Clsi M22a3 Pdf [upd] -
The CLSI M22-A3 (3rd Edition) document, "Quality Control for Commercially Prepared Microbiological Culture Media," provides guidelines for the QC testing of microbiological culture media, focusing on reducing testing for low-failure "exempt" media. It classifies media into exempt and non-exempt categories, detailing specific QC parameters and the division of responsibility between manufacturers and clinical laboratories. The standard is a copyrighted publication of the Clinical and Laboratory Standards Institute (CLSI) and can be purchased on their official website or accessed through institutional subscriptions.
- Special instructions for fastidious organisms (e.g., Haemophilus, Streptococcus spp.), anaerobes, or intrinsically resistant organisms.
- Guidance on testing for resistance mechanisms (e.g., inducible clindamycin resistance, ESBL screening, carbapenemase considerations) including follow-up confirmatory testing recommendations.
- The Function: A utility tool that helps the lab decide which platform to use for a specific isolate.
- Input: The lab technician inputs basic gram-stain and morphology data.
- Output: Based on M22-A3 tables, the wizard recommends the best commercial system available in the lab inventory for that specific NFB group to maximize identification accuracy.
Users: Focus on visual inspection and documentation of media upon receipt rather than full organism-based retesting for "exempt" media. clsi m22a3 pdf
