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:

Non-Exempt media includes complex, selective, or highly sensitive formulations that are prone to deterioration during shipping or storage. Laboratories must perform full, independent quality control testing on every new lot of non-exempt media before using it for patient diagnostics. Examples of non-exempt media include: Campylobacter media (e.g., Campy-CVA)
