The BrCAST halo interpreter

Choose one of the 8 isolate groups — Enterobacterales, Pseudomonas aeruginosa, Acinetobacter, Staphylococcus, Enterococcus, Streptococcus A/B/C/G, S. pneumoniae or Haemophilus influenzae — fill in the disc batch used on the plate, and the site returns the category for each antimicrobial, the applied breakpoint, and the consolidated report ready for review.

By disc batch

Fill in the entire isolate panel at once, just like on the plate.

Criterion at a glance

Each result shows the applied cut-off, e.g.: S ≥ 22 mm · R < 16 mm.

Bench notes

Cefoxitin as MRSA marker, D-test, screenings and confirmation alerts.
