CLSI Publishes New Guideline for Identification and Potential Elimination of Immunoassay Interference Caused by Antibodies
Wayne, Pennsylvania, USA—March 2008—Because of their sensitivity and specificity, immunoassays are important diagnostic tools allowing measurement of a wide variety of analytes. Immunoassays, however, are subject to a number of interferences, including those caused by circulating endogenous antibodies. These circulating endogenous antibodies can cause falsely increased or decreased results or may lead to misinterpretation of results.

Clinical and Laboratory Standards Institute (CLSI) has recently published a new document, Immunoassay Interference by Endogenous Antibodies; Approved Guideline (I/LA30-A), which presents information on the origin, nature, and prevalence of circulating endogenous antibodies that cause interference with immunoassay results. The guideline describes methods for identification and potential elimination of immunoassay interference caused by antibodies in patient specimens.

CLSI Publishes Standard for Antimicrobial Disk and Dilution Susceptibility Tests for Bacteria Isolated From Animals
Wayne, Pennsylvania, USA—March 2008—In order to have a positive impact on clinical outcomes, help maintain antimicrobial effectiveness, assist clinicians in using antimicrobials safely, and minimize selection of resistant pathogens, laboratories must use a standardized, well-defined method for performing antimicrobial susceptibility testing (AST).

In response to this need, Clinical and Laboratory Standards Institute (CLSI) recently published an updated document, Performance Standards for Antimicrobial Disk and Dilution Susceptibility Tests for Bacteria Isolated From Animals; Approved Standard—Third Edition (M31-A3), which is predicated on providing AST methods that give accurate, reproducible, clinically relevant results for veterinary pathogens.

CLSI Publishes Guideline for In Vitro Susceptibility Testing Criteria and Quality Control Parameters for Veterinary Antimicrobial Agents
Wayne, Pennsylvania, USA—March 2008— Clinical and Laboratory Standards Institute (CLSI) recently published an updated document, Development of In Vitro Susceptibility Testing Criteria and Quality Control Parameters for Veterinary Antimicrobial Agents; Approved Guideline—Third Edition (M37-A3), which offers guidance for developing agar disk diffusion zones of inhibition, dilution MIC breakpoints, and quality control limits for antimicrobial susceptibility testing of aerobic bacteria isolated from animals.
