The SVANOVIR EHV1/EHV4-Ab is a indirect ELISA for detecting antibodies to Equine Herpesvirus (EHV) type 1 and type 4 in equine serum and plasma samples.

The test has been validated by the University of Kentucky and the University of Melbourne confirming its ability to contributing to effective and informed management of EHV positive horses during outbreaks, tournaments and race-meetings.


Features and benefits:

  • Highly accurate and valuable tool for detecting infection of EHV-1 in EHV-4 positive horses
  • The only serological test to differentiate between EHV-1 and EHV-4
  • Excellent for screening of maternal antibodies in foals in order to predict the best time for vaccination
  • Allows risk-classification of mares into EHV-1 exposed and susceptible groups
  • Developed in collaboration with the Centre for Equine Virology, University of Melbourne
  • Approved by the University of Kentucky as an easy-to-use tool offering good results rapidly


About Equine Herpesvirus 

The Equine Herpesviruses type 1 (EHV-1) and 4 (EHV-4) are ubiquitous pathogens that affect horse populations worldwide. Despite widespread vaccination, EHV-1 and EHV-4 infections remain a permanent risk. The two major types of equine herpesvirus have different clinical significance. EHV-1 infections can cause severe respiratory infection, abortions, neonatal foal death, and myeloencephalopathy. In contrast, EHV-4 primarily causes respiratory disease. Both types can cause a lifelong latent infection with recurrent reactivation leading to clinical disease.

Being able to discriminate between antibodies of the two types is of major importance to detect EHV-1 exposure and protect remaining horses from transmission. At the same time presence of EHV-4 should not initiate costly sanitation procedures and quarantine of affected horses which is indicated to prevent spread of EHV-1.

Antibodies to EHV are highly cross reactive and thus highly specific tests are needed for accurate discrimination between the two types.
