Details about Allergy & Food Sensitivity Test Bundle
What Is a Food Allergy & Sensitivity Test Bundle?
A food allergy and food sensitivity test bundle combines different types of blood testing to assess how your immune system reacts to food.
This typically includes:
- IgE testing → identifies immediate allergic reactions
- IgG testing → explores delayed immune responses or sensitivities
These are two completely different biological mechanisms — and combining them gives a broader picture of how your body responds to food.
Food Allergy vs Food Sensitivity – Key Difference
Understanding this is critical (and most clinics get this wrong).
Food Allergy (IgE-mediated)
- Immediate reaction (minutes to hours)
- Can be severe or life-threatening
- Symptoms:
- Swelling, hives
- Breathing issues
- Anaphylaxis
- Swelling, hives
- Breathing issues
- Anaphylaxis
IgE antibodies are directly involved in allergic reactions and are the clinical standard for allergy testing
Food Sensitivity (Non-IgE / IgG-related)
- Delayed reaction (hours to days)
- Symptoms can include:
- Bloating
- Fatigue
- Brain fog
- Skin issues
- Bloating
- Fatigue
- Brain fog
- Skin issues
However — and this is important:
- IgG antibodies often reflect exposure, not intolerance
- Many medical organisations do not consider IgG tests diagnostic
👉 Translation:
IgG testing is best used as a guidance tool, not a diagnosis.
Why Combine IgE + IgG Testing?
Most providers only offer one — which is incomplete.
This bundle gives:
- Immediate allergy detection (IgE)
- Pattern-based sensitivity insights (IgG)
- A more holistic view of food reactions
This is especially useful if you experience:
- Ongoing digestive issues
- Skin conditions (acne, eczema)
- Fatigue or inflammation
- Unexplained symptoms after eating
What we test
The panel analyses immune responses across multiple food and environmental categories.
Food Sensitivities (220 foods - IgG)
Includes a broad range of foods such as:
Fruits & Berries
Apple, banana, orange, mango, kiwi, pineapple, peach, pear, berries and more.
Grains & Cereals
Wheat, barley, rye, oats and other grains.
Dairy & Eggs
Milk proteins, cheese, yogurt, egg white and yolk.
Meat & Fish
Chicken, beef, pork, tuna, salmon and seafood varieties.
Vegetables & Legumes
Tomato, potato, soy, beans and other plant foods.
Nuts & Seeds
Almond, peanut, hazelnut, sesame and others.
Other Dietary Components
Yeast, coffee, cocoa/chocolate and additional dietary items.
The test covers both common and less common foods encountered in everyday diets.
Allergens (98 allergens - IgE)
Includes environmental and food allergens such as:
• Tree, grass and weed pollens
• House dust mites
• Animal dander (cat, dog, horse)
• Moulds and fungi
• Inhalant allergens
• Selected food allergens
These represent the most common triggers in the population.
Who Should Consider This Test?
This test is ideal if you:
- Suspect food allergies or reactions
- Experience bloating, IBS-like symptoms, or gut issues
- Have skin conditions (acne, eczema, inflammation)
- Feel fatigued after eating
- Want to optimise diet for performance or longevity
It is also commonly used in:
- Functional medicine protocols
- Elimination diets
- Gut health optimisation
Important Clinical Context (What Most Clinics Won’t Tell You)
Let’s be clear:
- IgE testing → clinically validated for allergies
- IgG testing → not a confirmed diagnostic tool
Research shows that IgG antibodies may simply reflect regular exposure or tolerance to foods, not intolerance
👉 That means:
- A “high” result does not automatically mean you must avoid that food
- Results should be used alongside symptoms, not blindly followed
How to Use Your Results Properly
The correct approach is:
1. Identify patterns (not single foods)
2. Remove suspected triggers temporarily
3. Reintroduce foods systematically
4. Track symptoms objectively
This avoids:
- Unnecessary food restrictions
- Nutritional deficiencies
- Misinterpretation of results

Follow these guidelines for accurate results
Sample Timing
Where possible, attend your blood test between 7am and 12pm. Please wait until any short-term illness or infection has fully resolved before testing. Avoid intense exercise for 24–48 hours beforehand, as this can affect certain markers.
Fasting & Hydration
Fasting is not always required, but some tests may recommend it. If fasting is advised, avoid food for 8–12 hours before your appointment and drink water only. Stay well hydrated, as this helps with sample collection and accuracy.
Medications & Supplements
Continue prescribed medications unless advised otherwise by your clinician. Avoid vitamin, mineral, or biotin supplements for at least 24–48 hours before your test, as these can interfere with results. If you are unsure about any medication or supplement, please let us know before your appointment.
Hormones & Menstrual Cycle
For hormone-related tests, timing within your menstrual cycle may be important. If relevant, follow any specific guidance provided on your test page.
If you have any questions or special circumstances, our team is happy to advise before your appointment.
Frequently Asked Questions
Results are typically delivered in around 5–10 days after the lab receives your sample.
No fasting is required for either the allergy (IgE) or food sensitivity (IgG) portion — just collect the sample as instructed.
Yes, this type of antibody testing can be used for children, but results should be interpreted with paediatric guidance.
The IgE component identifies allergic sensitisation, but a clinical allergy diagnosis should be confirmed with a healthcare professional.
IgE shows true allergic reactions, while IgG suggests a delayed immune response linked to food sensitivities rather than classic allergy.
Yes — no specific dietary restrictions are needed before the finger-prick sample.
Your personalised report includes guidance; many people start with an elimination approach followed by symptom tracking.
Usually not — this is a private, at-home blood test.
Yes — your results are delivered securely and remain confidential between you and the testing laboratory.
Yes, many people retest after dietary changes or after several months to track progress.
