RAST: Screening for resistance mechanisms of epidemiological and/or infection control importance

Screening for R-mechanisms with RAST

Some resistance mechanisms require other than clinical breakpoints for sensitive detection. 
EUCAST recommends screening for a number of resistance mechanisms for epidemiological and infection control purposes (see separate document). 


EUCAST has validated using separate screening cut-offs for the detection of E. coli and K. pneumoniae with ESBL or carbapenemases.
