Note: Breakpoint data in this app is derived from CLSI M100 Ed. 36 (2026). Always verify against the current edition of the official standard before clinical use. This app does not replace the official CLSI publications.

This application was developed by William Xie, PhD, D(ABMM), a clinical microbiologist dedicated to translating complex clinical guidelines into practical digital tools. The goal is to make antimicrobial susceptibility reference information easier to access, faster to navigate, and more useful for clinicians and laboratory professionals in real-world diagnostic workflows.
