Verify that no media is used past its stated expiration date.

It ensures that commercially prepared media meet stringent quality requirements.

, establishes guidelines for the QC of culture media, distinguishing between exempt and non-exempt media to optimize laboratory testing efficiency. It outlines mandatory procedures for testing sterility, growth performance, and selectivity, which are crucial for regulatory compliance and accreditation.

: Maintaining strains in a way that prevents genetic drift or loss of viability.

The CLSI M22-A3 standard outlines quality control requirements for commercially prepared microbiological culture media, reducing the need for user testing on "proven reliability" media while establishing an acceptable failure rate of ≤0.5%. While applicable internationally, US laboratories now primarily follow Individualized Quality Control Plans (IQCP) under CLIA regulations rather than strictly adhering to M22-A3, which was updated to include 27 additional exempt media types.

Below is an in-depth look at what the M22A3 standard entails, its key components, and why it remains a fundamental document in clinical microbiology. The Purpose and Scope of M22A3

for obvious defects (e.g., contamination, cracking, moisture loss). Document the receipt and inspection of the media. M22-A3 remains a global gold standard.

The Clinical and Laboratory Standards Institute (CLSI) document is the definitive global standard for the quality control (QC) of commercially prepared microbiological culture media. For laboratory managers, QA specialists, and medical technologists, understanding this document is critical to ensuring patient safety, regulatory compliance, and diagnostic accuracy. 1. What is CLSI M22-A3?

: This is the primary source. The document is available as an electronic PDF download for approximately $180.00 (discounted for members).

While US laboratories under CLIA regulations have transitioned toward as of 2016, M22-A3 remains a global gold standard. It is frequently used as the scientific evidence base for risk assessments when building an IQCP.
