Overview of the Food Sensitivity Test with Interpretation Test
The Food Sensitivity Test with Interpretation is an at-home blood test measuring food-specific IgG responses across 220 food products.
The panel covers a broad range of commonly consumed and less common foods across fruit, dairy products, grains, legumes, meat, fish, seafood, nuts, seeds, spices, vegetables, mushrooms and other dietary ingredients.
The standard test uses a convenient finger-prick blood sample.
Your laboratory report includes the measured IgG responses together with interpretation and personalised recommendations.
Food-specific IgG is different from allergen-specific IgE.
IgG responses can reflect exposure to foods and immunological recognition of foods.
For that reason, food-specific IgG results should not be regarded as a stand-alone diagnosis of food allergy or food intolerance.
Results are best considered alongside your symptoms, dietary history and, where significant dietary changes are being considered, advice from an appropriately qualified healthcare or nutrition professional.
The Food Sensitivity Test with Interpretation costs £159.

Who May Benefit From the Food Sensitivity Test with Interpretation Test?
The Food Sensitivity Test with Interpretation may be useful for people who want to review food-specific IgG patterns as one part of a structured assessment of diet and symptoms.
People keeping a food and symptom diary - Laboratory information may provide an additional data point alongside observed dietary patterns.
People experiencing recurring digestive discomfort - Persistent symptoms should still be medically assessed where appropriate.
People considering a structured dietary review - Results can be discussed with a nutrition professional before making major restrictions.
People who want broad food coverage - The panel assesses 220 different food products.
People who prefer at-home sampling - The standard pathway uses a finger-prick blood sample.
People who want interpretation included - The report provides contextual information rather than laboratory values alone.
How to Prepare
Food-specific IgG can vary with dietary exposure.
Results should therefore be interpreted as laboratory information rather than a definitive diagnosis of intolerance.
Symptoms and Reasons to Consider the Food Sensitivity Test with Interpretation Test
Food-specific IgG testing does not diagnose the cause of symptoms, but some people choose testing while investigating recurring food-related patterns.
Bloating or digestive discomfort - These symptoms have many possible causes and should not automatically be attributed to food sensitivity.
Changes in bowel habit - Dietary patterns may be relevant, although persistent changes warrant appropriate clinical assessment.
Headaches occurring in relation to particular foods - A symptom diary can be useful alongside broader medical assessment.
Recurring skin concerns - Skin symptoms have numerous possible causes and IgG testing does not diagnose allergy.
Fatigue occurring alongside dietary concerns - Persistent fatigue may require investigation for anaemia, thyroid problems, nutritional deficiency or other causes.
Difficulty identifying patterns despite dietary tracking - Testing can provide additional information for discussion during a structured dietary review.
Food-specific IgG testing is not an IgE food allergy test.
Do not deliberately reintroduce a food that has previously caused swelling, breathing difficulty, collapse or another potentially serious allergic reaction simply to influence IgG results.

When Will I Receive My Results?
Results are generally available within approximately 5–10 days after the laboratory receives your sample.
Your report provides the measured food-specific IgG responses together with interpretation and personalised recommendations.
Sample quality or laboratory quality-control requirements can occasionally extend turnaround.
Understanding Your Results
The report shows the relative IgG response detected against the foods included in the panel.
A lower result indicates less measurable food-specific IgG for that food within the laboratory method.
A higher result indicates more measurable food-specific IgG.
This does not independently prove that the food is causing symptoms.
Food-specific IgG can be detected after normal dietary exposure and should not be interpreted as equivalent to IgE-mediated food allergy.
Any elimination or reintroduction plan should preserve adequate nutrition and should be approached particularly carefully where many foods appear reactive.
