Items tested


  • Transglutaminase IgA – gluten sensitivity marker

The tissue transglutaminase IgA test is the most sensitive and effective method of celiac disease testing.

It shows positive results in almost 98% of people with celiac disease who eat gluten.

How It Works


Faecal anti-tissue transglutaminase IgA antibodies indicate a reaction of the immune system to the tissue transglutaminase enzyme produced by the body when gluten is ingested, leading to an autoimmune reaction that may destroy the intestinal lining or other tissues in the body.

Stool analysis for antibodies against gluten-related antigens has been found be a more sensitive assessment to gluten/immune reactions than blood tests. 


Positive faecal anti-tissue transglutaminase IgA (produced in situ by the gut lining) result from a specific immune reaction to gluten in the digestive tract, and may not show in blood, especially in the absence of the typical coeliac disease-related damage to the intestinal tract (i.e., villous atrophy).

If you prefer a blood test for your client, we can order this for you.
