The M22-A3 document strictly delineates the responsibilities of different parties to ensure the quality chain remains unbroken:

are often "exempt" from routine user re-testing, provided the user performs a visual inspection for defects. Visual Inspection Criteria: Users must check for physical imperfections, including: Cracked petri dishes or agar. Unequal filling or insufficient agar depth ( Excessive bubbles, rough surfaces, or contamination. Hemolysis of blood-containing media. Significant color changes or precipitates. Failure Thresholds:

The M22-A3 standard identifies specific media types that are considered "exempt" from routine, daily retesting by the end-user, provided the manufacturer’s QC is documented. Examples include: Standard blood agar plates. Common nutrient agars. Certain types of broth media.

Before any biological testing occurs, the standard mandates visual inspection protocols for every shipment received. Laboratories must check for: Correct labeling and expiration dates.

Microbiological culture media must support the growth of target microorganisms while inhibiting commensal flora. If a batch of media is defective, it can lead to false-negative results, delayed diagnoses, or incorrect treatment plans for patients. CLSI M22-A3 standardizes how these media are evaluated before they are used on patient samples. Core Objectives of the Standard

Often, accreditation bodies provide access to necessary standards as part of their compliance packages.

CLSI M22A3 is a guideline document that provides standards for antimicrobial disk susceptibility testing, which is a critical component of clinical microbiology laboratory testing. The document outlines the procedures for performing disk diffusion tests to determine the susceptibility of bacteria to antimicrobial agents. The guidelines cover various aspects of testing, including disk preparation, inoculum preparation, incubation conditions, and interpretation of results.

In clinical microbiology, the accuracy of a patient's diagnosis depends entirely on the quality of the agar plates and broths used to grow bacteria or fungi. If a batch of culture media is defective, it can lead to false-negative results, delayed treatments, or misdiagnoses. The CLSI M22-A3 standard establishes:
