Have the tTG test taken over?
The tTG tests stands for tissue transglutaminase. It is an antibody test. The tTG is NOT a gluten test. No, the tTG test does not replace the gliadin antibody test. The tTG can ONLY indicate if you have tissue damage (in the gut). However, a high tTG level infers that gluten has damaged the gut – but it is not so accurate. The tTG, it is not a perfect test, especially in children. To repeat the message, the tTG tests does not tell you anything about gluten reactivity. However, the tTG test is useful in detecting people who have celiac disease: they, of course, get better when gluten is removed from their diet.
