KB Quick

Capture and measure Kirby-Bauer plates with the data needed for EUCAST, CLSI, or custom-breakpoint interpretation. Photo to shareable PDF in minutes — six languages.

KB Quick is a professional reference and workflow tool, available to any diagnostic laboratory professional, microbiologist, or veterinarian worldwide. It supports the Kirby-Bauer disk-diffusion method of antibiotic susceptibility testing. Accounts are free and open to anyone; no invitation, organizational affiliation, or pre-approval is required.

Go from a photo to an annotated, shareable plate report in minutes — entirely on-device.

KEY FEATURES

Smart Plate & Disk Detection Computer vision automatically locates the plate and every antibiotic disk in the captured image. Supports optional ArUco fiducial markers for precise scaling on irregular setups.

Manual Editing Reposition, add, or delete disks in a zoomed editor for full control over the final measurement set.

Guided Zone Measurement Drag-to-size each inhibition zone with sub-millimeter precision. Mark zones as "No Zone" with a single tap.

Standards-Aligned Data Capture Record precise zone measurements together with the antibiotic, organism, host-species, and clinical-indication details that susceptibility interpretation depends on — so your measurement record is complete and structured for whatever breakpoint standard your lab uses (EUCAST, CLSI, or custom).

Shareable PDF Report Generate a shareable A4 PDF of your annotated plate — every disk labeled with its measurement (or "No Zone" marker) and antibiotic code — alongside the case identifier. Designed to print cleanly on standard paper.

Six-Language UI English, Russian, Tajik, Spanish, Brazilian Portuguese, and Vietnamese, with in-app switching at any time.

On-Device & Offline Capture, detect, and measure with no internet connection required — the full capture-and-measurement workflow runs on your device. Share the resulting report by email, AirDrop, Messages, or print.
