For non-exempt media, laboratories must maintain a collection of American Type Culture Collection (ATCC) strains. The standard outlines: for antimicrobial susceptibility testing

The primary objective of the M22-A3 guideline is to define the responsibilities of both the manufacturer and the end-user laboratory regarding the quality control (QC) of microbiological media. Historically, laboratories were often required to perform extensive "in-house" testing on every batch of commercially prepared media to ensure sterility and growth support. However, M22-A3 identifies specific media with a high history of stability and consistent performance, classifying them as "exempt" from routine user QC testing, provided the manufacturer is compliant with stringent quality standards. This classification allows laboratories to trust the manufacturer’s Certificate of Analysis (CoA) for low-risk media, such as Blood Agar or MacConkey Agar, thereby reducing the consumption of reagents, personnel time, and financial resources.

for antimicrobial susceptibility testing, the fundamental principles of media quality control found in M22-A3 remain the backbone of reliable diagnostics. Following these standards helps prevent erroneous results that could negatively affect patient care. Are you updating your lab's Quality Control plan?
