Antimicrobial Susceptibility Testing: 2023 Updates

Antimicrobial susceptibility testing (AST) to guide targeted antibiotic utilization is a critical function of clinical microbiology laboratories but the mechanisms of antimicrobial resistance can be confusing and the testing environment complex. In this series, experts in the field of AST will present the latest information on both introductory and advanced topics to give you the AST information you need to do your job, whether that be in a clinical or public health laboratory or as a practicing infectious disease physician.

Learning Objectives

  1. The attendee will be able to describe current best practice AST methods and limitations.
  2. The attendee will be able to describe the latest information on bacterial and viral resistance mechanisms.
  3. The attendee will be able to describe regulatory aspects of AST for clinical laboratories.
