The Clinical and Laboratory Standards Institute (CLSI) Subcommittee on Antimicrobial Susceptibility Testing had its series of meetings to update breakpoints for a variety of classes of antimicrobials.

This year's Clinical and Laboratory Standards Institute (CLSI) Subcommittee on Antimicrobial Susceptibility Testing provided updated breakpoints on therapies.

The Clinical and Laboratory Standards Institute Subcommittee on Antimicrobial Susceptibility Testing held a virtual winter meeting and a hybrid summer meeting in 2022. Ad hoc working groups have several breakpoint revisions underway for multiple organism-drug combinations.

Updates include novel and revised breakpoints for azithromycin, polymyxins, daptomycin, and cefiderocol.
