## Indications for use
mecA XpressFISH® is a qualitative nucleic acid fluorescence in situ hybridization assay intended for the detection of mecA mRNA on smears from blood cultures that are positive for Staphylococcus aureus by the Staphylococcus QuickFISH™ BC assay. The mecA XpressFISH® assay is indicated for use in conjunction with other laboratory tests and clinical data available to the clinician as an aid in the detection of mecA mRNA from methicillin-resistant S. aureus (MRSA) from patient positive blood cultures. The mecA XpressFISH® assay is not intended to monitor treatment for MRSA infections or for use with mixed cultures including those containing both S. aureus and coagulase negative staphylococci. Sub-culturing of positive blood cultures is necessary to recover organisms for susceptibility testing, epidemiological typing, and/or differentiation of mixed growth.
