What is a Food Intolerance Test?
A food intolerance test is a blood test that measures immunoglobulin G (IgG) antibodies your body produces in response to specific foods. It is different from a food allergy test, which measures IgE antibodies and relates to potentially severe, immune-mediated reactions. Doctors may order this test when a patient experiences persistent digestive symptoms or other discomforts that appear linked to diet. The test is also called the Food sensitivity test, IgG food test, or Food IgG panel.
What Does a Food Intolerance Test Measure?
The food intolerance test procedure analyses food-specific IgG antibodies in your blood serum. The panel can screen antibody responses to a wide range of food groups. Here are the main categories typically covered:
- Dairy products (milk, cheese, yoghurt)
- Grains and cereals (wheat, gluten, rice)
- Eggs (white and yolk)
- Seafood (fish and shellfish)
- Fruits and vegetables
- Nuts and legumes
- Meats (chicken, beef, pork)
- Spices and food additives
Elevated IgG antibody levels against a particular food may suggest the body is reacting to it, which your doctor can review alongside your symptoms and medical history.
Why is a Food Intolerance Test Done?
This test is ordered when a person has ongoing symptoms that may be connected to specific foods in their diet.
Common Symptoms That May Require This Test
The following symptoms are among the most common reasons a doctor may suggest a food intolerance test:
- Bloating and abdominal discomfort
- Diarrhoea or constipation
- Stomach cramps
- Persistent headaches
- Fatigue or low energy
- Nausea
- Skin rashes or joint pain
Conditions This Test Can Help Detect
This test can help identify potential food triggers for several conditions. These include:
- Lactose intolerance (difficulty digesting milk sugar)
- Gluten intolerance (sensitivity to gluten found in wheat-based foods)
- Histamine intolerance (reactions to foods like wine and aged cheese)
- Caffeine sensitivity
- Reactions to food additives such as sulphites and preservatives
- Irritable bowel syndrome (IBS) with suspected dietary triggers
- Chronic digestive discomfort of unknown cause
How to Prepare and What to Expect
Preparing for a food intolerance test is straightforward and requires minimal effort on your part.
Do You Need to Fast?
No fasting is required for this test. You can eat and drink normally on the day of sample collection. Continue eating your usual diet, including any foods you suspect may be causing symptoms, in the days leading up to the test.
Practical Tips Before Your Test
The following steps will help your sample collection go smoothly:
- Bring a detailed clinical history, including your symptoms, previous test results, and any relevant medical records, as this is required for the test
- Inform your doctor about any medications or supplements you are currently taking, as these may affect results
- Drink plenty of water before your appointment for an easier blood draw
- Wear comfortable clothing with sleeves that can be rolled up easily
- Continue your normal diet before testing
Step-by-Step Procedure
Here is what to expect during sample collection:
- A trained phlebotomist (a specialist in blood collection) cleans the skin on your inner arm with an antiseptic solution.
- An elastic band is placed around your upper arm to make your veins easier to access.
- A small needle is inserted into the vein. You may feel a brief pinch. Blood is drawn into a labelled collection tube in under a minute.
- The needle is removed, and a small cotton swab and bandage are applied to the site. You can return to normal activities right away.
- The serum sample is stored under refrigeration and dispatched to the laboratory, where it is tested using EIA (enzyme immunoassay) methodology.
- Your report is prepared and delivered within three days.
Factors That Can Affect Accuracy
Several factors can influence your test results. These include:
- Poor hydration before sample collection
- Recent infections, which can raise overall IgG levels
- Immunosressive medications or steroid therapy, which may lower antibody levels
- Improper sample handling or storage
- Not disclosing current medications to your doctor
Understanding Your Food Intolerance Test Results
Your results will show IgG antibody levels against each food tested. A doctor should always review these results alongside your symptoms, diet history, and overall health. The table below shows general reference ranges:
| Parameter | Range | Interpretation |
|---|---|---|
| Food-Specific IgG | Less than 50 U/mL | Negative, no significant reaction detected |
| Food-Specific IgG | 50 U/mL or above | Positive, potential sensitivity to that food |
These ranges are general guidelines. Your doctor will interpret your results based on your age, health history, and other factors. Always consult a qualified healthcare professional for personalised medical advice.
It is also important to note that several major medical organisations, including allergy and immunology bodies, have stated that IgG testing alone should not be used to diagnose food intolerance without clinical correlation. A positive result does not confirm a diagnosis on its own.
Results During Special Conditions
Certain situations can affect how results should be interpreted. A recent infection can raise overall IgG levels in the blood, which may affect individual food-specific readings. Patients on immunosuppressive therapy may show lower antibody levels, potentially underrepresenting any sensitivities.
How to Maintain Healthy Levels
The following general wellness practices are worth considering:
- Maintain a varied, balanced diet unless specific intolerances are confirmed through proper medical evaluation
- Keep a food and symptom diary to help identify patterns before making any dietary changes
- Do not remove food groups from your diet without guidance from a doctor or qualified dietitian, as this may lead to nutritional gaps

Frequently Asked Questions
A food allergy involves an immune response that can affect the whole body and, in severe cases, can be life-threatening. Food intolerance does not involve the same immune pathway and is generally not life-threatening. Symptoms of intolerance are usually confined to digestion, though they can affect other systems. A doctor can help determine which condition applies to you.
Symptoms of food intolerance usually appear a few hours after eating the trigger food. In some cases, symptoms may take up to three days to develop and can persist for several weeks. This delayed onset is one reason it can be difficult to identify trigger foods without a structured test or food diary.
No fasting is required. You can eat and drink normally before your sample collection. In fact, continuing to eat your usual diet before the test, including suspected trigger foods, is generally recommended.
Several major allergy and immunology organisations have noted that IgG testing alone does not reliably diagnose food intolerance, and that positive IgG results can be found in healthy individuals with no symptoms. These tests are best used as one part of a broader clinical evaluation rather than as a standalone diagnostic tool. Always discuss your results with a qualified healthcare professional.
A positive result means elevated IgG antibodies were found against a particular food. This does not automatically confirm an intolerance. Consult a doctor, allergist, or gastroenterologist to review your results in the context of your symptoms. A registered dietitian can also help you manage any dietary changes safely.
Yes. It is possible to develop a food intolerance at any age, including to foods you have eaten regularly for years without any problems. Changes in gut health, medications, or other health conditions can sometimes trigger new sensitivities. If you notice new digestive or other symptoms, speak to your doctor.
A small venous blood sample is drawn from a vein in your arm by a trained phlebotomist. The process takes less than a minute. The serum is separated from the blood and sent to the laboratory for IgG antibody analysis. You can return to your normal activities immediately after collection.
