CLSI BPIU

The College of American Pathologists (CAP) is introducing two new requirements for clinical laboratories to use updated breakpoints (BPs) when interpreting antimicrobial susceptibility testing (AST) results. CAP has recognized that some laboratories are using obsolete breakpoints, even when devices have achieved US Food and Drug Administration (FDA) clearance for updates, which could lead to adverse consequences in managing patients. 

CLSI's Outreach Working Group has developed this free, optional spreadsheet that laboratories can use to record breakpoints in use.

Please note that CAP is not prescriptive on the method used to document BPs in use.
