When the presence of a food allergy is established, strict avoidance of the responsible allergen is the gold-standard approach. The taxonomic relationship between different protein sources should also be considered to avoid cross-reactivity. For example, if beef does not seem to be a suitable ingredient, then bison, venison, lamb and/or milk might also not be suitable. This also applies to chicken meat and other bird or egg products. If the trial appears to have been performed correctly, but the patient did not improve or only improved slightly, then it is probably suffering from atopic dermatitis and reacting to environmental allergens.

PAX® Serum Test and/or Artuvetrin® Skin Test can identify which environmental allergens the patient is reacting to, and help design an appropriate immunotherapy to treat the cause of the allergy.

Artuvetrin® Therapy is the only licensed immunotherapy in Europe and is the immunotherapy product of choice under the European veterinary medicine regulations (Directive 2004/28/EC).
