QuickMIC's gradient technology vs broth microdilution

Improve clinical decisions

Our unique technology utilizes a continuous linear antibiotic gradient which allows for higher resolution, precision and accuracy than methods based on discrete concentrations.

  • Confident MIC reporting
  • High sensitivity around clinical breakpoints (SIR)
  • Better clinical outcomes and optimized dosing

Speed up lab workflow

QuickMIC performs AST directly from blood cultures and delivers results in 2-4 hours. Run QuickMIC in parallel with your rapid ID method of choice and report results to the clinical team even faster.

  • Same work shift actionable results
  • No plate culturing, no McFarland
  • Minimum hands-on time

Determine functional resistance in real time

Bacterial microcolonies exposed to a linear antibiotic gradient are followed in real time by live imaging. The software analyses the growth patterns of each microcolony along the linear antibiotic gradient to determine precise MIC values.

  • Results can be visually monitored throughout the run for each antibiotic
  • Phenotypic detection of antibiotic resistance
