What is a Food Intolerance Test?
A Food Intolerance Test is a method used to identify foods that may be causing non-allergic adverse reactions in your body. Unlike a food allergy, which involves a rapid and potentially life-threatening immune system response, a food intolerance primarily affects your digestive system, with symptoms often appearing hours or days after eating the trigger food.
The test uses a blood sample (serum) to measure immunoglobulin G (IgG) antibodies against various foods. This test helps detect delayed hypersensitivity reactions that may be contributing to your chronic health conditions and discomfort.
What does the Food Intolerance Test measure?
This test measures specific markers that help identify problematic foods in your diet:
• IgG Antibodies: Detects Immunoglobulin G antibodies produced when your immune system reacts to specific foods
• Delayed Hypersensitivity Reactions: Identifies type III delayed onset reactions that occur hours or days after consuming trigger foods
• Food-Related Inflammation: Measures immune responses that may contribute to chronic inflammation in your body
• Dietary Triggers: Pinpoints specific foods that may be causing ongoing health symptoms
• Comprehensive Food Panel: Tests reactions to 215 different food items including proteins, grains, fruits, vegetables, and spices
Food Intolerance Test: Who Needs It and Why It's Done
What Symptoms May Call for a Food Intolerance Test?
Your doctor may recommend this test if you experience persistent symptoms that seem related to your diet:
• Chronic bloating and digestive discomfort
• Frequent headaches or migraines
• Persistent fatigue and low energy levels
• Skin problems like eczema or unexplained rashes
• Digestive issues including diarrhoea or constipation
• Joint pain and inflammation
• Brain fog and difficulty concentrating
• Mood changes or irritability after eating
• Recurring nausea or stomach pain
• Autoimmune symptoms like thyroiditis, psoriasis, or lupus exacerbations possibly linked to diet.
Who should get a Food Intolerance Test?
This test is particularly helpful for specific groups of people experiencing ongoing health concerns:
• Patients with persistent symptoms experiencing chronic digestive issues without a clear diagnosis
• People with autoimmune conditions where diet may play a role in inflammation
• Patients with irritable bowel syndrome seeking dietary management options
• Individuals with persistent fatigue that might be linked to food sensitivities
• Individuals with suspected food sensitivities who notice symptoms after eating certain foods
• Patients evaluated by doctors who have ruled out food allergies and other conditions
Why is a Food Intolerance Test done?
A Food Intolerance Test helps create a personalised dietary plan by identifying specific foods that trigger your symptoms. This enables you to make informed choices about what to eat, potentially reducing chronic inflammation and improving your overall quality of life.
Importance of a Food Intolerance Test
Understanding your food intolerances is crucial for managing chronic health conditions that may be diet-related. This test provides valuable insights into which foods might be contributing to ongoing symptoms like digestive problems, headaches, or fatigue. By identifying trigger foods, you can work with healthcare professionals to develop a tailored elimination diet that may significantly improve your symptoms.
The comprehensive nature of this test ensures that even less obvious triggers are identified. This information supports better dietary choices and can help reduce inflammation, improve digestion, and enhance your overall well-being.

• Gut health conditions like leaky gut syndrome may cause elevated reactions to multiple foods
• Dehydration can concentrate blood components, potentially affecting antibody measurements
• Recent illness or infections may temporarily alter your immune system's response patterns
• Sample quality issues such as haemolysis or improper storage can compromise results
• Timing of food consumption relative to antibody production cycles may influence readings
