• Not all isolates tested against every antibiotic listed

• CONS: coagulase negative staphylococci

• Vitek2 system includes an advanced expert system (AES) that analyzes MIC patterns and detects phenotypes for most organisms tested. The AES also deduces susceptibility to drugs not tested based on antimicrobial phenotype of the strain
