Hello! I have hashimoto's and asked my doctor to check labs for celiac. My ttg iga and ttg igg both cameback positive at 39 and 37, greater than 10 is positive. I'm going for an endoscopy in two weeks. I've heard that having an autoimmune thyroid condition could maybe cause a false positive lab. I'm just wondering what your labs were and if your biopsy ended up being positive or not. Thank you so much!

I don't know if I've seen a study that examined % of the false positives from other AI diseases.

Bottom line, lots of people with Hashis are Celiac. That's what the endoscopy and gluten-free trial are for.

Perhaps you can search PubMed, etc.and you can find a study or article?

Apparently there is nothing that cannot happen today. ~ Mark Twain

Probable Endometriosis, in remission from childbirth since 2002.
Hashimoto's DX 2005.
Gluten-Free since 6/2011.
DH (and therefore Celiac) dx from ND
.
Responsive to iodine withdrawal for DH (see quote, above).

Genetic tests reveal half DQ2, half DQ8 - I'm a weird bird!
