Gradient diffusion assays Etest and MIC Test Strip for itraconazole, posaconazole and voriconazole as well as isavuconazole (MIC Test Strip) were evaluated for Aspergillus fumigatus against EUCAST broth microdilution. Both assays demonstrated generally good performance; however, posaconazole MIC Test Strip showed low agreement with broth microdilution due to MIC overestimation.
