Advanced equine diagnostics for improved patient care

 A tall, vertical shape with straight sides and semicircular ends, resembling a capsule or pill, outlined in black on a white background—ideal for signage at a pet clinic or veterinarian's office. The image is a solid light gray background with no visible objects, text, or people—ideal for use in Animal Hospital or Vet settings seeking a neutral backdrop.

Coggins Test: What It Is and Why It Matters

The Coggins test is a critical blood test for horses to detect Equine Infectious Anemia (EIA), a serious and potentially fatal viral disease.

What is Equine Infectious Anemia (EIA)?

EIA is a contagious disease transmitted by biting insects like horseflies and deer flies. It weakens the immune system, leaving horses susceptible to infections and other health problems.

Why is the Coggins Test Important?
  • Legal Requirement: In many states and countries, a negative Coggins test is legally required for:
    • Interstate and international horse travel
    • Entry into shows, competitions, and boarding facilities
    • Sale or purchase of horses
  • Disease Prevention: Regular testing helps:
    • Identify infected horses early on
    • Prevent the spread of EIA to other horses
    • Protect the health of the horse population

What Happens if the Test is Positive?

A positive Coggins test result indicates that the horse has been exposed to the EIA virus.

  • Important Note: A positive result does not always mean the horse is actively sick.
  • Further Testing: If the initial test is positive, further testing is required to confirm the diagnosis.
  • Quarantine: Infected horses must be isolated to prevent the spread of the disease.

How Does the Coggins Test Work?

The test detects antibodies in the horse’s blood that the immune system produces in response to the EIA virus.
