019, under recognition number 7-178, with the extent of recognition listed as "Complete". This recognition ties the standard to several device categories, including culture media for isolating pathogenic Neisseria, selective and differential media, general nutrient broths, and others, underscoring its regulatory importance. we recommend the following:
If you need the content for study or lab implementation, I’d be happy to summarize the key principles of M22-A3 (e.g., quality control testing frequencies, organism strains, acceptance criteria for sterility, growth promotion, and inhibition). Let me know how I can help further.
If you are currently evaluating your laboratory's compliance workflows, let me know if you need help finding the required for a particular type of media or if you want to know how the latest regulatory updates affect media exemption status. Share public link
