Are These The Tests I Need For Diagnosis?


Lymetoo

My neurologist thinks my small fiber neuropathy is either from Sjogren's (which I have) or from celiac disease. I've been tested for it before (30 yrs ago) but they missed it. I figured it out on my own about 6 yrs ago and have been gluten free ever since.

However, if I am truly a celiac, I will be even MORE VIGILANT than I already am.

These are the tests he ordered:

Transglutaminase IgG

Anti-Gliadin AB

Will these be pretty definitive?? Even if I haven't been eating gluten??

THANKS!!!!

If you are gluten-free already, these tests will probably not be conclusive since they look for the Gliadin reaction! the "gene" test however is not conditional to this. Here is one of the best labs testing currently for Celiac Disease, and they have good notes. This site also explains "testing" as well..good luck

GRRRRR,,,, That's what I thought. I had been wanting the DNA test. Will a DNA test thru another lab be OK??

thanks!

      What you’re describing is actually very common, and unfortunately the timing of the biopsy likely explains the confusion. Yes, it is absolutely possible for the small intestine to heal enough in three months on a strict gluten-free diet to produce a normal or near-normal biopsy, especially when damage was mild to begin with. In contrast, celiac antibodies can stay elevated for many months or even years after gluten removal, so persistently high antibody levels alongside the celiac genes and clear nutrient deficiencies strongly point to celiac disease, even if you don’t feel symptoms. Many people with celiac are asymptomatic but still develop iron and vitamin deficiencies and silent intestinal damage. The lack of immediate symptoms makes it harder emotionally, but it doesn’t mean gluten isn’t harming you. Most specialists would consider this a case of celiac disease with a false-negative biopsy due to early healing rather than “something else,” and staying consistently gluten-free is what protects you long-term—even when your body doesn’t protest right away.

      Yes, I meant if you had celiac disease but went gluten-free before screening, your results would end up false-negative. As @trents mentioned, this can also happen when a total IGA test isn't done.

      I found at Disney springs and Disney they have specialist that when told about dietary restrictions they come and talk to you ,explain cross contamination measures tsken and work with you on choices. Its the one place I dont worry once I've explained I have celiac disease.  Thier gluten free options are awesome.

      Have you tried Pure Encapsulations supplements? This is a brand my doctor recommends for me. I have no issues with this brand.
