Allergy 107 (IgE Panel)

A comprehensive allergy test measuring immunoglobulin E (IgE) antibody responses to 107 common allergens across food, environmental, and contact categories. IgE-mediated allergies are the classic immediate-type reactions — hives, swelling, respiratory symptoms, or in severe cases, anaphylaxis. The panel identifies specific allergen sensitivities from a single blood draw, providing a detailed map of what the immune system is reacting to.

The Allergy 107 IgE Panel at Blessono Specialist Clinic tests for immunoglobulin E antibodies against 107 common allergens, providing a comprehensive picture of IgE-mediated (Type I) allergic sensitisation from a single blood draw. IgE-mediated allergies are the body's immediate-response immune reactions. When a sensitised individual encounters an allergen, IgE antibodies on the surface of mast cells and basophils trigger the release of histamine and other mediators within minutes, producing symptoms ranging from mild (itching, hives, runny nose) to severe (angioedema, bronchospasm, anaphylaxis). Understanding exactly which allergens trigger this response is the foundation of effective allergy management. The 107-allergen panel covers three major categories. Food allergens include common culprits such as shellfish, peanuts, tree nuts, cow's milk, egg, wheat, soy, fish, and stone fruits. Environmental allergens cover house dust mites, animal danders (cat, dog, horse), mould spores (Aspergillus, Alternaria, Cladosporium), grass pollens, tree pollens (birch, oak, cedar), and weed pollens (ragweed, mugwort). Contact allergens include latex, bee venom, wasp venom, and selected chemical compounds. The blood draw takes approximately 15 to 20 minutes, and the total appointment time including registration and consultation is roughly 30 minutes. Results are typically available within 5 to 10 working days and are presented in a detailed report showing the IgE level for each allergen tested, categorised by reactivity class from 0 (undetectable) to 6 (very high). A follow-up consultation with the medical team helps patients interpret the results and develop a practical avoidance strategy. This blood-based testing approach offers several advantages over skin prick testing: it is unaffected by antihistamine use, carries no risk of systemic allergic reaction during testing, and can be performed on patients with skin conditions such as eczema or dermatographism that make skin testing unreliable. The IgE panel tests for true allergies — distinct from food intolerances, which are mediated by IgG antibodies and produce delayed, less acute symptoms. Blessono offers a separate Food Intolerance IgG panel for clients experiencing delayed food reactions.
