Patent ID: 8007999

Claim:
A method of detecting an influenza viral particle in a bodily fluid from a subject, comprising: a) allowing a sample of said bodily fluid suspected to contain said influenza viral particle to react with a first immunoassay reagent and a second immunoassay reagent, both of which being contained within an immunoassay assembly of a cartridge, wherein said first immunoassay reagent binds to a hemagglutinin molecule to form a first immune complex on said influenza viral particle, and wherein said second immunoassay reagent binds to a neuraminidase molecule to form a second immune complex on said influenza viral particle, said immune complexes yielding one or more detectable signals that indicate the simultaneous presence of hemagglutinin and neuraminidase on said influenza viral particle wherein either the first or second immunoassay reagent is immobilized on a solid support; and b) detecting said one or more detectable signals generated from said immune complexes, wherein said simultaneous presence of hemagglutinin and neuraminidase is indicative of the presence of said influenza viral particle.
