What is a coggins test and why do I need one?
The Coggins test checks for Equine Infectious Anemia (EIA) antibodies in the horse's blood. Blood samples must be sent to a state approved laboratory. This test is often needed to take your horse to a show and whenever you transport your horse across state lines. It is to prove to others your horse is safe to be around their horses. Some states now require a negative Coggins test on a horse before he can be sold. Before you travel check to see how recent a test is required because it differs from place to place.

Once you have a negative Coggins further testing is not required for your own peace of mind. Your horse will not become EIA positive unless he develops a serious, febrile illness after contact with a horse of unknown EIA status. You may be required to have a test done yearly to show or transport your horse, so other people will know your horse is safe.
