What Is Coggins Disease in Horses?
Coggins is not a disease, but rather the test performed for equine infectious anemia virus (EIAV). Most horse owners are more familiar with the term ‘Coggins’ than the disease it tests for because state regulations require a negative Coggins certificate before a horse can participate in a show or be transported out of state. In some areas, a certificate is required before a horse can be sold. Tests must be repeated annually and in some states, every six months.
