Dairy IgG Tolerance Panel
The Dairy IgG Tolerance Panel measures IgG antibodies to common dairy foods. It helps identify delayed food sensitivities that may contribute to digestive and systemic symptoms.

Details about Dairy IgG Tolerance Panel
What is the Dairy IgG Tolerance Panel?
The Dairy IgG Tolerance Panel is a blood test that measures Immunoglobulin G (IgG) antibodies produced in response to specific dairy proteins. Unlike immediate food allergies, IgG reactions are delayed and may cause symptoms hours or even days after consumption.
This panel focuses specifically on dairy-related foods, helping to identify sensitivities to common components such as milk proteins and lactose-containing products. It is frequently used in functional and integrative medicine to support dietary optimisation and symptom investigation.
IgG testing does not diagnose food allergy but provides insight into how the immune system responds to repeated exposure to certain foods.
Why do I need a Dairy IgG Tolerance Panel?
Dairy sensitivity is a common but often overlooked cause of chronic digestive and inflammatory symptoms. Because IgG reactions are delayed, many people do not associate their symptoms with dairy consumption.
This test is useful when symptoms persist despite normal allergy testing or routine investigations.
You may benefit from this test if you experience:
- Bloating or abdominal discomfort
- Diarrhoea or constipation
- Fatigue or low energy
- Brain fog or poor concentration
- Headaches or migraines
- Skin issues such as acne or eczema
- Sinus congestion
- Joint or muscle aches
Identifying dairy-related IgG reactions can support targeted elimination diets and long-term symptom management.
Benefits of the Dairy IgG Tolerance Panel
- Identifies delayed dairy sensitivities
Detects immune reactions not picked up by allergy tests. - Supports digestive health assessment
Useful for unexplained bloating or bowel symptoms. - Helps personalise dietary choices
Guides elimination or reduction strategies. - May reduce chronic inflammation triggers
Supports symptom improvement through diet. - Non-invasive and simple
Requires only a blood sample. - Useful when allergy tests are negative
Investigates non-allergic immune responses. - Supports gut health optimisation
Often used alongside microbiome or gut testing. - Improves symptom awareness
Helps link food intake with delayed reactions.
Step by step – how the test works
You can access testing UK-wide through two options:
- Clinic appointment
Choose your nearest UK clinic. A healthcare professional will collect your blood sample. - At-home or hotel visit (£60 extra)
A qualified phlebotomist visits your home or hotel, so you don’t need to travel.
Your sample is analysed in a UK laboratory, and results are provided securely.
Your results explained
Low IgG levels (Negative reaction)
Suggest no significant immune response to the tested dairy foods. These foods are generally well tolerated.
Typical UK interpretation:
- Low or absent IgG antibodies
Moderate IgG levels
Indicate a possible sensitivity. Symptoms may occur with frequent or large amounts of the food.
Typical UK interpretation:
- Mild to moderate IgG elevation
High IgG levels
Suggest a strong immune response to specific dairy proteins. These foods may contribute to symptoms and are often recommended for temporary elimination.
Typical UK interpretation:
- High IgG antibody levels above laboratory thresholds
Exact values and grading depend on laboratory methodology.

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.
