The Food Intolerance Test (IgG) is an at-home test that measures your body's immune response to over 200 commonly consumed foods. It helps identify potential food intolerances and provides guidance for creating a personalized elimination diet.

Please note: this test identifies food intolerances (immune reactions linked to IgG antibodies), not food allergies (IgE-mediated reactions), which require different testing and can be medically urgent. If you suspect a food allergy, please consult your doctor.

Simply collect your sample at home using our finger-prick kit and mail it to our lab. Your results include a personalized food report to support more informed dietary choices.

Tests your body’s IgG response to 200+ foods

Easy, at-home finger prick sample collection.

Screens for immune reactions to everyday foods

Details

This test uses ELISA-based technology to measure IgG antibody levels to over 200 different foods.

The panel includes commonly recognized triggers of food intolerance—such as dairy, eggs, wheat, soy, and nuts—as well as less obvious items that can still cause sensitivities, like cola nut, rice, sunflower, and sesame seeds.


Conditions and symptoms that have been associated with elevated IgG food antibodies include:

  1. Irritable Bowel Syndrome (IBS)
  2. Inflammatory conditions, including arthritis
  3. Migraines and chronic headaches
  4. Asthma and other respiratory issues
  5. Digestive concerns such as bloating, gas, constipation, and diarrhea
  6. General fatigue or a sense of “not feeling well”
  7. Weight management challenges, including obesity
  8. Skin issues such as rashes and eczema

Sample Requirement:

A small blood sample collected using the provided lancet and deposited into the included collection tube.

FAQ'S

FREQUENTLY ASKED QUESTIONS

Intolerance vs. Sensitivity vs. Allergy

Understanding the differences between these three types of food reactions is key to managing your health effectively. While they can share some symptoms, their underlying causes and impacts are very different.

🧪 Food Intolerance
Food intolerance occurs when the body lacks the necessary enzymes to properly digest certain foods. This is not an immune response, but rather a digestive issue.

Common triggers and symptoms may include:

  • Lactose intolerance (inability to digest dairy)
  • Sensitivity to food additives (e.g., sulfites, MSG)
  • Irritable bowel syndrome (IBS)
  • Symptoms influenced by stress or psychological factors

🧬 Food Sensitivity
Food sensitivity involves an immune-mediated response—often delayed—that can evolve over time. It is typically associated with elevated IgG antibodies rather than the immediate IgE response seen in food allergies.

Possible triggers include:

  • Certain foods (often based on overconsumption or gut imbalance)
  • Environmental allergens
  • Medications
  • Cross-reactivity between related food groups

⚠️ Food Allergy
A food allergy is a more serious and immediate immune reaction, usually triggered by an IgE antibody response to specific food proteins. This hypersensitivity can affect multiple organ systems and may result in a range of symptoms—from mild to life-threatening.

Common facts about food allergies:

  • Symptoms can include hives, swelling, digestive issues, breathing difficulties, or anaphylaxis
  • Often begins in childhood—many children outgrow food allergies, but not all
  • Requires medical diagnosis and, in some cases, emergency treatment (e.g., EpiPen)

🔍 Important Note:
While food intolerances and food allergies can produce similar symptoms—like digestive discomfort or fatigue—they are very different in nature. Intolerances are not immune-related, whereas allergies involve a serious immune reaction. This often leads to confusion, so proper testing and medical consultation are recommended.

Is it safe to start with a food elimination diet?

Yes, you can! Starting with a food elimination diet is a common approach, but it can be challenging to pinpoint the exact foods causing symptoms.


This is because IgG food sensitivities often cause delayed reactions, meaning symptoms may not appear until hours—or even days—after eating the offending food. As a result, elimination diets based on guesswork can take a long time and may still miss key triggers.


That’s where the IgG Food Intolerance Test comes in. It provides quantitative results to help guide your elimination process.

  • Step 1: Begin by eliminating the foods that show the highest reactivity in your test results.
  • Step 2: Gradually reintroduce foods that showed lower reactivity, one at a time, while monitoring for symptoms.

This approach can make your elimination diet far more targeted, efficient, and effective.

How frequently should testing be repeated?

It’s generally recommended to retest every 6 to 12 months, especially if you’ve made significant dietary changes based on your initial results. This gives your immune system time to reset and allows you to see if any sensitivities have improved or resolved.


If symptoms persist or new ones arise, you may consider testing sooner. For individuals following a strict elimination diet, retesting can help guide safe food reintroductions and further refine dietary choices.


Always consult with a healthcare practitioner for personalized guidance on when and how to retest.

What Is IgG & Why Test for It?

IgG (Immunoglobulin G) is a type of antibody produced by your immune system in response to specific foods. Elevated IgG levels may suggest that your body is reacting to certain foods, potentially contributing to symptoms like digestive issues, headaches, fatigue, or skin problems. Measuring IgG levels can help guide elimination diets and support overall wellness.



Does this test diagnose food allergies?

No. This test measures IgG-mediated food sensitivities, not IgE-mediated food allergies, which can cause immediate and potentially life-threatening reactions. If you suspect a food allergy, consult an allergist for proper testing.

Do I need to fast before taking the test

No fasting is required. You can take the test at any time of day, regardless of when you last ate.

How long will it take to receive my results?

You’ll receive your personalized report within 5 to 10 business days after your sample arrives at our lab.

Will I understand my results without medical training?

Yes. The report is designed to be clear and easy to understand, with a food reactivity scale, helpful visuals, and guidance on which foods to consider removing or reintroducing.

Can food sensitivities change over time?

Yes. Sensitivities may develop, worsen, or improve depending on factors like stress, gut health, medication use, or diet. That’s why retesting every 6 to 12 months is often recommended.
