Influenza A

ID Screen® Influenza A Antibody Competition Multi-species


Competitive ELISA kit for the detection of antibodies against the nucleoprotein of the Influenza A virus in multiple species

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.






  • Accurate and reliable results
    • Highly sensitive and specific
    • Positive and negative reference sera available as internal controls
  • Improved workflow
    • Easy-to-use, with results in under 2 hours
    • Comprehensive data analysis with the ID Soft™program
  • Flexible
    • Convenient multi-species test applicable to birds, horses, swine. Consult us for use in any other species.
    • For avian species:
      • use with egg yolk samples which are easier to collect and cause less stress to the layers
      • use with Serum Transport Cards, allowing for practical and safe shipment of blood or serum samples to the lab
