Is The Ttga Test Specific To Gluten Only?

[AJJ]

Does anyone know if the TTGa test is specific to gluten only or can it pick up a response to lectin also?

Apologies - I posted the same question into the wrong forum (related disorders) - am just new to all of this.

Ttg IgG or IgA are very specific for celiac disease. They indicate an autoimmune disorder. They look for Ttg IgA because it specific to your GI tract, but IgG can also be involved as well. There are a small number of other diseases that can cause elevated Ttg, like acute liver failure, but the diseases should be pretty obvious if they are present. (I feel confident on my son's diagnosis based off of positive Ttg IgA and dietary response.) So lectin intolerance should not cause elevated Ttg. I hope this answers your question.
