Why Test?
Seasonal allergic reactions in horses can affect the skin, respiratory tract, and even digestion. Identifying specific sensitivities to pollens — such as grasses, weeds, and trees — is crucial for effective long-term management and avoiding unnecessary treatments. Horses of any breed, age, or sex can be affected, often with symptoms that peak during spring and summer.
Key Benefits
- Precise allergen identification: Based on specific IgE response
- HERBU scoring system: Results reported on a 0–5 scale for clinical clarity
- Minimally invasive: Requires only a blood sample — no sedation, shaving, or intradermal injections
- Highly reproducible: Standardized and validated laboratory method
-
Fast turnaround: Results ready in 2 to 7 working days
What’s Tested?
-
The test covers three key allergen classes relevant to seasonal exposures. Results are IgE-specific, avoiding cross-reactivity with IgG or CCDs.
