Exempt media are highly stable formulations that have demonstrated a historically low rate of manufacturing and shipping failures (typically less than 0.1%).

Chocolate Agar (when used for fastidious organisms like Haemophilus spp. if not fully validated by the vendor) Selective media for specific fastidious pathogens Core Quality Control Parameters Detailed in M22-A3

For non-exempt or user-prepared media, CLSI M22-A3 defines specific procedures to verify performance: clsi m22a3 pdf

Watch for a potential M22-A4 (or a companion document) addressing data integrity (21 CFR Part 11 compliance for chromatography data systems like CDS) and artificial intelligence in peak integration. Until then, M22-A3 remains the authoritative source.

Even for "exempt" media, laboratories still maintain specific duties under the standard. Hardy Diagnostics Visual Inspection Exempt media are highly stable formulations that have

In clinical microbiology, the accuracy of diagnostic results depends heavily on the quality of the culture media used to isolate and identify pathogens. Substandard or degraded media can lead to false-negative results, delayed diagnoses, and compromised patient care. To standardize quality assurance, the Clinical and Laboratory Standards Institute (CLSI) published the document, titled "Quality Control for Commercially Prepared Microbiological Culture Media."

Outlines specific maintenance protocols, storage conditions, and quality control organisms required to verify media performance.

Obtain and file the Quality Control Certificate from the manufacturer for every lot number received. Ensure the certificate explicitly states compliance with CLSI M22-A3 standards. Step 3: Perform Testing on Non-Exempt Media

The standard creates a shared-responsibility model to guarantee media integrity from production to inoculation. Manufacturer Obligations
