: Ensuring proper storage temperatures and monitoring expiration dates.
To streamline laboratory operations, M22A3 classifies microbiological media into distinct categories regarding quality control testing.
These are media that do not require routine end-user quality control testing. Their exemption is based on extensive quality control data collected from surveys of clinical laboratories enrolled in the bacteriology proficiency-testing program conducted by the College of American Pathologists (CAP).

The standard sets a clear cutoff for an acceptable failure rate at ≤0.5% , meaning no more than 5 out of 1000 units should demonstrate random defects.
: Accreditation bodies like the College of American Pathologists (CAP) and the Joint Commission require laboratories to align their Standard Operating Procedures (SOPs) with recognized standards like CLSI.
