Frequently Asked Questions (FAQ)

Frequently Asked Questions (FAQ)

The EUCAST secretariat receives many questions on subjects ranging from how we determine breakpoints, how to use the MIC-distribution website, how ECOFFs are determined, disk diffusion methodolog etc. We try to answer each question individually but also publish frequently asked questions and answers in a classical FAQ document.

The file is updated at regular intervals.
