For starters, Coggins is a test not a disease. The Coggins Test is a diagnostic tool to analyze a horse’s blood for the presence of
antibodies to Equine Infectious Anemia Virus (EIAV). Blood is drawn by an accredited veterinarian and submitted with
paperwork, indicating the horse’s markings and current location, to an approved lab for testing with the Coggins Test. This test
is required by all states to cross the border with only a few exceptions. Some states also require it for change of ownership,
trail riding, and shows. Once tested, the paperwork is only good for a year, or less in some states, so the horse must be
retested.
