Didn't know Celiac was a possibility

[OakLeaf]

I wish Knott were still here ...

I don't have celiac, but you got me curious, and this is the most accessible and apparently accurate summary I found on a quick google. Do you know what antibodies they tested for?

I'm assuming that since an OB/GYN isn't trained to either diagnose or treat autoimmune disorders, that they'll be referring you either to a gastroenterologist or an immunologist. That doctor will be able to answer your questions a lot better than any of us - make a list of your questions so you don't forget any. I personally would not schedule a biopsy before you've had the opportunity to talk it over with the doctor and understand why it's indicated (if it is) and what the potential benefits would be rather than just electing a gluten-free life without a biopsy-confirmed diagnosis - but that's just my personal opinion.
