A food reactivity blood test measuring IgG antibodies to a wide range of commonly eaten foods to help guide a structured elimination and reintroduction programme.
£165
Results in 7–10 working days
Unlike IgE allergy testing, which looks for immediate allergic reactions, this test measures IgG antibodies to a wide range of foods. Some practitioners use IgG testing to help identify foods that may be associated with delayed symptoms such as bloating, abdominal discomfort, headaches or fatigue. The results should not be interpreted as diagnosing a food allergy or a food intolerance. Instead, they may be used as one piece of information alongside your medical history, symptoms and a carefully planned elimination and reintroduction diet. Your results are reviewed by one of our GPs, who will help you understand which findings may be worth exploring further and which should not result in unnecessary long-term dietary restriction.

Attend your appointment and one of our experienced nurses or phlebotomists will collect your blood sample. If your test also includes another sample, such as urine or stool, we will provide the necessary collection kit and clear instructions.
Results are typically available within 7–10 working days. Some individual markers may take longer if they require specialist laboratory processing. We will normally wait until the full profile is complete before issuing your reviewed results.
This test may be particularly useful for: Bloating; Irritable bowel symptoms; Food-related digestive symptoms; Unexplained gastrointestinal discomfort; Suspected delayed food reactions.
This test is commonly chosen when investigating: Bloating; Abdominal discomfort; Excess wind; Altered bowel habit; Feeling unwell after eating; Headaches that appear to relate to foods; Fatigue that may appear food related. Blood tests are only one part of an assessment, and results should be considered alongside your symptoms and medical history.
This test may help assess or investigate: Potential food reactivity patterns to commonly consumed foods (not food allergy diagnosis). An abnormal result does not necessarily confirm a diagnosis, but it may help guide further assessment.
This profile includes: Quantitative IgG antibody measurements to a broad panel of commonly consumed foods including dairy, eggs, cereals, meats, fish, shellfish, fruits, vegetables, legumes, nuts, seeds and selected herbs and spices (panel varies slightly depending on laboratory updates)..
