Utilize the PDF's text-search functionalities to rapidly build customized QC spreadsheets, reducing data-entry errors when transcribing ATCC strain numbers. Conclusion

Perform comprehensive QC testing on every batch/lot of media.

CLSI M22-A3, "Quality Control for Commercially Prepared Microbiological Culture Media," establishes protocols for testing ready-to-use media, emphasizing an acceptable failure rate of ≤0.5% for exempt media. While it defines responsibilities for QC, U.S. laboratories have transitioned from these exemptions to Individualized Quality Control Plans (IQCP). Purchase the document through the CLSI Shop .

Based on the CLSI M22-A3 table of contents , the document is organized into several key sections:

By understanding and adhering to the protocols laid out in the CLSI M22-A3 document, microbiology laboratories ensure high-quality diagnostic workflows, leading to accurate patient results and optimal healthcare outcomes.

Campylobacter agar, selective media for Neisseria gonorrhoeae (e.g., Thayer-Martin agar), and various specialized broth formulations. Key Maintenance and Storage Requirements clsi m22a3 pdf

Understanding CLSI M22-A3: The Standard for Quality Control of Microbiological Culture Media

(e.g., no more than 5 out of 1000 units with random defects).

A central concept of CLSI M22-A3 is the division of quality control obligations. While it defines responsibilities for QC, U

The CLSI M22-A3 document covers various aspects of blood culture collection, including:

In the United States, regulatory bodies like the under the CLIA (Clinical Laboratory Improvement Amendments) regulations, as well as accrediting organizations like the College of American Pathologists (CAP) and the Joint Commission , recognize CLSI guidelines.

By adhering to CLSI M22-A3, you aren’t just checking a box for accreditation. You are ensuring that every chromatogram, every peak, and every patient result meets the highest standard of clinical reliability.

Ensuring non-target organisms are completely or partially inhibited.

Saves thousands of dollars annually by reducing the need for redundant ATCC organism testing on exempt media. Based on the CLSI M22-A3 table of contents

Adhering to CLSI M22-A3 is not just a best practice; it is frequently a requirement for laboratory accreditation. Organizations such as the College of American Pathologists (CAP) and the Joint Commission align their inspection checklists with CLSI guidelines. Following this standard ensures your laboratory remains fully compliant during audits.

The CLSI M22A3 PDF document offers several key features and benefits, including:

: As of 2016, US labs subject to CLIA regulations must either follow the standard's full retesting requirements for all media or develop an Individualized Quality Control Plan (IQCP) to maintain exemptions. Clinical & Laboratory Standards Institute | CLSI

Exempt media are those that have demonstrated an extremely low historical failure rate (typically less than 0.1%). Under CLSI M22-A3 guidelines, if a laboratory purchases these media from a manufacturer that certifies compliance with M22-A3 standards, the end-user laboratory (inhibition and growth testing) on every lot. Common examples of exempt media include: Sheep Blood Agar (SBA) MacConkey Agar (MAC)
