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?

🧬 About the Results
- 
Results are expressed using the HERBU score (0–600)
