Food Allergy Test

Service Description

Our Food Allergy Test measures allergen-specific IgE antibodies in the blood, helping to detect potential IgE-mediated (Type I) allergic responses to a wide range of common foods. This type of testing is especially useful when skin prick testing is not possible, for example, if you're taking antihistamines, have active eczema or are at risk of a severe allergic reaction. Food allergies occur when the immune system reacts to a food protein that is normally harmless. Symptoms can range from mild itching or swelling to more serious reactions, including anaphylaxis. Approximately 1 in 3 people in Ireland now live with some form of allergy, and this number continues to grow. Allergies can also change over time, so repeat testing may be beneficial if your symptoms evolve. This blood test is performed using a laboratory-based immunoassay, providing a safe and accurate way to assess your body’s sensitisation to specific foods. A positive result indicates that your immune system has produced IgE antibodies to a certain food, but it doesn’t confirm that you will necessarily have symptoms. That's why it’s important to consider your results alongside your clinical history and any reactions you've experienced. We offer a targeted panel of food allergens, selected based on common triggers and clinical relevance. This focused approach avoids unnecessary screening while delivering the insights you need. What’s Tested: Dairy & Egg: Casein, Milk, Egg White, Egg Yolk Nuts & Seeds: Almond, Hazelnut, Peanut, Sesame Seed, Walnut Fruit & Vegetables: Apple, Carrot, Celery, Coconut, Garlic, Onion, Orange, Peach, Potato, Strawberry, Tomato Seafood: Cod Fish, Crab, Salmon, Shrimp, Tuna Other Foods: Chocolate, Corn, Oat, Rye Flour, Soyabean, Wheat Total IgE is also included for an overview of general allergic sensitivity. Important: This test does not detect non-IgE-related food intolerances (like lactose intolerance or coeliac disease), nor does it measure IgG antibody responses. If you’ve experienced symptoms such as skin reactions, digestive issues, or respiratory problems after eating, this test can help identify whether an IgE-mediated allergy might be to blame.
