About CLSI


CLSI U Educational Webinars

Learn how to optimize practices and processes in your laboratory.

Webinars provide an efficient, cost-effective way to learn more about recently published CLSI documents, important industry topics, and critical government mandates.

Through these webinars, CLSI’s volunteers share their own expertise and insight on the subjects at hand while using Q&A sessions to encourage participant discussion and interaction.

Attendees can earn P.A.C.E.® continuing education (CE) credits without leaving the laboratory. CLSI often partners with organizations such as the Association of Public Health Laboratories (APHL) and The Joint Commission to provide additional perspectives on shared issues. This collaboration further enables the development of optimal practices and processes in the laboratory.

CLSI-SIDP Webinar: News You Can Use: 2016 CLSI Updates and Controversies in Gram-Negative Antimicrobial Stewardship

Thursday, October 13, 2016 | 3:00–4:00 PM Eastern (US) Time

Emily L. Heil, PharmD, BCPS-AQ ID
Assistant Professor – Infectious Diseases
Department of Pharmacy Practice and Science
University of Maryland School of Pharmacy
Baltimore, Maryland, USA

Barbara L. Zimmer, PhD

Antimicrobial resistant organisms – in particular gram-negative organisms – continue to plague the infectious diseases landscape. A number of susceptibility and interpretation criteria have recently been modified by the Clinical and Laboratory Standards Institute (CLSI) that directly pertain to the gram-negative organisms. This session will highlight diagnostic and treatment approaches to resistant gram-negative organisms, with special attention to carbapenem-resistant Enterobacteriaceae (CRE) and extended-spectrum beta-lactamases (ESBLs).


  • Discuss the 2016 CLSI standards for antimicrobial susceptibility testing
  • Review the commonly used microbiology testing methods utilized to detect carbapenem-resistant Enterobacteriaceae (CREs).
  • Identify treatment options for resistant gram-negative pathogens, with a focus on CRE/ESBLs.
  • Discuss how to incorporate microbiology results into an antimicrobial stewardship program.

This webinar is hosted by SIDP and all registration must be done through the ProCE website.

CAP/CLSI Webinar: Practical Recommendations for Antifungal Susceptibility Testing and Reporting in Clinical Laboratories: New Drugs, New Breakpoints, New Guidelines

November 15, 2016 | 1:00–2:00 PM Eastern (US) Time

Mariana Castanheira, PhD

With the increasing availability of a variety of antifungal agents, susceptibility testing of yeasts associated with significant infections is becoming increasingly important. Clinical laboratorians must know how to approach antifungal testing to help guide treatment decisions. This webinar will focus on the most current recommendations for antifungal testing and reporting to include those found in the newer CLSI documents M57 and M59. The use of epidemiological cutoff values (ECVs) to interpret results will be described in detail as will effective reporting of antifungal susceptibility test results to the health care team. Newer antifungal agents including isavuconazole will be described and strategies for when to test specific agents will be presented. Finally, speakers will address applications in the clinical laboratory for the new College of American Pathologists (CAP) checklist items related to antifungal susceptibility testing and reporting. This webinar is intended for laboratorians, pharmacists, and clinicians who perform antifungal testing and/or use results of antifungal testing for clinical decisions.


  • Communicate the difference between a clinical breakpoint and an ECV to the health care team.
  • Formulate approaches to susceptibility testing and reporting of newly approved and older antifungal agents.
  • Apply the recently published CAP antifungal checklist items to the clinical laboratory.
