Coggins Testing

If you are in need of a Coggins test for your Equine, Northwest Veterinary and Supply has 1 certified veterinarian that can preform this testing. We offer same day testing and results if needed.

Equine Infectious Anemia (EIA) is an infectious and potentially fatal viral disease of horses. No vaccine or treatment exists for the disease. Clinical signs of EIA include fever, weight loss, icterus (yellowing of body tissues), anemia, swelling in the limbs, and weakness. However, not all equids infected with the equine infectious anemia virus (EIAV) show signs of illness, and these animals serve as inapparent carriers.

Coggins testing has the ability to identify carrier animals. Although other serologic tests have been developed and approved for diagnosing EIA, the Coggins test is internationally recognized as the standard to which all other tests are compared. Currently, the Coggins test or some of the newer tests for EIAV are commonly required when moving horses within and among States.
