Is The Ttga Test Specific To Gluten Only?

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. :)

      Sainsbury's Free From White Sliced Bread - Now Egg Free - Completely Ruined It

      More great tips, and a good excuse to shop at M&S and also buy more iced buns!   I wish we had an ASDA near us, as the few times we've been to one their gluten-free pasta range seemed very reasonably priced compared to other shops.  Thanks so much, @Russ H.

      Shingles - Could It Be Related to Gluten/ Celiac

      By Russ H · Posted

      I hope you are on the mend soon. About 1 in 5 people who contracted chicken pox as a child go on to develop shingles in later life - it is not uncommon. There are 5 known members of the herpes virus family including chicken pox that commonly infect humans, and they all cause lifelong infections. The exact cause of viral reactivation as in the case of shingles or cold sores is not well understood, but stress, sunburn and radiotherapy treatment are known triggers. Some of the herpes viruses are implicated in triggering autoimmune diseases: Epstein-Barr virus is suspected of triggering multiple sclerosis and lupus, and there is a case where it is suspected of triggering coeliac disease. As to whether coeliac disease can increase the likelihood of viral reactivation, there have been several cohort studies including a large one in Sweden suggesting that coeliac disease is associated with a moderate increase in the likelihood of developing shingles in people over the age of 50.

      BFree bread is fortified with vitamins and minerals as is ASDA own-brand gluten-free bread. All the M&S bread seems to be fortified also.

      Shingles - Could It Be Related to Gluten/ Celiac

      By Flash1970 · Posted

      You might try Heallix.  It's a silver solution with fulvic acid. I just put the solution on with a cotton ball.  It seemed to stop the nerve pain. Again,  not in your eyes or ears.   Go to heallix.com to read more about it and decide for yourself Also,  I do think nerve and celiac combined have a lot to do with your susceptibility to shingles breaking out.

      GI DX celiac despite neg serology and no biopsy

      By trents · Posted

      Celiac disease requires both genetic potential and a triggering stress event to activate the genes. Otherwise it remains dormant and only a potential problem. So having the genetic potential is not deterministic for celiac disease. Many more people have the genes than actually develop the disease. But if you don't have the genes, the symptoms are likely being caused by something else.
