Abstract

A method for determining the antimicrobial susceptibility of a microorganism in a clinical sample includes removing a test aliquot from a clinical sample culture before the culture reaches 0.5 McFarland units and isolating the microbial cells. The cells are transferred into a suitable culture medium for microbial growth and an AST assay is performed using the isolated microbes. The concentration of microbial cells in the microbial cells used to set up the AST assay is measured before measuring the degree of microbial growth in different conditions of the AST assay. Devices for determining the anti-microbial susceptibility of a microorganism in a clinical sample are also disclosed.
