I was diagnosed with Celiac just over a year ago. I have adopted a strict gluten-free (and grain-free) diet. I eat very clean, no processed foods, no soy, no dairy etc. yet I am still not feeling better. Very fatigued all the time. I am starting to suspect my thyroid. They checked my TSH when I was diagnosed and it was fine, but in my research I see that TSH is a poor test for Hashimoto's, and what they should be looking for is antibodies. My question is this: since Hashimoto's has a clear link to gluten sensitivity/Celiac, if I get tested for it now, will it come up negative since I have been gluten-free for a year? This week I took my cousin for Celiac testing, as she has many symptoms of Celiac. Come to find out she was diagnosed with Hashimoto's and Graves Disease as a child. So there is a family history. I have booked a doctor's appointment but would like to know what the odds are of a false negative.
Thanks so much!
