Allergy & Intolerance Test
Allergy & Intolerance Test
The Welzo Allergy & Intolerance Test is a comprehensive diagnostic panel designed to identify your body’s immune responses to both food-based and environmental triggers. Many individuals suffer from symptoms such as bloating, fatigue, nasal congestion, headaches, or skin irritation without understanding the underlying cause. This test distinguishes between true allergies, which involve an IgE-mediated immune response and may result in rapid-onset reactions, and intolerances, which are typically non-IgE-mediated and produce delayed digestive or systemic symptoms.
Drawing on validated clinical research and immunological protocols used in UK-based allergy clinics, this test measures your immune system’s reactivity to a range of common foods and environmental allergens. Studies published in the Journal of Allergy and Clinical Immunology and research by institutions such as Imperial College London have highlighted the value of combined allergy and intolerance testing in the early identification and management of chronic inflammatory conditions, especially in cases where symptoms are vague or persist despite other investigations.
Whether you are experiencing gastrointestinal discomfort, brain fog, skin problems, sinus symptoms, or energy fluctuations, this test offers data-driven insights that can help guide dietary and lifestyle adjustments. It’s a valuable tool for personalising nutrition, improving gut health, and reducing unnecessary inflammation.
What Does This Test For?
This test evaluates your body’s immune reactions to both dietary and environmental substances, helping pinpoint triggers of allergic and intolerance symptoms. It provides valuable insights to guide avoidance strategies and treatments, improving respiratory health, digestion, and overall quality of life.
