The primary objective of this study is to compare the performance of the investigational fluID Rapid Influenza Test and the BinaxNOW® Influenza A & B Test in detecting influenza type A and influenza type B, with respect to fresh nasal wash / aspirate specimens collected from patients presenting with signs and symptoms of influenza-like illness (ILI). Specimens to be evaluated in this study will be enrolled in a concurrent clinical study per protocol FLU-05, entitled "Prospective Evaluation of the fluID Rapid Influenza Test". All subjects enrolled in the FLU-05 study will have consented to having their samples used in future investigations involving the fluID Test.
