Know more about this test

Food intolerance or sensitivity means the body struggles to digest certain foods, leading to delayed symptoms like bloating, stomach pain, nausea, or vomiting. The Food Intolerance Test, in Collaboration with Cambridge Nutritional Sciences, UK (powered by Omega Diagnostics), offered in partnership with Omega Diagnostics (a subsidiary of Cambridge Nutritional Sciences Plc, UK), helps detect Immunoglobulin G (IgG) antibodies linked to specific foods, such as gluten, to identify potential triggers.

In contrast, a food allergy involves an immediate immune response through immunoglobulin E (IgE) antibodies, causing rapid symptoms like itching, hives, swelling, or even life-threatening anaphylaxis. While both involve the immune system, IgG reactions are slower and digestion-related, whereas IgE reactions are sudden and systemic. Knowing the difference aids in accurate diagnosis and proper management.

Note:

This UK-based test checks for IgG-linked food intolerances, not IgE-mediated allergies. If you experience sudden allergic reactions (e.g., swelling or difficulty breathing), consult a doctor for allergy testing.
Free dietary consultation is available with this test.

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

Food intolerance means you may be able to eat small amounts of food, but larger portions can cause issues like bloating, nausea, diarrhea, or constipation. It can be due to a lack of enzymes needed to digest certain foods or sometimes a reaction to additives or naturally occurring compounds in foods. Your body mistakes these food products as a threat and produces IgG antibodies which can result in inflammation and discomfort in the stomach. This often happens because of damage to the gut lining, causing inflammation and poor digestion. IgG antibodies may show up hours or even days after eating the food, leading to delayed symptoms like tiredness, headaches, or irritable bowel syndrome (IBS).

The Food Intolerance Test, in Collaboration with Cambridge Nutritional Sciences, UK (powered by Omega Diagnostics) checks IgG antibodies against various food items to help identify potential trigger foods. However, high IgG levels alone do not always indicate intolerance. Doctors and nutrition experts consider your symptoms, medical history, and test results together to recommend dietary adjustments and design a personalized treatment plan.

Food intolerance is not the same as a food allergy. While food allergy is IgE-mediated and used to diagnose immediate allergic reactions, food intolerance is IgG-mediated and used to identify food sensitivities with delayed responses. Food allergies can be life-threatening, whereas food intolerances are generally digestion-related and not life-threatening.

You may need the food intolerance test 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.

As part of this test package, you receive a one-time complimentary dietary consultation with expert nutritionists to help interpret your results and guide you with a personalized diet plan.

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

Contains 215 tests

The Food Intolerance Test, in Collaboration with Cambridge Nutritional Sciences, UK (powered by Omega Diagnostics) detects IgG antibodies against 215 food substances across various food categories. These antibodies may appear hours or days after eating and indicate the body's delayed reaction to specific foods.

This test is different from a food allergy test, which detects IgE antibodies responsible for immediate allergic reactions. Food intolerance is usually not life-threatening but can affect your digestion, energy levels, and long-term health if unmanaged.

Cows Milk (Doodh), IgG

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 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 .

Transglutaminase, IgG

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.
