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
MethodCompetitive ELISA
SpeciesMultiple species, including horses, birds, swine and others
