Clinical breakpoints and dosing of antibiotics

What to do when there are no breakpoints in the EUCAST table?

Sometimes breakpoints for a species and/or an agent are lacking in EUCAST tables.

It may be because we have not yet had time to evaluate the agent or the species. The guidance document "When there are no breakpoints" suggests several alternative actions, including using the PK-PD breakpoints or MIC distributions.  

Do not use breakpoints from other breakpoint setting organisations unless these have been reviewed in modern times.
