AST should be done on clinically significant isolates only.The decision as to what defines clinical significant may require consultation between microbiology staff,medical director,supervisor,infectious disease specialist,and attending physician in charge of the patient's care.Also,for isolates that are significant but there are not standardized methods for testing,either information from the literature should be used to guide treatment or testing can be done with a disclaimer that results must be viewed with caution.
