Abstract：
:MALDI-ToF MS can be used to identify microorganisms directly from blood cultures. This study compared two methods of sample preparation. Similar levels of genus- (91% vs 90%) and species-level identifications (79% vs 74%) were obtained with differential centrifugation and SDS methods. The SDS method is faster and requires minimal handling.
