Accurate, reliable AST results across clinical, veterinary, and surveillance domains
Your choice ofAST plates or discswill depend on your preferred methodology (broth microdilution or disc diffusion), the level of automationandsize of your lab,as well as itsintended use requirements (IVD or RUO).You'll also need quality control (QC) strains and plate or disc testing accessories such as broths, media, reagents, and plastics.

AST discs
The disc diffusion method categorizes resistant, intermediate, and sensitive organisms through qualitative results. It also provides a visual indication of inoculum level, presence of contamination, resistant mutants, beta-lactamase activity, and antagonism and synergy between antibiotics.
