The BD MAX MRSA Assay, catalogue #442953. An automated qualitative in vitro diagnostic test for the direct detection of Methicillin-resistant Staphylococcus aureus (MRSA) DNA from nasal swabs in patie.

The performance of the assay no longer conforms to this statement in the Analytical Specificity section of the Package Insert: One hundred-eleven (111) out of 111 MSSA strains tested at extremely high concentrations (> 106 CFU/swab), produced negative results with the BD MAX MRSA Assay. One of the samples tested with each of the CAP surveys MRS5-A 2014 and MRS5-B 2014 yielded false positive results.
