Strain Reactivity with Influenza A and B Viruses
The BD Veritor System for Rapid Detection of Flu A+B test was evaluated using a panel of influenza strains. Each strain was
diluted and tested in triplicate until a point where not all of the replicates were positive. The dilution prior to that is provided in
the table below as a minimal detected concentration. All influenza A strains showed positive Flu A test results and negative
Flu B test results. Conversely, all of the influenza B strains showed positive Flu B test results and negative Flu A test results.
Although this test has been shown to detect novel avian influenza A (H7N9) and H3N2v cultured viruses the performance
characteristics of this device with clinical specimens that are positive for novel avian influenza A (H7N9) and H3N2v influenza
viruses has not been established. The BD Veritor System Flu A+B assay can distinguish between influenza A and B viruses,
but it cannot differentiate influenza A subtypes.
