Equine Infectious Anaemia (EIA)

EIA commonly known as swamp fever is a viral disease of horses caused by the lentivirus equine infectious anaemia virus (EIAV). Due to the persistence of EIAV in infected horses, detection of serum antibody to EIAV confirms the diagnosis of EIA virus infection.

Whilst ELISA tests are quicker than other techniques the OIE recommend that all positive tests are confirmed by the Agar Gel Immunodiffusion (AGID) or Coggin's Test. Therefore at Biobest we have chosen to provide the AGID test. Precipitating antibody is rapidly produced as a result of EIA infection, and can be detected by the AGID (Coggin's) Test. Specific reactions are indicated by precipitin lines between the EIA antigen and the test serum and confirmed by their identity with the reaction between the antigen and the positive standard serum. Horses in the first 2-3 weeks after infection will usually give negative serological reactions. In rare cases the post-infection time prior to the appearance of detectable antibody may extend up to 60 days

Tests will be performed daily Monday to Thursday and results available after a 24 hour incubation period. Urgent tests may be set up at additional times if required, please contact us to discuss this.
