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. :)

      Waiting Gastroenterology review

      By RMJ · Posted

      That means the normal range (i.e. not celiac disease) would be a result less than 14.99.  Your result is WAY above that. Some gastroenterologists would diagnose that as celiac disease even without a confirming biopsy because it is more than ten times the top of the normal range.

      Diagnosis and further testing Celiac

      By Redanafs · Posted

      Hi everyone. Back in 2022 I had blood work drawn for iga ext gliadin. Since then I’ve developed worse stomach issues and all other health issues. My doctor just said cut out gluten. He did no further testing. Please see my test results attached. I just need some direction cause I feel so ill and the stomach pain is becoming worse. Can this test show indications for other gastrointestinal diseases?

      Thank you. These were the results TTG ABS NUMERICAL: > 250.0 U/mL [< 14.99]  Really don’t understand the results!

      Does Dailymed.nlm.nih.gov site have filters for gluten?

      By Scott Adams · Posted

      Clearly from what you've said the info on Dailymed is much more up to date than the other site, which hasn't been updated since 2017. The fact that some companies might be repackaging drugs does not mean the info on the ingredients is not correct.

      To evaluate the TTG antibody result we’d need to know the normal range for that lab.  Labs don’t all use the same units.  However, based on any normal ranges that I’ve seen and the listed result being greater than a number rather than a specific number, I’d say yes, that is high! Higher than the range where the test can give a quantitative result. You got good advice not to change your diet yet.  If you went gluten free your intestines would start to heal, confusing any further testing,
