Veterinary Technician Practice Exam

What is the purpose of the Coggins test?

1. To test for rabies

2. To diagnose Equine Infectious Anemia

3. To check for West Nile Virus

4. To screen for dental disease

The correct answer is: To diagnose Equine Infectious Anemia

The Coggins test is specifically designed to diagnose Equine Infectious Anemia (EIA), a viral disease that affects horses. This test detects antibodies against the EIA virus in the horse's blood, which is crucial for preventing the spread of this disease, often through vectors like biting flies. A positive result indicates that the horse is infected with EIA, while a negative result means the horse is not infected and can be transported or shown without risk of spreading the disease to other horses. Therefore, the relevance of the Coggins test lies in its role in equine health management and biosecurity practices within the horse community. The other options refer to different diseases and testing protocols irrelevant to the Coggins test. For instance, rabies testing involves different methods, as does diagnosing West Nile Virus, each requiring specific assays reflecting the unique pathogens. Screening for dental disease typically involves physical examination and possibly radiographs, rather than serological tests like the Coggins.
