Unexplained bloating, diarrhoea, fatigue, or nutrient deficiencies may signal coeliac disease. The Tissue Transglutaminase IgA Blood Test checks for IgA antibodies that attack the small intestine in response to gluten, making it one of the most reliable markers for coeliac disease.

Why the Tissue Transglutaminase (IgA) Test Matters?

Detecting Tissue Transglutaminase IGA levels helps identify autoimmune activity against gluten. This test is widely used to screen for coeliac disease, allowing for earlier diagnosis and treatment, such as a gluten-free diet. Understanding your tissue transglutaminase IGA normal range is crucial in ensuring a timely and accurate diagnosis, giving you peace of mind and an effective management plan.

FAQs

What does the Tissue Transglutaminase (tTG IgA) Test measure?

The tTG IgA test measures IgA antibodies against tissue transglutaminase, an enzyme targeted in coeliac disease. Elevated levels indicate an autoimmune reaction to gluten.

Who should consider this coeliac disease test?

This test is recommended for individuals with persistent digestive problems, malabsorption, nutrient deficiencies, unexplained fatigue, skin rashes, or a family history of coeliac disease.

How is the sample collected?

The test requires a simple venous blood draw, which is then analysed in a laboratory to check for tTG IgA antibodies.

What do positive Tissue Transglutaminase IgA results mean?

A positive result strongly suggests coeliac disease or gluten intolerance. However, additional tests, such as an intestinal biopsy, may be recommended to confirm the diagnosis.

Can a gluten-free diet affect test results?

Yes. Starting a gluten-free diet before testing can lower antibody levels, leading to false negatives. For accurate results, you should continue eating gluten until after the test.
