Abstract
Provided are systems, devices, kits, and methods that are used for antimicrobial sensitivity testing (AST). The systems, devices, kits, and methods provide a capillary-based antimicrobial susceptibility testing platform referred to as “cAST” that provides faster determination of antimicrobial susceptibility using lower sample volumes than previous approaches. The cAST approach includes performing AST by measuring colorimetric or fluorescent signal changes in samples in conduits that contain antimicrobial agents and one or more dyes. The conduits are operably linked to a light source and a light detecting component through a mount configured to hold the conduits and thereby determine changes in light that indicates changes in bacteria growth in the present of the antimicrobial agents.
