Intolerance & Allergy Tests

Yes. Advances in laboratory testing mean a small blood sample can now be collected conveniently at home and sent to a laboratory for analysis. The Check My Body Health Premium Allergy Test includes everything you need to collect your sample at home. Your sample is analysed using advanced specific IgE allergy testing technology, measuring your immune response against 174 food and environmental allergens, with secure online results and professional support available after testing. For many people, accessing allergy testing through traditional healthcare routes may involve appointments, referrals and waiting times before specific allergens are investigated. Our home-to-lab allergy test provides a fast and convenient way to access comprehensive IgE allergy insights without unnecessary delays, helping you take the next step in understanding your symptoms sooner. Your results include access to a virtual consultation with a registered dietitian, helping you understand your report, discuss potential triggers and consider practical next steps.

An IgE allergy blood test is a laboratory test that measures levels of allergen-specific Immunoglobulin E (IgE) antibodies in your blood. IgE antibodies are produced by your immune system when it reacts to substances known as allergens. Measuring specific IgE levels can help identify possible allergic sensitisation to triggers such as foods, pollen, dust mites, moulds and animal allergens. The Check My Body Health Premium Allergy Test uses advanced laboratory technology to measure specific IgE antibodies against 174 food and environmental allergens from one simple home blood sample. Your results should always be reviewed alongside your symptoms and medical history, which is why we include access to professional support to help you understand your results.

Yes. Specific IgE blood testing is a clinically recognised method used within allergy assessment pathways. The NHS explains that allergy investigations may include blood testing, while NICE guidance recommends serum-specific IgE testing as one option when assessing suspected IgE-mediated allergies alongside clinical history.

An allergy and an intolerance are different types of reactions within the body. A food allergy involves the immune system and can trigger symptoms after exposure to even a small amount of an allergen. IgE-mediated allergies occur when the immune system produces Immunoglobulin E (IgE) antibodies against a specific substance, which can lead to allergic symptoms. A food intolerance does not usually involve the immune system in the same way and is often linked to difficulty processing certain foods. Intolerance symptoms are generally associated with digestion and may depend on the amount consumed. The NHS explains: “A food intolerance is difficulty digesting certain foods and having an unpleasant physical reaction to them.” and explains that unlike allergies, food intolerance: • does not involve the immune system • is not the same as a food allergy Allergy UK explains: "That food allergy involves the immune system reacting to a food, whereas food intolerance does not involve the immune system in the same way." Our Premium Allergy Test measures specific IgE antibodies across 174 food and environmental allergens, helping identify potential allergic sensitisation. It is designed specifically for allergy investigation and is different from food intolerance testing.

You may have a known allergy; so let’s help you to interpret sensitivity results to this item. Scenario 1: The item you are allergic to shows as a moderate or high reactivity item. This means that as well as a food allergy you have food sensitivity. If you have already removed this item from your diet you do not need to take any action. If you have not removed it previously, it is worth considering doing so, however we would not recommend reintroduction following the elimination diet. Scenario 2: The item you are allergic to shows as a no reactivity item. This means that you do not have food sensitivity to this item however the result does not question or contradict the presence of your food allergy to the item. It does NOT mean you should reintroduce the item to your diet, you should respect the symptoms or test results you have had previously with regards to allergy. Remember this test does not test for allergy. Everyday FoodsIt is common for a food item consumed in the daily diet or very frequently, to test as a moderate or high sensitivity item. This can happen with food sensitivity and may be due to the body suddenly struggling to process or breakdown particular constituents of the food. This could be caused by overconsumption of a food group or could be down to an imbalance in gut bacteria or the presence of low-level inflammation in the gut. Whatever the cause do not despair. We are talking about food sensitivity and NOT allergy; therefore completing a food elimination diet with subsequent reintroduction can help. This may mean you need to eliminate a favourite food or staple in your diet for a period of weeks but you will be able to reintroduce theitem. Eliminating food items for a period of time can allow the gut time to ‘rest’ from trigger foods and the reintroduction of items can allow you to assess how a food or food group makes you feel. Gut NourishmentIn most cases carrying out an elimination diet is enough to improve symptoms and allow for a greater understanding of any foods, which aren’t agreeing with the body. It is also worth considering the nourishment of the digestive tract and addressing any gut bacteria imbalances to further improve gut function and reduce digestive symptoms.
