The standard, titled "Quality Control for Commercially Prepared Microbiological Culture Media," provides essential guidelines for clinical laboratories regarding the testing of culture media [2, 5]. Developed by the Clinical and Laboratory Standards Institute (CLSI), this document establishes which types of media require rigorous user-performed quality control (QC) and which can rely on the manufacturer’s documentation [2].

Before this standard, laboratories were often required to test every single batch of every type of agar or broth they received. M22-A3 significantly reduced this burden by categorizing many common media (like Blood Agar or MacConkey Agar) as "exempt" from routine user QC, provided the manufacturer provides a certificate of compliance. This saves laboratories significant time and resources while maintaining patient safety. specific culture media Here are a few options: Before this standard,
