By following these recommendations, we can ensure that antimicrobial susceptibility testing is performed accurately and reliably, and that patients receive effective treatment.

While M22-A3 (the third edition) is the current version, you might find summaries, referenced guidelines in published papers, or older public health documents (e.g., from WHO or CDC) that cover similar QC practices for culture media.

The standard emphasizes that even if a medium is exempt from user testing, laboratories must still monitor the product.

The M22-A3 standard identifies specific media types that are considered "exempt" from routine, daily retesting by the end-user, provided the manufacturer’s QC is documented. Examples include: Standard blood agar plates. Common nutrient agars. Certain types of broth media.

The search for a "clsi m22a3 pdf free" is common, as obtaining standards can be a significant expense, especially for small laboratories or individual professionals.

: This technical manual includes lists of "CLSI exempt" media sourced directly from the M22-A3 standard.

I understand you're looking for information about the document, which is titled “Quality Control for Commercially Prepared Microbiological Culture Media; Approved Standard—Third Edition.”

The standard's core principle is that the retesting of commercially prepared microbiological culture media is unnecessary for those media that have demonstrated proven reliability. The categorization of media that do not require retesting by the user is based on quality control data collected from surveys of clinical laboratories enrolled in the bacteriology proficiency-testing program conducted by the College of American Pathologists (CAP). These media types are well established for the recovery of clinically significant microorganisms. The standard applies to all commercial media listed in Table 2 of the document, regardless of packaging, plate, or tube design.

Laboratories use the M22-A3 document to streamline their quality control programs. Instead of testing every batch of media received, laboratories can use this document to justify limiting QC testing to high-risk or non-exempt media, which saves time and money.
