The Challenge

iFAST is a medical diagnostics company tackling one of healthcare's most urgent problems: antibiotic resistance. Traditional susceptibility testing takes over 48 hours, slowing treatment decisions and allowing resistant strains to spread.

Their breakthrough technology cuts that to just 3 hours. But to unlock its full potential, iFAST needed an interface that lab professionals could use safely and confidently under pressure.

We designed the interface that brings iFAST's diagnostic breakthrough to life in the lab.

Outcomes

A guided step-by-step workflow leads users through complex preparation tasks with clarity, reducing human error and improving consistency.

A clean dashboard gives real-time visibility into sample incubation. Results surface in EUCAST-compliant format, ready to export to LIMS systems, fitting into existing lab environments with minimal onboarding.
