In the United States, laboratory compliance is governed by the Clinical Laboratory Improvement Amendments (CLIA). Major accreditation organizations, such as the College of American Pathologists (CAP) and the Joint Commission, utilize CLSI M22-A3 as the benchmark for evaluating a laboratory’s microbiology quality management system.
Providing the end-user with a Quality Control Certificate for every lot number. Laboratory (End-User) Responsibilities
The Clinical and Laboratory Standards Institute (CLSI) is a non-profit organization that develops standards through global consensus. Because generating these standards requires immense research and expert collaboration, CLSI operates on a paid-access model. clsi m22a3 pdf
Chocolate Agar (except when used for fastidious organisms like Neisseria or Haemophilus ) Eosin Methylene Blue (EMB) Agar 2. Non-Exempt Media (Requiring Full User QC)
The NFB-ID Resolver is a smart interpretation module integrated into a Laboratory Information System (LIS) or a standalone microbiology instrument interface. It digitizes the logic found in CLSI M22-A3 to address the most common problem in identifying Nonfermentative Gram-Negative Bacilli (NFB): conflicting or low-probability biocodes. In the United States, laboratory compliance is governed
