These media have higher inherent failure rates, are highly complex to manufacture, or degrade easily during transport. Laboratories must perform full user quality control on every lot of non-exempt media before clinical use. Examples include Chocolate agar, Campylobacter agar, and selective media for fastidious organisms. 2. Responsibilities of the Manufacturer
This section covers the technical details of inoculating QC media, including direct inoculation, standardized suspension, and preparation of suspension.
Understanding CLSI M22-A3: The Standard for Quality Control of Microbiological Culture Media
Non-exempt media comprises formulations that are inherently unstable, highly selective, or prone to degradation during shipping and storage. Laboratories perform complete quality control testing on every lot number of non-exempt media received. Examples of non-exempt media include: Campylobacter Agar
The categorization is based on the of different media types—calculated as the proportion of lots failing quality control (QC) relative to the total number of lots tested. clsi m22a3 pdf
Given that M22-A3 no longer applies to CLIA-regulated US laboratories, what should laboratories use instead?
It ensures that every batch of media—whether agar plates, broths, or slants—supports the growth of target pathogens while inhibiting commensal flora as intended.
A critical part of the document, this section outlines the responsibilities of three key parties:
Here is a breakdown of legitimate and legitimate-but-wary options, and what to avoid. These media have higher inherent failure rates, are
CLSI M22-A3 is a document that outlines the performance standards for susceptibility testing of mycobacteria, nocardioform, and other actinomycetes. The guideline provides a framework for laboratories to perform accurate and reliable susceptibility testing, which is crucial for guiding patient care and antimicrobial therapy.
Selective media for Neisseria gonorrhoeae (e.g., Modified Thayer-Martin Agar) Certain specialized broths and anaerobic transport media Responsibilities Mandated by M22-A3
Adhering to the CLSI M22-A3 standard allows laboratories to satisfy CLIA '88 requirements for media quality control without wasting valuable reagents, tech time, and QC organisms on highly reliable, exempt media. However, surveyors and inspectors will audit the lab to ensure that:
: Covers requirements for sterility, physical appearance, and growth recovery. but a legitimate
