Retesting following a negative test

It’s possible to have a negative blood test and still have coeliac disease. If you weren't eating gluten at the time of your blood test, or you had limited your gluten intake, you may have received an inaccurate result.

If you have removed gluten from your diet, you will need to reintroduce gluten before being retested. This is normally referred to as the gluten challenge. However, before taking this step you should discuss it with your GP. If you have ongoing symptoms that suggest coeliac disease but have had a negative blood test, and you were eating gluten at the time of the test, ask your GP to check to see if you have been tested for IgA deficiency.

Our online assessment is designed for those individuals who have symptoms associated with coeliac disease and who have not previously been tested for coeliac disease. If you have been tested but are continuing to experience symptoms, you should talk to your GP about the need for further testing.
