The CLSI M22-A3 standard is crucial for modern microbiology laboratories, balancing the need for rigorous quality control with the reliability of commercial manufacturing. By following the M22-A3 guidelines, labs can optimize their QC efforts, focusing resources where they are needed most.
The standard provides practical guidance for quality control (QC) of commercially prepared culture media. The basic premise of M22‑A3 is that . The categorization of media that do not require user‑initiated retesting is based on QC data from a large number of clinical laboratories.
Furthermore, M22-A3 aligns with the , which applies a core set of "Quality System Essentials" (QSEs) to all operations in a healthcare service's path of workflow.
