Are your symptoms
related to food reactions?

Food Sensitivity Test

The IgG Food Antibodies profile detects delayed reactions to over 80 commonly consumed foods. Food sensitivities can be challenging to identify and are not allergies. Symptoms of food sensitivities can include mood issues, headaches, gut problems, skin rashes, joint aches, and eventually even autoimmune diseases.

This test does not diagnose food allergies (IgE reactions), which can be life-threatening. The data from this test, along with your healthcare provider, can help inform dietary changes to improve your food sensitivity symptoms.

How will this test help me?

IgG antibodies play a crucial role in your immune system's response to food. However, their response can be delayed, which means you might not experience any symptoms or reactions until several hours or even days after consuming a particular food. This delay can make it difficult to pinpoint which food(s) triggered the reaction.

This is where testing comes in handy, as it can help identify the 'hidden' trigger food(s) and provide insights into your food sensitivities. Your test results offer insight on:

Dietary Guidance

Every food sensitivity test comes with a personalized summary of reactive foods and elimination diet guidance.

Intestinal Permeability

People with multiple food reactions may have an underlying issue with leaky gut syndrome, which increases the immune system's exposure to food particles that trigger reactions.

Immune Function

Although food itself is not inherently bad, the way our gut and immune system process it can be the root of the problem.

FAQs

Food Allergies:

  • Immediate onset; symptoms appear within minutes to hours after consuming the food
  • Allergies are typically permanent
  • Triggers the release of histamine, a chemical that causes allergic symptoms
  • Involves a specific type of antibody called IgE (not measured in the Food Sensitivity Test)
  • Usually diagnosed through skin prick testing or IgE blood testing by an allergist
  • Symptoms include hives, a stuffy or itchy nose, sneezing, itchy and teary eyes, vomiting, stomach cramps or diarrhea, swelling, shortness of breath or wheezing, and in severe cases, life-threatening anaphylaxis.

Food Sensitivities:

  • Delayed onset; symptoms may take hours to days to appear after consuming the food
  • Sensitivities are usually temporary
  • Does not trigger histamine release
  • Involves a different type of antibody called IgG (measured in the Food Sensitivity Test)
  • Symptoms can include gastrointestinal issues, such as bloating, diarrhea, and indigestion, as well as headaches, joint aches, skin rashes, fatigue, behavioral problems, and autoimmune disease.

Sometimes, you might notice foods on a test that you haven't consumed. There are a few reasons why this can happen:

  1. Hidden Ingredients: It's possible that you unknowingly consumed the food as a hidden ingredient. For instance, when you eat out at a restaurant, certain dishes may contain ingredients that you are unaware of. For example, you could have a reaction to seafood even if you don't directly eat fish or shellfish because some restaurants use fish or oyster sauce in their cooking. Another example is gluten added to turkey breast in commercial luncheon meats. Hidden ingredients can be found in various foods, so it's important to read labels and ask questions at restaurants. You can refer to our elimination diet guide, which provides information on hidden sources of certain foods and helps you identify if you have recently consumed that food.
  2. Cross Contamination: Cross contamination can occur in food manufacturing plants and restaurants, causing you to react to foods you haven't eaten. Food labels may indicate that a product was "manufactured on equipment that processes products containing [specific food]." This means that trace amounts of that specific food could be present in the product, even if it's not listed as an ingredient.
  3. Cross-Reactions: Sometimes, your immune system sees proteins in different foods or plants within the same family as the same, leading to cross-reactions. For example, if you don't eat cucumbers but they show up on your test, it could be because you recently consumed a food from the gourd/melon family, such as cantaloupe. Cucumbers and cantaloupes share similar proteins because they belong to the same family. Work with a healthcare provider to better understand cross-reactions and how to make necessary dietary changes.

Important: Food allergies can have a range of symptoms, including life-threatening anaphylaxis. If you have a known IgE-mediated food allergy, Genova DOES NOT recommend exposure to the food that may cause a reaction.

When testing for food sensitivities, it is suggested to eat a variety of foods for 2-3 weeks prior to testing (except for foods that are known to cause severe reactions). Doing so will help to ensure the presence of food antibodies in the blood to any problematic foods. IgG antibodies are expected to circulate in the blood for around 3 months. If you have not consumed the food prior to testing, no reaction to that food would be expected because there would be no circulating antibodies in the blood to measure.
