About this test
Measure IgG reactivity to 96 or 204 foods to help plan an elimination diet with guidance. This test measures IgG reactivity, which is not a diagnosis of intolerance or allergy.
For adults 18 and older. Not available in NY. Not recommended during pregnancy or with a history of an eating disorder.
Finally figure out if food sensitivities might be making you feel that way
If you have hives, swelling or trouble breathing after eating, seek medical care.
- Bloating
- Stomach pain
- Abdominal pain
- Indigestion
- Gastrointestinal distress
- Headaches

What does this test measure?
The Immunoglobulin G (IgG) test measures the levels of IgG antibodies in your blood, checking for sensitivity to 96 foods, or 204 with the Comprehensive test.

Plan an elimination diet
Use your results to plan a two-part elimination diet, ideally with a clinician or dietitian.
We’ll help you understand what they mean and what to do next. Because knowledge is the first step to feeling better.
What your results tell you
Each food is rated from Class 0 to Class 3, so you can see where to start.
- Help prioritizing your temporary elimination diet
- Tailored suggestions about what to do next
- Personalized information and education
- Results reviewed by a licensed clinician
Higher reactivity doesn’t always mean a food causes symptoms. Your results are a starting point for a two-part elimination diet.
Sensitivity, intolerance, allergy and gut microbiome are four different things
They get used interchangeably. They aren’t. Here is what each one means, and which one this test measures.
Food sensitivity
A measurable IgG immune response to specific food proteins. Not the same as an allergy. Reactivity is information, not a verdict.
What this test measures
- Mechanism
- IgG reactivity shows exposure to a food protein. It does not on its own mean a food causes symptoms.
- Timing
- Hours to days after eating, if symptoms appear at all.
- Symptoms
- Common symptoms include headaches, bloating, stomach pain/discomfort and indigestion. Note some of these symptoms overlap with food intolerance symptoms.
- How to test
- IgG reactivity testing, plus a structured two-part elimination diet.
This test measures IgG reactivity across 96 or 204 foods. Results show what your immune system has reacted to, not what you must eliminate.See what’s tested

Do you ever feel like you may have certain symptoms related to foods, such as headaches, stomach pain, or diarrhea? Do you feel you may want to try eliminating possible triggers, but you are not sure where to start?
Our Food Sensitivity Test measures your body’s IgG immune response to up to 204 common foods.
A temporary elimination diet is a way to help you pinpoint foods that may be causing your symptoms. This test is not the same as an intolerance or food allergy test. Food allergies are mediated by IgE antibodies, and symptoms for food allergies typically occur within minutes to hours of exposure. These symptoms are often severe and potentially life-threatening. Food sensitivities, on the other hand, are often marked by a low and slow onset, and involve an entirely different antibody—IgG. In addition, this test does not test for lactose intolerance, IBS, or celiac disease.
Your body may have an immune response to foods you eat, which may manifest as physical symptoms. Some of our customers take the Food Sensitivity Test because they experience symptoms like:
Bloating
Headaches
Indigestion
Gastrointestinal (GI) distress
Stomach or abdominal pain
If you are looking to add a potentially ‘problematic’ food back into your diet to see if you’re still reactive to it on your test results, it’s recommended to consume that food for about 4-6 weeks prior to testing.
The results of your Everlywell Food Sensitivity Test are intended to be used to guide a temporary elimination diet with an add-back challenge. This is a critical step in helping pinpoint which foods may be causing your unwanted symptoms.
We understand that food elimination and restriction can lead to or trigger disordered eating behavior. For this reason, it is not recommended to take the Food Sensitivity Test if you currently have or are in recovery from an eating disorder (i.e., anorexia nervosa, bulimia nervosa, and binge eating disorder).
It is also not recommended to use the results of your Food Sensitivity Test to achieve weight loss. Eating a balanced diet is important and your results are not intended to strictly limit your consumption and inhibit your ability to obtain necessary calories and nutrients from food.
Due to the specific nutritional needs of pregnant and breastfeeding women, elimination diets are not recommended. It’s best to speak with your healthcare provider for advice if you are experiencing unwanted symptoms.
The result shows IgG reactivity to the foods tested. It does not diagnose a food allergy or intolerance, and it does not on its own mean a food causes symptoms. Samples are processed in CLIA-certified labs.
Your IgG reactivity to 96 or 204 foods, broken down in a clear, easy-to-read, color-coded report: a data-backed picture of how your body responds to certain foods.
Your results come with guidance on how to plan a two-part elimination diet based on your specific reactivity levels, plus help understanding what they mean and what to do next.
A sensitivity is a measurable IgG immune response to specific food proteins. An allergy is an IgE-mediated immune reaction that can be immediate and severe. An intolerance is a non-immune digestive response: your body has trouble breaking a food down.
