Clinical breakpoints

Clinical breakpoints are for everyday use in the clinical laboratory to advise on patient therapy.
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.
