The xTAG RVP was used to resolve discrepant Alere and Xpert results.
The test result is the type (influenza A or B) of influenza virus found if the test result was positive or negative on any of the 3 molecular assays. The number of samples with the indicated test result is shown in parentheses.
FP, false-positive; FN, false-negative.
