IgG Reactivity to 40 Foods
Finger Prick Blood
This test measure’s your body’s immune response to 40 common foods that will help further refine your Gut Intelligence Test microbiome function recommendations and make the most informed food choices for your gut microbiome.
Foods that you are sensitive to are determined by an IgG immune response in your bloodstream. Viome’s Gut Intelligence test does not assess for systemic immune responses. A food found on your superfoods or enjoy lists may have important macronutrients and micronutrients which are beneficial for your microbiome, but for the time being, this food may need to be reconsidered due to a possible sensitivity.
Immunoglobulin G (IgG), the most abundant type of antibody, is found in all body fluids and protects against bacterial and viral infections. Antibodies are proteins made by the immune system to fight antigens, such as bacteria, viruses, toxins, or foreign substances. They are created in order to sound the alarm and attack when something that appears as foreign (antigens) enters the body. This reaction is meant to protect you, but in the case of food sensitivities, it can be frustrating.
This antibody is produced by nearly every cell in the body and is the most abundant in serum – the protein-rich part of your blood. IgG antibodies can cross membranes readily, including the placenta.
Elevated levels of IgG antibodies indicate food exposure is occurring in the bloodstream.
Elevated levels of IgG antibodies could indicate an immune response to a specific food.
Intestinal permeability can allow for some components of food or metabolic byproducts that would normally stay in the gut to cross the intestinal barrier and enter the bloodstream where they may trigger an IgG immune response.
IgG antibodies can contribute to systemic inflammation as well as related symptoms – such as brain fog, headaches, fatigue, mood disorders, and skin issues.
Food sensitivities are a delayed immune response of the Immunoglobulin G (IgG) antibody.
Viome’s Food Sensitivity test evaluates how reactive your immunoglobulin G, IgG, antibodies (the largest circulating antibody in the immune system) are in response to 40 different foods. Your results to these foods could either be:
Constipation or diarrhea
Unexplained weight loss or gain
Skin conditions – such as eczema, rosacea, acne or psoriasis
Asthma or asthma-like symptoms – wheezing, coughing, or difficulty breathing
When your body creates certain antibodies to a food, eating that food may cause an inflammatory response in the body. Because every body is unique, it is possible to be asymptomatic but still have a sensitivity to certain foods.
Our Food Sensitivity Intelligence Test is only available as an add-on product to be used in conjunction with your Gut Intelligence Test and is not sold as a standalone product.
This product will not provide any medical information or a diagnosis. Please consult a physician or healthcare professional before making dietary changes. To use this product, you must be 18 or older and be a U.S. resident.
What foods does the Food Sensitivity Intelligence test for? How does it work?
Viome tests for sensitivities to 40 (most commonly eaten) foods: Almond, apple, bakers yeast, banana, beef, bell pepper, blueberry, broccoli, cacao, casein, cashew, chicken, chickpea, cinnamon, coffee, cucumber, egg, garlic, ginger, gluten, grape, kale, maize, milk, oat, onion, orange, pork, potato, red wine, rice, salmon, sesame, shrimp, soybean, strawberry, tomato, tuna, wheat, whey.
Viome’s Food Sensitivity Intelligence test detects subtle levels of IgG antibodies in the bloodstream. It is evaluating for an IgG response, a combination of the four subclasses of IgG 1-4, to 40 different foods which you may or may not be sensitive to.
IgG antibodies are created by the body in response to a trigger, such as a particular food. There needs to be an ongoing presence of a trigger for IgG antibodies to be present. So, if you’ve eliminated a food you’re sensitive to or don’t eat certain foods very often, those foods may show up as a “Low” or “No Sensitivity Detected” in your Viome test results.
Can I purchase only a Food Sensitivity Intelligence Test?
No. Viome’s goal is to help you on your wellness journey via proper nutrition and diet recommendations. This is highly dependent on your gut microbiome. The Food Sensitivity Intelligence test cannot serve as the sole guide in your regular diet planning. Therefore, we see the Food Sensitivity Intelligence test as an important addition to the Gut Intelligence test.
Will the Food Sensitivity Intelligence test diagnose Celiac disease?
The Food Sensitivity Intelligence test is not a diagnostic test for Celiac Disease. If you do have Celiac Disease, you may or may not show an IgG response to gluten and wheat. Always go with your healthcare provider’s diagnosis and recommendations.
What can I expect the testing process to be like?
Conducting the Food Sensitivity Intelligence test at home is easy! All materials needed for the collection of 200 uL of blood, as well as detailed instructions, are sent to your home along with your kit.
How do I collect my blood sample for the Food Sensitivity Intelligence Test?
You can follow the instructions on the card included with your kit. You can also refer to this informative video.
Food Sensitivities vs Food Allergies: What is the difference?
Food allergies involve any adverse reaction (typically within an 8 hour period) to a food that triggers an immediate histamine response with severe symptoms such as anaphylaxis or hives. Food allergies are mediated by IgE antibodies and can be life-threatening.
Food allergies are not tested for with the Food Sensitivity Intelligence Test.
Food sensitivities can develop gradually, and symptoms typically occur hours (48- 72 hours) after eating particular foods where an individual could experience certain symptoms such as constipation, diarrhea, flatulence, abdominal pain, headaches/migraines, skin rashes, acne, joint pain, insomnia or fatigue.
Food sensitivities are mediated by IgG antibodies (the largest circulating antibody in the immune system) and are non-life threatening.
With a sustained or longer-lasting immune response, individuals will typically eat a variety of foods in the time it takes for symptoms to appear, making it difficult sometimes to detect a pattern between the specific foods ingested and symptom development.
Is the Food Sensitivity Intelligence test available to me?
Viome's Foods Sensitivity Intelligence test is currently only available in certain states within the United States. It is only available for adults over the age of 18.
The test is available ONLY in these states (If your state is not listed, Viome cannot ship kits to your state, nor process samples sent from your state):
How do I prepare for the Food Sensitivity Intelligence testing?
All that you need to do to prepare is drink a glass of water about thirty minutes before collecting your blood sample. You can collect your sample any time of day. Do not collect the sample within 1 hour after vigorous exercise.
