Wheat Allergy Testing
View All TestsWhat Is Wheat Allergy?
Wheat allergy is an IgE-mediated food allergy to proteins found in wheat. It can cause symptoms ranging from mild oral or skin reactions to exercise-induced anaphylaxis (wheat-dependent exercise-induced anaphylaxis, or WDEIA), which is specifically linked to the omega-5 gliadin component.
Wheat allergy is distinct from coeliac disease (an autoimmune condition triggered by gluten) and from non-coeliac gluten sensitivity (food intolerance). IgE blood testing specifically investigates the allergic mechanism.
Component testing for omega-5 gliadin is particularly important as it is the key marker for WDEIA. Results should be shared with your GP or allergist for interpretation.

Frequently Asked Questions
What is wheat-dependent exercise-induced anaphylaxis?
WDEIA is a condition where eating wheat followed by exercise can trigger anaphylaxis. It is specifically associated with the omega-5 gliadin protein. The reaction does not occur with wheat alone or exercise alone — only when combined. Testing for omega-5 gliadin IgE is an important diagnostic step.
Is wheat allergy the same as coeliac disease?
No. Wheat allergy is IgE-mediated and causes immediate-type allergic reactions. Coeliac disease is an autoimmune condition triggered by gluten that damages the small intestine. The mechanisms, testing, and management are entirely different.
Do I need a GP referral for allergy testing?
No. You can book directly with our clinic without a GP referral. Simply choose your test and select a convenient appointment time. If you're unsure which test is right for your symptoms, our team can help guide your selection.
Do I need to stop taking antihistamines before a blood test?
No. Unlike skin prick testing, IgE blood tests are not affected by antihistamines or other allergy medications. You can continue taking your regular medications before your appointment.
What should I do with my results?
As a diagnostic-only clinic, we provide results directly to you. We recommend sharing them with your GP or allergist for interpretation and to discuss dietary management.
