ID Screen® Influenza A Antibody Competition Multi-species

Competitive ELISA kit for the detection of anti-nucleoprotein (NP) antibodies.

Detects antibodies against all Influenza A subtypes and antigenic variants thanks to the use of a monoclonal antibody against a highly conserved epitope of the Influenza A virus nucleoprotein.


  • Highly sensitive and specific
  • Convenient multi-species test applicable to birds, horses, swine and others 
  • Easy-to-use, with results in under 2 hours
  • Comprehensive data analysis with the IDSoft™program
  • Positive and negative reference sera available as internal controls
  • For avian species: may be used with egg yolk samples which are easier to collect and cause less stress to the layers
Method Competitive ELISA
Species Multiple species, including horses, birds, swine and others
Specimens Serum, plasma or egg yolk
Coated antigen Influenza A nucleoprotein (NP)
Conjugate Anti-NP-HRP conjugate (concentrated 10X)
