BPIU
Breakpoints in Use (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.
