EUCAST organises microbiology and infectious diseases in Europe and in many other countries.

  • To determine and review breakpoints
  • Develop methodology for AST
  • Develop criteria for QC
  • Education and training
  • To advertise ECDC and other European Union health agencies on issues related to antimicrobial susceptibility testing and detection of resistance determinants relevant to public health
  • To collaborate with international groups
  • To work towards international consensus and harmonisation of clinical breakpoints and antimicrobial susceptibility testing

The map displaying current uptake of EUCAST guidelines is shown here or in the See also links below. They also have a useful newsletter detailing the latest updates.

Other organisations include the FDA and CLSI over in the USA.

UK NEQUA organise external quality control for the UK but others can apply.

Finally, all countries are encouraged to form a NAC (National AST Committee) which helps laboratories implement good laboratory practices in the field of susceptibility testing. Find the chair persons of NACs by clicking here.
