About the Test
The Tissue Transglutaminase Antibody, IgA test is one of the main blood tests used to screen for coeliac disease, an immune reaction to gluten that damages the small intestine. It measures IgA antibodies against tissue transglutaminase, which rise when someone with coeliac disease eats gluten. It is typically ordered for digestive symptoms, unexplained iron deficiency, or a family history of coeliac disease. For the result to be reliable you should still be eating gluten, because a gluten-free diet can lower the antibody and mask the condition.
What is it? A blood test measuring IgA antibodies against tissue transglutaminase, also known as tTG, anti-tTG or the coeliac antibody test.

Tissue Transglutaminase Antibody, IGA test: purpose, preparation and results
Why take the Tissue Transglutaminase Antibody, IGA test?
- Digestive symptoms such as bloating, diarrhoea, abdominal pain or weight loss suggest possible coeliac disease
- Unexplained iron-deficiency anaemia, fatigue or nutrient deficiencies need investigating
- A close family history of coeliac disease or a related autoimmune condition prompts screening
How to prepare for the Tissue Transglutaminase Antibody, IGA test
No fasting is needed. Importantly, keep eating your normal gluten-containing diet before the test, as cutting out gluten can lower the antibody and lead to a falsely normal result. Tell your doctor if you have already reduced gluten.
Understanding your Tissue Transglutaminase Antibody, IGA results
A raised tTG-IgA result suggests coeliac disease and usually leads to confirmatory testing, often an intestinal biopsy, while a normal result makes it less likely if you were still eating gluten. Low total IgA can affect the test, so a doctor interprets it in full context. Your doctor-reviewed report is ready in 7 Days.

Your report is typically ready in 7 Days after collection, then reviewed by a doctor before it reaches you on WhatsApp and email. The specialised antibody assay is the reason it takes longer than a standard blood test.
No, keep eating gluten as normal. A gluten-free diet lowers tissue transglutaminase antibodies and can produce a falsely normal result, which may hide coeliac disease. If you have already cut back on gluten, tell your doctor so the result is interpreted correctly.
Not on its own. A positive tTG-IgA strongly suggests coeliac disease, but doctors usually confirm it with further testing such as an intestinal biopsy. Your report should be reviewed by a doctor who will advise on the next step.
No fasting is required. You can eat and drink normally, and you should continue your usual gluten-containing diet. The only preparation that matters here is not removing gluten before testing.
