Understanding CLSI M22-A3: The Standard for Quality Control of Microbiological Culture Media
Direct access to the M22 Standard and updates.
The core premise of M22-A3 is that retesting commercially prepared media is often unnecessary if the media has a proven track record of high reliability. By analyzing failure rates from surveys conducted by the College of American Pathologists (CAP), the CLSI identified specific media types that consistently perform well. clsi m22a3 pdf
The M22 series has a rich history spanning over three decades, reflecting the evolution of laboratory quality control practices.
Adherence to CLSI M22-A3 is critical for laboratories seeking accreditation from major regulatory bodies such as the Clinical Laboratory Improvement Amendments (CLIA), the College of American Pathologists (CAP), and The Joint Commission.
If you are looking to obtain the official , it should be acquired directly from the official Clinical and Laboratory Standards Institute website or authorized medical publication distributors to ensure you have the legitimate, copyrighted, and unaltered document for your compliance library. The first step is to check the manufacturer’s
The document provides clear protocols for maintaining QC organisms, incubation conditions, and documenting media receipt. Key Sections of the M22-A3 Standard
During an audit, inspectors frequently ask to see the scientific rationale behind a laboratory's media exemption list. Referencing the specific tables within the M22-A3 PDF provides instant justification.
The laboratory must maintain documentation showing that the manufacturer is compliant with CLSI M22-A3 standards and has provided a Certificate of Quality Control for that specific lot. The core premise of M22-A3 is that retesting
The official M22-A3 PDF includes invaluable appendices (usually Appendix A, B, C) containing:
One of the most significant contributions of the CLSI M22-A3 document is the classification of commercially prepared media into two main categories: and Non-Exempt . This classification is based on extensive multi-center studies evaluating the historical failure rates of various media types. 1. Exempt Media (Low Failure Rate)
CLSI M22-A3 is the third edition of the globally recognized consensus standard that establishes quality control criteria for manufacturers and users of commercially prepared microbiological culture media.
