9257. Allergen. Extract. Wheat flour (f4), IgE antibodies
Description
Wheat allergy is among the 14 major food allergies worldwide and may manifest in both food and respiratory forms. The immune response is directed against wheat proteins – gluten (gliadin), hordein, avenin, zein, and others. Clinical manifestations include cutaneous reactions (atopic dermatitis, urticaria, angioedema), gastrointestinal disturbances (cheilitis, gastritis, colitis), and respiratory symptoms (allergic rhinitis, baker's asthma). Symptoms typically appear within minutes of exposure, and less commonly within up to two hours. Determination of specific IgE antibodies to wheat proteins is recommended for the identification of sensitization.
When and who needs the test?
- To diagnose sensitization to wheat proteins, especially if food or respiratory allergies are suspected.
- For respiratory symptoms that are exacerbated by contact with flour (baker's asthma).
- To help decide on treatment strategies and the feasibility of allergen-specific therapy (ASIT).
