Breakpoints and Dosages

NordicAST breakpoint tables are based on EUCAST breakpoint tables, but have comments that are adapted to Nordic conditions. Starting with version 2.0 (January 2012), NordicAST tables are available in both Swedish and Norwegian. From version 9.0, the NordicAST table is also available in Finnish.

From v 10.0, the header of the worksheets (including method descriptions and columns with agents and breakpoints) are in English and common for the three versions of the table (Norwegian, Swedish, Finnish). General information, comments, figure text and flowcharts remain in the Nordic languages. From v 10.0 dosing tables are published seperately.

The tables are available in two versions: One for work on a computer screen (Excel) and one for printing (pdf).
