This is truly the best way to start your allergy diagnosis and treatment journey. A full allergy MOT for the body. For people with multiple allergen sensitivities or those experiencing unclear clinical symptoms, the traditional method of determining individual allergens can be both costly and time-consuming. In such situations, a comprehensive allergen screening provides a clear understanding of the patient's sensitisation profile and serves as a potent tool for accurate diagnosis and preventing exposure to allergens. The identification of allergen-specific IgE antibodies in the blood serum plays a critical role in diagnosing type 1 allergies and this test allows simultaneous testing of 295 common allergens, giving you a clear baseline for further exploration of specific allergens. Allergy testing is often a "stab in the dark" and this test allows you to avoid that entirely.

Biomarkers Tested

Immunoglobulin E (IgE) is a protein associated with allergic reactions that is normally found in very small amounts in the blood. IgE functions as part of the body's immune system (its defence against 'intruders').
