Why a Horse Needs a Coggins Test to go to a Horse Show

The Coggins test was developed over 25 years ago by Dr. Leroy Coggins. It is a blood test to see if a horse is infected with the Equine Infectious Anemia virus or EIA. EIA affects the horse's immune system and makes him more susceptible to other diseases as well as causing damage to organs like the liver.

EIA is transmitted by blood-sucking insects or using a contaminated needle or instrument. There is no cure for this disease which is eventually fatal. Because of this, the disease is controlled by having horses tested periodically to insure that diseased horses are not allowed to mingle with healthy horses.

Horse shows, organized trail rides or other events require a negative Coggins test from all participants to insure the health and safety of all.
