title: Rapid Detection of Methicillin-Resistant Staphylococcus aureus and  Methicillin-Susceptible S. aureus Directly from Positive Blood  Cultures by Use of the BD Max StaphSR Assay.
abstract: The BD Max StaphSR assay is an automated qualitative in vitro diagnostic test for the direct detection and differentiation of methicillin-susceptible Staphylococcus aureus (MSSA) and methicillin-resistant S. aureus (MRSA). A total of 460 specimens were tested, and the results were compared with standard culture-based identification. MRSA was detected in 48 samples (sensitivity of 100%; positive predictive value [PPV] of 100%). MSSA was detected in 112 samples (sensitivity of 99.1%; PPV of 100%), and 299 samples containing coagulase-negative staphylococcus and nonstaphylococcal species were negative by the BD Max StaphSR assay (specificity of 100%; negative predictive value [NPV] of 99.7 to 100%).
