  • What is a Food Intolerance?
    A food intolerance is a detrimental reaction to a specific food, beverage, food additive, or compound found in foods that produces symptoms in one or more organs and systems in the body. Unlike food allergies, food intolerance does not involve the immune system. When a person has a food intolerance, their body has difficulty digesting certain foods or ingredients found in food, leading to a range of symptoms. Common symptoms of food intolerance include bloating, gas, abdominal pain, diarrhea, nausea, headache, joint pain, fatigue, and skin rashes. Food intolerances can take hours, or even days before the patient suffers negative effects - making it difficult for the patient to identify which food/s they are reacting to. It is important to note that food intolerance is NOT the same as a food allergy, which is an immune system reaction that can cause severe symptoms or even a life-threatening reaction known as anaphylaxis. People with food intolerances can usually eat small amounts of the offending food without severe reactions.
  • What symptoms are linked to Food Intolerance?
    Food intolerance can cause a variety of symptoms that can affect the digestive system, skin, and other parts of the body. Common symptoms of food intolerance include bloating, diarrhea, abdominal pain, constipation, eczema, joint pain, fatigue, and headache. It is important to note that food intolerance is different from a food allergy, which can cause more severe symptoms and is a potentially life-threatening condition.
  • Do high IgG Antibody levels cause symptoms?
    When a food causes the body to produce elevated levels of IgG then these antibodies combine with the protein in the food to form an ‘antigen-antibody complex.’ These complexes are usually eliminated by other cells in the immune system. However, if the immune system is overloaded, these insoluble molecules become deposited in tissues within the body, causing chronic inflammation and the subsequent production of symptoms.
  • Why do foods cause IgG antibody responses?
    IgG antibodies are produced by the immune system in response to foreign substances, including food antigens. When certain foods are consumed, the immune system may identify them as harmful and produce IgG antibodies in response.
  • Is it possible to have high IgG levels and not experience symptoms?
    Yes, some people do have high IgG levels to certain foods but do not have any symptoms. This is most likely due to their immune system being extremely efficient at clearing away the antigen-antibody complexes before they have a chance to be deposited in the tissues and cause a problem. Certain common foods are more likely to show a positive result e.g., wheat, dairy, soya. The reason for this is that these foods are consumed on a regular basis in our diet and along with digestive issues can increase the likelihood that the body may react to them. While an elimination diet will always be the gold standard, the benefit of doing a food sensitivity test is that it will be able to quickly show which of the foods that are eaten on a regular basis are a potential problem. In addition, the tests are able to highlight more unusual foods which a person may not have considered removing from their diet.
  • How does the test work?
    Your blood sample is analysed by our certified partner laboratory. The test will accurately detect if IgG antibodies are present and to which foods, showing the exact level of IgG antibody reaction.
  • What type of sample collection is needed for this test?
    Our food inflammation test is a finger prick blood sample, the test requires around 4-5 drops of blood.
  • Why test for IgG antibodies to foods?
    The efficacy of a diet based on the measurement of IgG antibodies specific for food components has been demonstrated in a number of conditions, both in independent studies and clinical practice. Excellent results have been obtained in patients with migraine, lethargy, bloating, constipation, diarrhoea, flatulence, nausea, and irritable bowel syndrome (IBS).
  • What is the difference between a hair test and a blood test?
    The main difference between hair testing and blood testing for IgG antibodies is the method used to identify potential food sensitivities or intolerances. Blood testing is considered the more reliable and accurate method, while the scientific validity of hair testing is still a topic of debate among healthcare professionals.
  • What is the difference between an allergy and intolerance?
    Food intolerance and food allergy are two separate health issues with different underlying mechanisms and symptoms. Food allergy is an abnormal immune system response to a specific food protein that triggers the release of histamine and other chemicals in the body, leading to mild to severe reactions ranging from hives and itching to anaphylaxis, a potentially life-threatening condition. Symptoms usually appear immediately or within a few minutes up to two hours after eating the allergenic food. In contrast, food intolerance is a non-immunological, digestive system response to certain foods or ingredients. It means that the body lacks the enzymes to digest specific foods or cannot absorb certain nutrients properly, leading to a variety of symptoms, such as bloating, gas, abdominal pain, diarrhea, headache, and fatigue, among others. Symptoms may appear hours or even days after eating the offending food. The diagnostic tools and treatments for food allergy and food intolerance also differ. For food allergy, a skin test or a blood test can help identify the allergen, and strict avoidance of the allergenic food is the only way to prevent a reaction. Antihistamines and epinephrine can help relieve mild to severe allergic symptoms. Food intolerance is commonly diagnosed through an elimination diet or a food diary followed by reintroduction of foods one by one to identify the offending food. Or fast tracking your elimination diet by taking an IgG finger prick blood test! It is important to note that although food intolerance is non-life-threatening, it can still cause significant discomfort and affect the quality of life.
