Rapid Antimicrobial Susceptibility Testing


Antimicrobial susceptibility testing (AST) results have a significant impact when managing patients with serious infections. Recent developments in identification tools can now identify microbes with unprecedented speed, but phenotypic susceptibility testing has lagged behind. New phenotypic AST systems are being introduced with the promise of improving current molecular tests by rapidly measuring inhibition of growth across panels of antibiotics. In this presentation, we will explore the technology, performance, and impact on patient care of these new, rapid AST methods.
