EPIDEMIOLOGICAL CUTOFF VALUES • A value used to assist with interpretation of MIC data where sufficient clinical data is not available for the purpose of establishing clinical breakpoints • Chosen by taking into account the MIC distribution of a species, the modal distribution, and the inherent variability in MIC testing methods (typically 2 dilutions above the modal MIC)
EPIDEMIOLOGICAL CUTOFF VALUES • Although the exact percent varies per publication, most agree that the wild-type strains should comprise 95-99% of any test set • Ideally, test sets contain in excess of 1000 strains • Strains with MICs above the ECV are considered to have potentially acquired mechanisms of resistance
