EUCAST MIC- and Zone diameter breakpoint tables

EUCAST MIC and Zone diameter breakpoint tables

In EUCAST tables, the I-category is not listed. It is implied as the values between the S-breakpoint and the R-breakpoint.
For a breakpoint listed as S<=1 mg/L and R>8 mg/L the intermediate category is 2 - 8 (technically >1 - 8) mg/L.
For a breakpoint listed as S>=22 mm and R<18 mm the intermediate category is 18-21 mm.

EUCAST breakpoint tables v 1.1 (April 27, 2010) - for screen

A new version (v1.1) of the breakpoint tables was released on April 27, 2010. All changes are listed separately on one of the first pages.

The zone diameter breakpoints are tentative during 2010. More data correlating MIC to zone diameter will be added and breakpoint correlates refined as needed. We invite you to participate in the validation of the breakpoints!
