EQA medical biology

Description of the programme

These interlaboratory comparisons (AGLAE's programme ‘118A’) address any laboratory carrying out microbiological analyses (medical biology laboratories, hospital laboratories, testing laboratories...).

Characteristics of these EQA:

  • Receipt of a neutral solution contaminated by an identified strain, with a clinical scenario
  • Isolation, preparation of the inoculum and implementation of an Antimicrobial Susceptibility Testing (AST) by application of MIC strips
  • On-line data entry
