Antibiograms are cumulative antimicrobial susceptibility test (AST) reports of bacterial isolates used to show current resistance and to compare resistance trends over time. They are useful in monitoring antimicrobial resistance in a population and help clinicians choose empiric therapy until an AST report for cultured bacterium is available from the laboratory. However, antibiograms do not represent isolates from all patient populations and may vary greatly by geographic region or species. Thus, antibiograms are intended for use in conjunction with traditional culture and susceptibility testing and samples still must be sent to the laboratory for testing. To obtain reliable results, samples always should be collected prior to administering antimicrobial therapy.
