Inspection bodies like the College of American Pathologists (CAP) and the Joint Commission evaluate laboratory QC protocols against CLSI standards. Having the exact text ensures your Standard Operating Procedures (SOPs) are fully compliant.

For , purchasing the PDF directly from the CLSI website is the most straightforward option.

Here is a breakdown of legitimate and legitimate-but-wary options, and what to avoid.

When testing is required, the standard outlines procedures for testing sterility, growth capacity, selectivity, and physical appearance.

Document that the media was stored at the manufacturer-specified temperatures continuously.

Through extensive multi-center studies, CLSI determined that certain types of commercially prepared media have exceptionally low failure rates (often less than 0.1%). Under M22-A3, if a laboratory purchases these media from a manufacturer that certifies compliance with CLSI standards, the laboratory is from performing full, routine microbial performance testing on those batches. Examples of typically exempt media include: Sheep Blood Agar (SBA) MacConkey Agar (MAC)

Compared to previous versions, this third edition introduced several refinements: Failure Rate Cutoff : Increased from Fastidious Organisms

The CLSI M22-A3 (3rd Edition) document, "Quality Control for Commercially Prepared Microbiological Culture Media," provides guidelines for the QC testing of microbiological culture media, focusing on reducing testing for low-failure "exempt" media. It classifies media into exempt and non-exempt categories, detailing specific QC parameters and the division of responsibility between manufacturers and clinical laboratories. The standard is a copyrighted publication of the Clinical and Laboratory Standards Institute (CLSI) and can be purchased on their official website or accessed through institutional subscriptions.

For non-exempt media (or for periodic checks), the laboratory must maintain a set of stable, pure-quality control organisms. The M22-A3 standard provides simplified protocols for maintaining these organisms, such as using standard methods like frozen stocks or lyophilized pellets.
