What Is An Agid Horse Test?
AGID-EIA is a high-performance agar gel immunodiffusion (AGID) test for the detection of antibodies to Equine Infectious Anemia (EIA) virus. Migration of antigen and antibody through agar gel results in formation of clearly defined precipitin lines to provide easy-to-interpret test results.
What does agid mean on a Coggins test?

THE COGGINS (AGID) and C-ELISA TESTS
The only way to accurately determine whether a horse is infected with the EIA virus is by identifying antibodies in the blood via agar gel immunodiffusion (AGID) or competitive enzyme linked immunoadsorbent assay (C-ELISA) tests.
What does it mean when a horse has Coggins?
Equine Infectious Anemia
A Coggins test is a blood test to identify if a horse is a carrier of Equine Infectious Anemia, a viral disease found in horses. A negative Coggins test is required for all travel between states and at most equine facilities.
What does a positive Coggins mean?
A “Coggins” is a blood test that detects antibodies to the disease Equine Infectious Anemia (EIA). This is a virus that can cause affected horses (or donkeys) to have fevers, anemia (low red blood cell count), edema (stocking up), or weight loss/muscle wasting.
Can a horse survive Coggins?
A Coggins test is good for one year and is required to get a health certificate for your horse. Sadly, most horses that are diagnosed with EIA are eventually euthanized due to the fact that any horse that is confirmed positive must be isolated at least 200 yards away from all other horses for its lifetime.
What does agid mean?

What does agid stand for?
AGID (Agar Gel Immunodiffusion Assay)
How do horses get Coggins disease?
EIA is transmitted from one horse to another through mosquito bites, horse flies, deer flies or stable flies that have fed on a different infected animal. This means that your horse does not even need to have come into direct contact with an infected animal in order to contract this disease.
How much does it cost to pull Coggins?
The cost of a Coggins test of course can vary but we have seen them in the range of $20 on the low side to $100 on the high side depending on how much work the vet has to do, the location of the horse and distance to the lab.
How do you prevent Coggins in horses?
Protecting Against EIA
- Continue annual Coggins tests for every horse.
- Don’t allow any horse on the property unless you have proof of current negative Coggins.
- Use fly repellent and physical barriers such as fly masks to reduce your horse’s exposure to biting flies.
How often do horses need Coggins?
Generally, yearly testing is required if you will be transporting your horse for any reason, but some states or organized shows may require a negative test within 6 months of importation.
Is Coggins contagious to other horses?
One of the main symptoms for the disease is fever, which makes it hard to diagnosis or differentiate from other fever-producing diseases like influenza and encephalitis. And although most infected horses show no symptoms, they remain contagious for life, endangering the health of other horses.
How long is a Coggins shot good for?
one year
Horses that are transported need to have Coggins papers to know they are negative for the disease to protect them and other horses. The Coggins test is good for one year and must be done by a USDA certified veterinarian.
What happens if my horse tests positive for Coggins?
For this reason, horses that test positive for Equine Infectious Anemia must either be euthanized, branded and strictly quarantined more 200 yards away from other horses for life, or transferred to a research facility.
What percentage of horses have Coggins?
The good news is that EIA is very rare in the US and new cases have continued to decrease annually, to a current level of approximately 0.02% positive of all horses tested. However, it remains important to continue to monitor for this disease in order to protect our healthy horse population.
What happens if a horse tests positive for EIA?
As there is no known treatment for EIA and infected horses become lifelong carriers posing a risk to other horses, any horse confirmed positive for EIA must be quarantined and isolated 200 yards away from all other horses. If appropriate isolation is not available, the owner may opt for humane euthanasia.
What causes equine infectious anemia?
Equine infectious anemia is caused by equine infectious anemia virus (EIAV), a lentivirus in the family Retroviridae (subfamily Orthoretrovirinae). Equine infectious anemia virus is reported to infect all members of the Equidae.
What is gel diffusion test used for?
Agar gel diffusion methods may be used as a rapid tool for determination of precipitating antibodies to mumps virus, and possibly may be applied to the study of antigenically related parainfluenza viruses.
What is the purpose of immunodiffusion?
Immunodiffusion testing is most often used to detect antibodies to fungal pathogens in dogs, such as Aspergillus fumigatus,3 Coccidioides immitis,4 and Blastomyces dermatitidis. It is also used to detect antibodies to Brucella canis.
What is double diffusion test?
In the gel double-diffusion test (Ouchterlony test), the virus-antibody reaction takes place in agar gel. Virus and antiserum are placed in opposite wells in an agar plate. Virus particles and antibodies then diffuse into the agar.
