ID Screen® Influenza A Nucleoprotein Indirect

The only commercial indirect ELISA for the specific detection of anti-nucleoprotein (NP) antibodies in serum or egg yolk from chickens, turkeys, ducks and geese.

  • Designed to monitor all AI killed vaccines (H5, H7, H9…) in chickens, turkeys, ducks and geese.
  • May also be used as a DIVA* test, in combination with the ID Screen® Influenza H5 Indirect ELISA to detect natural infection in animals vaccinated with recombinant vaccines alone (rHVT-H5, RNAm-H5 types).
  • Also suited to monitor disease in SPF animals (in the same way as the ID Screen® Influenza A Antibody Competition Multi-species), thanks to its excellent sensitivity and specificity
  • Excellent correlation with HI test
  • Quantitative – results may be expressed as titres
  • Comprehensive data analysis with the IDSoft™ program
  • Chloroform-free egg yolk protocol available for use with layers. Egg yolk collection is easy for the veterinarian, and does not generate stress for the animal.
