Equine Allergy Testing & Treatment


Your veterinarian will draw a small amount of blood from your horse and send the serum to us for allergy testing (also known as “serum IgE” testing.) The ACTT Allergy Test detects elevated levels of IgE antibodies in the blood for those specific allergens that are causing your horse’s allergic symptoms.

Our comprehensive equine panel is region-specific, and tests for up to 75 individual allergens. The panel includes weed, tree and grass pollens; molds, mites, insects, Culicoides, and feed ingredients.

Our test offers many advantages for the horse and owner alike:

  • No steroid or antihistamine interference
  • Simple blood draw is all that is required.
  • Minimal stress for the horse and owner
  • Accurate and reproducible results
  • Culicoides testing and treatment available



In consultation with your veterinarian, we can formulate an immunotherapy treatment kit which specifically targets your horse’s allergies. A thorough clinical history will also be considered when preparing treatment.

Immunotherapy is a safe and effective, long-term treatment that gradually builds the horse’s immunity to the specific allergens that are causing its discomfort.

Immunotherapy treatment (either shots or drops) with increasing amounts of allergen are given to the horse, beginning with a low dose and increasing until the highest tolerable concentration is reached. Our treatment sets are formulated by our lab using USDA approved allergen extracts.

Customized horse allergy treatment advantages include:

  • Fewer patient reactions
  • Increased owner compliance and satisfaction
  • Quicker improvement of symptoms

There is no cure for allergies, but they can be managed. With careful attention and dedication, immunotherapy is a highly effective treatment for allergies. As with any horse allergy medicine or treatment plan, immunotherapy can cause reactions such as increased pruritus, urticaria, face-rubbing, or in rare cases, agitation or lethargy. In the event of a reaction, please contact your veterinarian.

Steroid and antihistamine therapies are successful short-term options, but prolonged use of these drugs can have serious side effects.
