The AAEP Field Diagnostic Guidelines provide step-by-step instruction for the diagnostic work-up and management of clinical syndromes commonly encountered in equine practice. They are intended to help practitioners determine appropriate samples and tests necessary to achieve a definitive diagnosis while implementing appropriate biosecurity measures.
Considerations for veterinarians approaching cases of unknown etiology:
- If there is any potential for infectious disease, veterinarians should assume a worst-case scenario and implement appropriate biosecurity practices until infectious causes of disease are ruled out. Detailed instructions for biosecurity on premises and at equine events are provided in the AAEP Biosecurity Guidelines.
- If a reportable disease is suspected or confirmed, state animal health officials (and federal, as appropriate) should be notified immediately.
- Veterinarians are encouraged to communicate directly with diagnostic laboratories for additional guidance in proper sampling technique, test selection, and shipping instructions to ensure that diagnostic submissions are of optimal quality and yield. General guidance can be found in AAEP Diagnostic Sample Collection, Handling, and Transport Guide.
- Additional detailed information regarding diagnostic recommendations for specific diseases can be found in the AAEP Guidelines Library.
Up-to-date information regarding cases and outbreaks of infectious and/or reportable disease can be found at the Equine Disease Communication Center (EDCC).
These guidelines were developed by the Field Guidelines Subcommittee of the AAEP Infectious Disease Committee.
