EUCAST has evaluated (August 2022) commercially available tests and all have problems with accuracy, reproducibility, bias and/or for some, with skipped wells. For this reason, it is difficult to resolve the susceptibility interpretation of isolates in the ATU (area of technical uncertainty) in…

Get to know moreMethodology and Instructions Although the general principles for the development of breakpoints are similar to those for bacteria, susceptibility testing of fungi needs special attention. This page lists the documents that address the methods needed for testing of different fungi. AST of Yeasts…
Get to know moreECOFFinder. The previously available ECOFFinder software is no longer accessible on the EUCAST website because, according to EUCAST procedures ( SOP 10.2), setting ECOFFs or TECOFFs on single or already aggregated distributions is not acceptable according to EUCAST recommendations. Software and…
Get to know moreRapid AST in blood culture For selection of an efficacious antibiotic therapy rapid susceptibility results are desirable, but the usual overnight incubation precludes rapid results. EUCAST RAST fills this gap by providing results within 4 to 8 hours of incubation. The method is validated for…