  • What is CRP? And why test for it?
    C-reactive protein (CRP) is a protein produced by the liver in response to inflammation in the body. CRP testing is important in medical diagnosis and treatment because it is a simple blood test that measures inflammation in the body, which can help diagnose infections, monitor inflammatory conditions, and predict the risk of heart attack.
  • How and when will I receive my results?
    All results are checked by our in-house experts prior to being sent to you, results are sent to you via PDF attachment to the email address that you supplied when placing your order. Once your sample has reached the laboratory it usually takes 3-5 working days for them to be sent to you.
  • How long do I wait before taking a retest?
    In general, we do not recommend retesting before 9 months to 1 year. The reason for this is because it is the embedding of immune complexes in bodily tissues that is responsible for inflammation and potential symptoms, as opposed to the antibodies themselves. Hence, we do not recommend retesting too soon, but advise a client to carefully review symptoms in the months following a test as nutritional changes are adopted. If the reintroduction of a food does not stimulate symptoms, this would suggest that the individual has reached a degree of tolerance to that food, with no need to retest.
  • Do you need to re-introduce foods before taking a FoodPrint ® test – if so, how long for?
    In general, we recommend that you follow your normal diet, so that the test will reflect what you usually eat. However, if you have specifically avoided a food, which you are not allergic to, for more than three months e.g., cow's milk, which used to be part of your normal diet and you would like it tested, we would recommend it is reintroduced. The recommendations are to reintroduce the food for 1 week eating a normal portion of that food at least once daily before taking your blood sample. If symptoms occur once the food is re-introduced, we recommend that you discontinue that food and conclude you are still sensitive to it. NB: If you have a known allergy to any food, coeliac disease or any food intolerance do not reintroduce this food into your diet. Food sensitivity tests do not identify IgE-mediated food allergies or provide information about coeliac disease, enzyme deficiencies such as lactose, histamine, tyramine or alcohol intolerance or indeed other chemical sensitivities, such as reactions to certain food additives.
  • Food Intolerances are commonly associated with delayed reactions up to 72 hours – why?
    It is important to differentiate a food intolerance (IgG) and a food allergy (IgE). A classic food allergy, such as a peanut or shellfish allergy, is usually characterised by an immediate and often severe reaction upon exposure to the offending food. Symptoms include sneezing, rashes, skin irritation, swelling of mucosal tissue and fatigue and could potentially be life threatening. Such allergic reactions usually involve IgE antibodies. Food sensitivity tends to be characterised by a delayed onset of symptoms and often involves the production of IgG antibodies which can lead to the formation of immune complexes and release of inflammatory markers. Symptoms may occur several days after eating the offending food, making it difficult to identify the cause. If the response to food and drink is immediate, please refer to your doctor or Allergy specialist to rule out a suspected allergy.
  • Is it possible that I am affected by foods that do not show up in my IgG food test?
    Yes - some foods may cause a classic allergic reaction involving the production of IgE antibodies. These will not be detected by any IgG food test. There are also many foods that can cause a reaction in the body without involving the immune system but produce symptoms similar to IgG reactions. For example, amines in chocolate, cheese and red wine may cause migraines; some food additives such as tartrazine can cause hives, rashes, and asthma; monosodium glutamate in Chinese dishes can produce sweating and dizziness; ‘Nightshade’ alkaloids in potatoes, tomatoes and peppers may affect the joints. Food intolerance may also be due to a deficiency of a particular enzyme, as in lactose intolerance. You should avoid any foods that you suspect are affecting you adversely.
  • What is the microbiome?
    There are trillions of microorganisms in our body. The ecosystem formed by these microorganisms is called the microbiome.
  • Does the microbiome change?
    Every person’s microbiome is unique, just like a fingerprint.
