Wimpole Street, Marylebone
Within the coeliac disease and gluten range at Wimpole Street, the Gluten Sensitivity Evaluation is the test to consider when the question concerns celiac Disease, wheat Allergy and digestive System. It costs £195, and once the Marylebone clinic opens on 1 October 2026 a nurse or phlebotomist takes the venous blood sample (serum), with the laboratory typically reporting in 2 days. Medical services are for patients aged 16 and over, self-referral with no GP referral needed, and the laboratory report is delivered to your secure portal.

Preparing for your Gluten Sensitivity Evaluation
- 1Keep eating gluten — bread, pasta, cereals — daily for at least six weeks before the blood test; a gluten-free diet lowers the antibodies and can produce a false negative.
- 2No fasting is needed for serology or the HLA gene test.
- 3If you have already gone gluten-free and cannot face reintroducing it, the HLA test can still be useful, as a negative result makes coeliac disease very unlikely.
Sample for this test: venous blood sample (serum).
What Gluten Sensitivity Evaluation measures
The catalogue tags the Gluten Sensitivity Evaluation with celiac Disease, wheat Allergy and digestive System. Those terms describe the territory the test covers; the notes below explain what a coeliac disease and gluten result can and cannot tell you.
Coeliac serology measures tissue transglutaminase IgA (tTG-IgA), the primary antibody produced when gluten damages the small bowel lining, alongside total IgA to make sure the test is valid; tTG-IgG and deamidated gliadin antibodies are used where IgA is low. HLA DQ2/DQ8 genotyping identifies whether you carry the genes that make coeliac disease possible — almost everyone with the condition has one of them, but so does a third of the general population. Gluten sensitivity profiles combine serology with genetics and nutritional markers.
Who considers Gluten Sensitivity Evaluation
- People often consider coeliac testing if they have bloating, loose stools, wind or abdominal pain that comes and goes.
- Unexplained iron, B12 or folate deficiency, or osteoporosis at a young age, are common prompts.
- A first-degree relative with coeliac disease raises the likelihood roughly tenfold and is a recognised reason to test.
- Those with type 1 diabetes or autoimmune thyroid disease frequently check, as the conditions cluster.
- An itchy blistering rash on the elbows, knees or buttocks may lead to testing for the skin form of the condition.
Understanding your Gluten Sensitivity Evaluation results
A clearly raised tTG-IgA, particularly at more than ten times the upper limit, can indicate coeliac disease with high probability; in adults, confirmation by small-bowel biopsy is still usually recommended before committing to a lifelong diet. A negative tTG with a normal total IgA makes active coeliac disease unlikely provided gluten was being eaten. A negative HLA DQ2/DQ8 result effectively excludes the condition, whereas a positive one only shows susceptibility.
Coeliac serology is only reliable while gluten is in the diet, and a result is interpreted alongside symptoms, nutritional markers and, where needed, biopsy.
