Food Intolerance Test, in Collaboration with Cambridge Nutritional Sciences, UK (powered by Omega Diagnostics)










Food intolerance (also called Food sensitivity test) is a delayed immune response to certain foods, often linked to gut health, and can impact your daily life. Identifying and managing these trigger foods can help reduce symptoms and improve your well-being. The Food Intolerance test (IgG) comprises the FoodPrint® test (Omega Diagnostics; a subsidiary of Cambridge Nutritional Sciences, PLC, UK) which analyses up to 215 food and drink antigens for IgG antibodies using the state-of-the-art microarray technology.
Food intolerance is typically a slow response to certain ‘problem foods’ with milder nonspecific symptoms like bloating, headaches; tiredness, constipation or diarrhea, flatulence etc after eating certain foods e.g.lactose intolerance after milk; gluten sensitivity after wheat intake. This is in contrast to food allergy which is a more immediate and severe response to a food allergen usually with raised IgE type of antibodies.
Note:
This Food Intolerance test (IgG) is offered with complimentary post-test counselling and nutrition consultation (by experts from Omega Diagnostics; a subsidiary of Cambridge Nutritional Sciences, PLC, UK) to help interpret your results and guide you with a personalized diet plan.

The Food Intolerance test (IgG) helps identify food-specific IgG antibodies that may be linked to your symptoms. However, high IgG levels alone do not always indicate intolerance. Doctors and nutrition experts will consider your symptoms, medical history, and test results together to recommend dietary adjustments and design a personalized treatment plan. Your nutritionist can use the test results to pinpoint potential “problem foods” and design a personalised diet plan just for you. The plan may involve initially eliminating the foods that trigger reactions, suggesting healthy alternatives so your diet stays balanced and guiding safe reintroduction of foods after a few months. Most people follow this tailored plan for about three months, which allows the immune complexes to clear from the body and gives the gut time to heal. Patients usually notice a significant reduction in symptoms and an overall improvement in health and energy.
Food Intolerance (IgG) is quite different from an allergy. Quite simply put, food intolerance can be due to digestive issues when your body cannot properly digest certain foods due to lack of enzymes etc or IgG mediated immune response. Food Intolerance test (IgG) involves detection of IgG antibodies which cause a delayed reaction, with non-specific symptoms appearing hours to days after eating certain foods. These reactions are uncomfortable but generally not dangerous and managed by identifying trigger foods. In contrast, food allergies involve IgE antibodies and trigger an immediate response, often within minutes of consumption, which can cause hives, swelling, breathing difficulty, or even life-threatening anaphylaxis; may require strict avoidance of the allergen.
You may need the Food Intolerance test (IgG) if you often experience bloating, nausea, or stomach discomfort after eating certain foods, or if you have a family history of food intolerance. This test helps uncover sensitivities by detecting IgG antibodies, which your doctor or dietitian can use to create a diet plan tailored to your needs.
Managing food intolerance often involves avoiding trigger foods, finding safe alternatives, or sometimes taking enzyme supplements. An elimination diet (removing and gradually reintroducing foods) can also help, but this should only be followed under expert guidance to ensure proper nutrition and health.
No special preparation is required before the test, but follow your doctor’s instructions carefully. Inform your doctor about any medications or supplements you are taking, as these may affect your test results.
Lab test results may vary across different laboratories. Abnormal test results require an expert interpretation; therefore, never try to self-medicate at home based solely on these results, and always consult a doctor for a proper understanding of the test results.

What does Food Intolerance Test, in Collaboration with Cambridge Nutritional Sciences, UK (powered by Omega Diagnostics) measure?
Contains 215 testsThe {test name} detects IgG antibodies against 215 food substances across various food categories from blood samples. Food intolerance affects the digestive system. It may happen when your body cannot properly digest certain foods (for example, lactose intolerance from dairy) or a delayed IgG-related response against certain foods, leading to symptoms like bloating, headaches, or fatigue. These symptoms cause discomfort but usually are not dangerous.
In contrast, allergic reactions to certain foods are usually IgE mediated and can be severe and life-threatening. This Food Intolerance test (IgG) is different from a food allergy test, which detects IgE antibodies responsible for immediate allergic reactions.
The Cows Milk (Doodh), IgG test detect Immunoglobulin G (IgG) antibodies specifically directed against milk proteins. An elevated IgG level indicates that the immune system has identified milk proteins as potential threats, triggering a delayed hypersensitivity reaction. It is important to understand that this test doesn't diagnose milk allergy or traditional lactose intolerance. It's more related to food sensitivities or intolerances, which are different from allergies and can be caused by a variety of factors, including difficulty digesting or metabolizing milk proteins. In contrast, food allergies are usually immediate and IgE-mediated and tested by other tests which measure allergen specific IgE. Identifying such immune responses can help pinpoint food triggers, enabling doctors to recommend personalized dietary changes.

The Agar Agar, IgG test detects Immunoglobulin G (IgG) antibodies directed against agar agar. When the immune system identifies agar agar proteins as foreign, it may produce IgG antibodies, leading to a delayed hypersensitivity reaction. It is important to understand that this test doesn't diagnose allergy. It's more related to food sensitivities or intolerances, which are different from allergies and can be caused by a variety of factors, including difficulty digesting or metabolizing certain food stuffs. In contrast, food allergies are usually immediate and IgE-mediated and tested by other tests which measure allergen specific IgE . Identifying such immune responses can help pinpoint food triggers, enabling doctors to recommend personalized dietary changes.

The Alpha-Lactalbumin, IgG test detects Immunoglobulin G (IgG) antibodies specifically targeted against alpha-lactalbumin proteins. Alpha-lactalbumin is a major whey protein found in cow's milk. Elevated IgG levels indicate that the immune system may perceive this milk protein as a potential irritant, leading to a delayed hypersensitivity reaction. It is important to understand that this test doesn't diagnose allergy. It's more related to food sensitivities or intolerances, which are different from allergies and can be caused by a variety of factors, including difficulty digesting or metabolizing certain food stuffs. In contrast, food allergies are usually immediate and IgE-mediated and tested by other tests which measure allergen specific IgE . Identifying such immune responses can help pinpoint food triggers, enabling doctors to recommend personalized dietary changes.

The Transglutaminase, IgG test detects Immunoglobulin G (IgG) antibodies directed against tissue transglutaminase (tTG), an enzyme found in the lining of the small intestine. In individuals with celiac disease, the immune system mistakenly identifies this enzyme as harmful and produces IgG antibodies against it when gluten is consumed. Elevated levels of IgG antibodies indicate an immune response to gluten consumption. It is important to understand that this test doesn't diagnose allergy. It's more related to food sensitivities or intolerances, which are different from allergies and can be caused by a variety of factors, including difficulty digesting or metabolizing certain food stuffs. In contrast, food allergies are usually immediate and IgE-mediated and tested by other tests which measure allergen specific IgE . Identifying such immune responses can help pinpoint food triggers, enabling doctors to recommend personalized dietary changes.
