TVMDL offers two methods of detecting EIA antibodies, an agar gel immunodiffusion, AGID, method or an enzyme-linked immunosorbent assay, ELISA.
Equine Infectious Anemia, EIA, is a viral disease spread by insect bites and poor hygiene practices, contaminated needles, and other instruments. Testing is performed to determine if a horse has been exposed to the virus and has produced an antibody response. Colloquially, this type of testing is often referred to as Coggins testing, named after Dr. Leroy Coggins, a virologist who developed the test for EIA.
The Texas A&M Veterinary Medical Diagnostic Laboratory, TVMDL, offers two methods of detecting EIA antibodies, an agar gel immunodiffusion, AGID, method or an enzyme-linked immunosorbent assay, ELISA. TVMDL encourages clients schedule a consultation with a veterinary diagnostician to determine the correct testing method.
