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

based on the standard's requirements — if you describe what type of report you need (e.g., media QC log, audit report, validation summary), I can create a structured outline.

This document is crucial for laboratory professionals, clinicians, and healthcare workers involved in the collection, transport, and processing of clinical specimens for microbiological culture.

CLSI M22-A3 outlines strict maintenance protocols that laboratories must follow to maintain the integrity of their media inventory: clsi m22a3 pdf

For professionals who need to ensure the performance, sterility, and reliability of their culture media—or for those involved in laboratory accreditation under ISO 17025—the official PDF of M22‑A3 is an indispensable resource.

Covers how to interpret the results of QC testing.

Exempt media are those that have demonstrated an extremely low historical failure rate (typically less than 0.1%). Under CLSI M22-A3 guidelines, if a laboratory purchases these media from a manufacturer that certifies compliance with M22-A3 standards, the end-user laboratory (inhibition and growth testing) on every lot. Common examples of exempt media include: Sheep Blood Agar (SBA) MacConkey Agar (MAC) These media have higher inherent failure rates, are
