The Food Intolerance Test is an at-home IgG food sensitivity screen that looks at reactivity patterns across 96 commonly eaten foods. This guide explains what the test can show, what it does not diagnose, when it may be useful, and whether food intolerance testing, gut microbiome testing or a consultation is the better starting point.
What is a Food Intolerance Test and why would someone choose it?
A Food Intolerance Test is best thought of as a structured food reactivity screen. It looks at IgG patterns across commonly eaten foods and may help guide a measured elimination, rotation or reintroduction approach. It is not an IgE food allergy test, does not assess anaphylaxis risk, and should not be used as a permanent list of foods to avoid.
The kit is completed at home using the collection instructions supplied with your test.
Useful when you want a clearer starting point for elimination, rotation or reintroduction planning.
This is not an IgE allergy test and should not be used for acute reactions, hives, swelling or breathing symptoms.
The report is most useful when reviewed beside symptoms, current diet, restrictions and broader gut context.
For people who want food reactivity knowledge without making their diet unnecessarily restrictive.
Food intolerance testing may be considered when someone feels certain foods may not suit them and wants a more structured way to trial changes. It can be especially useful when the goal is to reduce guesswork without removing large food groups indefinitely.
- People who suspect delayed food reactions and want a clearer framework for food trials.
- Those who have already tried removing foods but want a more structured elimination and reintroduction approach.
- Clients wanting food reactivity information rather than a broad stool-based gut investigation.
- People who want help interpreting results without turning the report into an overly restrictive diet.
Food reactions can be easier to work with when you have a structured starting point.
Many people remove foods based on guesswork, online lists or short-term symptom changes. That can sometimes make eating feel more restrictive than it needs to be. Food intolerance testing can provide a clearer food reactivity map, but the results should be used carefully and in context.
- Instead of guessing: it gives a broad IgG reactivity map across commonly eaten foods.
- Instead of removing everything: it can help prioritise which foods are worth trialling first.
- Instead of avoiding foods forever: practitioner support can guide rotation, reintroduction and diet variety.
How Wellbeing George helps you use the information.
Understanding food reactivity patterns without overreacting
Food intolerance results are reviewed alongside symptoms, current diet, known allergies, gut symptoms, medications, supplements, stress and broader health history.
Turning a report into a realistic food plan
The goal is to help you understand what is worth trialling, what may not matter, and how to keep your diet as broad and nourishing as possible.
Choosing between food intolerance and gut testing
If bloating, bowel changes, abdominal discomfort or suspected gut imbalance are the main concerns, gut microbiome testing or SIBO testing may be a better starting point.
The Food Intolerance Test screens IgG reactivity across 96 commonly eaten foods.
The report includes a broad range of food categories. The value is not simply seeing a long list of foods. The value is knowing how to interpret the patterns and build a practical next step.
Grains and legumes: common staple foods and proteins often considered in food trial planning.
Dairy and egg: selected dairy proteins and egg components that may be relevant for elimination or rotation trials.
Fruits and vegetables: everyday plant foods that may appear in delayed food reactivity patterns.
Nuts and seeds: common exposures that may need careful interpretation, especially where allergies exist.
Meat, fish and shellfish: selected animal proteins and seafood items included in the broader panel.
Pantry foods and extras: selected herbs, spices, yeasts and other common dietary exposures.
Food Intolerance Test, Gut Microbiome Test or SIBO Breath Test?
These tests answer different questions. Choosing the right one depends on whether your main goal is food reactivity knowledge, broader stool-based gut ecology, or hydrogen and methane breath gas patterns.
A 96-food IgG reactivity screen when the main question is which foods may be worth trialling, rotating or reintroducing in a structured way.
It is not an IgE allergy test, not a gut microbiome test, and not a standalone diagnosis.
A stool-based view of selected gut microbiome, digestive, gut ecology and inflammation-related patterns.
It does not answer the same food IgG reactivity question as a food intolerance screen.
Hydrogen and methane breath gas patterns when bloating, gas or altered bowel habits suggest SIBO or methane-related patterns may be relevant.
It does not provide a broad food reactivity map or stool microbiome profile.
When food intolerance testing may be worth considering, and when it may not be the first step.
A good testing pathway is not about ordering the most popular test. It is about choosing the test that best matches your main question.
- May be worth considering: you want structured food reactivity information to guide a measured food trial.
- May be worth considering: you have already tried removing foods and want a clearer framework.
- May not be first choice: you have immediate reactions, hives, swelling, breathing symptoms or known food allergy concerns.
- May not be first choice: your main concern is persistent bloating, bowel changes, abdominal discomfort or suspected gut imbalance.
- Good middle step: start with a consultation if you are already eating a restricted diet or are unsure which test pathway fits best.

Free strategy chat
A short conversation to understand your main food or digestive concerns and whether food intolerance testing is likely to be useful.
Choose the right test
We help you consider whether food intolerance testing, gut microbiome testing, SIBO testing or a consultation first makes more sense.
Review the report in context
Results are interpreted alongside symptoms, current diet, known allergies, food history, medications, supplements and broader gut context.
Build your food plan
Recommendations may include a measured elimination, rotation or reintroduction plan, with food-first alternatives where appropriate.
Where food intolerance testing fits inside functional testing.
Food intolerance testing is a food reactivity screen. It may be useful on its own, but it can also be compared with gut microbiome testing, SIBO testing or a nutrition consultation depending on the main concern.
Not sure whether food intolerance testing is the right test for you?
A quick conversation can help you decide whether food intolerance testing, gut microbiome testing, SIBO testing, a bloodwork review or a nutrition consultation makes sense. You do not need to have it all worked out first.
Food Intolerance Test FAQs
What is the Food Intolerance Test?
The Food Intolerance Test is an IgG food reactivity screen that looks at patterns across 96 commonly eaten foods. It may help provide a more structured starting point for elimination, rotation or reintroduction planning.
Is this the same as a food allergy test?
No. This is not an immediate IgE food allergy test and it is not designed to assess anaphylaxis risk or acute allergic reactions. If you have immediate reactions, swelling, breathing symptoms, hives or a known allergy, speak with your GP, allergist or emergency care provider.
Who may benefit from food intolerance testing?
It may suit people wanting food reactivity knowledge, delayed reaction context or a clearer framework for food trials, especially when results are interpreted with symptoms, current diet and health history.
Should I choose this test or the Gut Microbiome Test?
If your main goal is food reactivity information, this test may be useful. If your main concern is ongoing bloating, gas, constipation, diarrhoea, abdominal discomfort, suspected dysbiosis or broader digestive issues, the Gut Microbiome Test may be a better starting point.
Does food intolerance testing diagnose disease?
No. Food intolerance testing through Wellbeing George is used for nutrition and wellness support. It is not designed to diagnose, treat or cure disease.
Should I order the test or book a consultation first?
If you already know you want the test, you can order it directly. If you are unsure, have multiple symptoms, are already restricting foods, or are deciding between food intolerance and gut testing, a free strategy chat or consultation can help you choose the right pathway.
