Coeliac Check Plus

About this test

Coeliac disease is an autoimmune condition caused by sensitivity to gluten. It can start at any age, but most people are diagnosed in adulthood. Once you have coeliac disease you will have it for life. Exposure to gluten causes inflammation in the lining of the small intestine causing discomfort, bloating and diarrhoea, and preventing food and nutrients from being digested effectively. Coeliac disease is common, affecting approximately 1 in 100 people. However, this rises to 1 in 10 people if a close family member has coeliac disease or if you already suffer from an autoimmune disease. It is controlled by eliminating gluten from the diet.

It is important to eat gluten with each meal for 6 weeks prior to this test. This maximises the chance of detecting coeliac disease on the test. If this advice isn’t followed then there is a danger of coeliac disease being missed by the test. 

The laboratory may perform more than one coeliac antibody test if they suspect that Immunoglobulin A (IgA) Deficiency may be causing a false negative result. Immunoglobulin A Deficiency is the most common immune system deficiency in the United Kingdom, and besides making it more likely that an individual catches coughs and colds, can also cause IgA based coeliac testing to fail. Our laboratory will recognise when IgA deficiency is likely and perform the extra tests needed to confirm whether coeliac disease is likely at no extra cost.

Who is this test for?

This blood test is for individuals who are suffering digestive problems which they think might be caused by gluten sensitivity. The results can help to distinguish between Coeliac Disease, and Non-Coeliac Gluten Sensitivity

Tests Included

Coeliac Status

Tissue Transglutaminase (tTG) IgA is an autoantibody produced in the immune response seen in Coeliac disease.

Coeliac disease is an autoimmune condition caused by a sensitivity to gluten. It can start at any age, but most people are diagnosed in adulthood. Once you have coeliac disease you will have it for life. Exposure to gluten causes inflammation in the lining of the small intestine causing pain and irritation, preventing food and nutrients from being digested effectively. 

A negative result does not necessarily exclude Coeliac disease. If you are symptomatic you may require further testing.
