ID Screen® Influenza A Nucleoprotein Indirect

The only commercial indirect ELISA for the specific detection of nucleoprotein antibodies in chicken and turkey serum.

  • Designed to monitor killed vaccines in chickens and turkeys
  • May also be used as a DIVA* test, in combination with the ID Screen® Influenza H5 Antibody Competition ELISA to detect natural infection in animals vaccinated with rHVT-H5 vaccines alone
  • 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
  • Excellent correlation with HI test
  • Quantitative – results may be expressed as titres
  • Comprehensive data analysis with the IDSoft™ program
  • Chloroform-free egg yolk protocol coming soon for use with layers! Egg yolk collection is easy for the veterinarian, and does not generate stress for the animal.
