Overview of the Dairy IgG Tolerance Panel
The Dairy IgG Tolerance Panel is a blood test that measures IgG antibody responses to dairy antigens included within the laboratory profile.
The test contains 1 laboratory biomarker profile: Dairy IgG Tolerance.
IgG antibodies are a normal part of the adaptive immune response and can develop following repeated exposure to food proteins.
This distinction is important because food-specific IgG is not the same as IgE-mediated food allergy.
More importantly, food-specific IgG testing is not considered a validated diagnostic method for food intolerance or food allergy by major allergy organisations.
Detectable or high food-specific IgG commonly reflects previous or repeated exposure to the food and may occur in people who tolerate that food normally.
The presence of dairy-specific IgG should therefore not be interpreted as proof that dairy is causing bloating, fatigue, headaches, skin symptoms or another complaint.
Likewise, a low IgG result does not prove that dairy cannot contribute to symptoms through another mechanism.
For example, lactose intolerance is caused by insufficient lactase activity and is not diagnosed by measuring dairy IgG.
Immediate reactions involving hives, swelling, wheezing or anaphylaxis require assessment for IgE-mediated allergy, not an IgG tolerance panel.
This test is best regarded as a laboratory measurement of dairy-specific IgG response, with its clinical limitations clearly understood before testing.
What Does the Dairy IgG Tolerance Panel Test Check?
This test measures 1 laboratory profile.
Dairy IgG Tolerance
Measures IgG antibody response to dairy antigens included within the laboratory panel. Food-specific IgG usually reflects immune exposure and is not a validated standalone test for diagnosing food allergy or food intolerance.
Who May Benefit From the Dairy IgG Tolerance Panel Test?
Because food-specific IgG is not a validated diagnostic marker of food intolerance, this panel should be considered only with a clear understanding of its limitations.
People specifically advised to obtain a dairy IgG laboratory profile - The test may provide the requested laboratory measurement where a healthcare professional has explained its limitations.
People who want to document dairy-specific IgG exposure - The result shows an IgG response but should not be interpreted as proof of intolerance.
People comparing previous food-specific IgG results - Repeat testing may provide laboratory comparison, although changes do not necessarily correspond with symptoms.
People undertaking clinician-supervised nutritional investigation - An IgG result may occasionally be reviewed alongside a much broader dietary assessment, provided it is not treated as a diagnostic result.
People with persistent gastrointestinal symptoms who have already considered validated causes - Symptoms such as bloating or diarrhoea may require evaluation for lactose intolerance, coeliac disease, inflammatory bowel disease or other conditions rather than relying on IgG.
People unsure whether their symptoms represent allergy or intolerance - The distinction can be clarified clinically before choosing the appropriate test.
People with immediate dairy reactions - These individuals should generally consider IgE-mediated allergy assessment instead of using an IgG result to evaluate allergy.
People considering major dietary restriction - Testing should ideally be accompanied by professional nutritional advice so that unnecessary exclusion of calcium, protein and other nutrients is avoided.
How to Prepare
Food-specific IgG results should not be used as a standalone basis for restrictive diets.
Where dairy causes reproducible symptoms, the next investigation should depend on the symptom pattern: lactose intolerance testing for non-immune digestive symptoms, or IgE allergy assessment for immediate allergic reactions.
Symptoms and Reasons to Consider the Dairy IgG Tolerance Panel Test
The following symptoms are commonly attributed to foods by patients, but none can be diagnosed as dairy intolerance using food-specific IgG alone.
Bloating - Dairy-related bloating can occur with lactose intolerance, but IgG measurement does not diagnose lactase deficiency.
Abdominal discomfort - Gastrointestinal symptoms have many potential causes and should not automatically be attributed to a food-specific IgG result.
Diarrhoea - Lactose malabsorption is one possible cause, but infection, coeliac disease, inflammatory bowel disease and functional bowel disorders are also possibilities.
Constipation - Constipation is non-specific and cannot be linked to dairy on the basis of an IgG result.
Headaches - Headaches have numerous causes, and food-specific IgG does not establish dietary causation.
Fatigue - Tiredness should not be attributed to dairy simply because dairy-specific IgG is detectable.
Skin symptoms - Eczema and other skin disorders may coexist with food sensitisation, but IgG does not diagnose food allergy.
Symptoms that appear to follow dairy consumption - A structured dietary history, validated testing and supervised elimination/reintroduction may be more informative than IgG alone.
Food-specific IgG is commonly found in healthy people who regularly eat the corresponding food.
A high result should therefore not be interpreted as evidence that dairy is damaging the body or causing inflammation.
Immediate swelling, hives, wheezing, breathing difficulty or anaphylaxis after dairy exposure requires IgE-focused allergy assessment and, during an active severe reaction, emergency treatment.
How to Book Your Dairy IgG Tolerance Panel Test
Booking the Dairy IgG Tolerance Panel with London Blood Tests is straightforward, but its diagnostic limitations should be understood before testing.
Choose the Dairy IgG Tolerance Panel
Select the panel and review that it measures dairy-specific IgG rather than diagnosing IgE allergy or lactose intolerance.
Select your sample collection option
Choose an in-clinic blood draw (+£35) or a home or hotel phlebotomy visit (+£60).
Attend your appointment
A trained professional collects the required venous blood sample.
Laboratory analysis
Your serum is analysed for the dairy-specific IgG response included within the laboratory profile.
Receive your results securely
Your authorised result is delivered securely and can be discussed with a GP, dietitian or other suitably qualified healthcare professional.
When Will I Receive My Results?
The expected turnaround time for the Dairy IgG Tolerance Panel is approximately 2 business days after your sample reaches the laboratory.
Results are released after laboratory analysis and authorisation.
Understanding Your Results
A lower IgG result means relatively little IgG reactivity was detected to the dairy antigens measured by the assay.
This does not prove that dairy is tolerated and does not rule out lactose intolerance or IgE-mediated allergy.
A higher dairy-specific IgG result indicates a measurable immune response following exposure to dairy proteins.
Importantly, this finding is not considered evidence of dairy intolerance or allergy.
Food-specific IgG antibodies are frequently found in healthy people and can represent normal immune recognition following repeated food exposure.
Major allergy organisations advise against using food-specific IgG or IgG4 testing to diagnose food hypersensitivity.
For that reason, an elevated result should not automatically lead to dairy elimination.
If symptoms clearly occur after dairy, the clinical pattern should guide further investigation.
Immediate hives, swelling or breathing symptoms suggest an IgE-mediated mechanism, whereas bloating, gas and diarrhoea may be more compatible with lactose malabsorption or another gastrointestinal condition.

Private Dairy IgG Tolerance Panel Blood Test in London
London Blood Tests provides the Dairy IgG Tolerance Panel in London for people who specifically wish to measure their dairy-specific IgG response.
The panel costs £219 and contains one laboratory profile: Dairy IgG Tolerance.
The test should not be described as a definitive dairy intolerance test.
Current allergy guidance does not support food-specific IgG as a diagnostic marker of food allergy or food intolerance.
People experiencing symptoms after dairy may require a different investigation depending on whether the suspected mechanism is IgE-mediated allergy, lactose intolerance or another gastrointestinal condition.
Results are expected approximately 2 business days after the laboratory receives the sample.
