ID Screen® Influenza A Nucleoprotein Indirect

The only commercial indirect ELISA for the specific detection of nucleoprotein antibodies in serum or egg yolk from chickens or turkeys.

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 available for use with layers. Egg yolk collection is easy for the veterinarian, and does not generate stress for the animal.
