I'm so sorry that you are going through this. Please share here whenever you need to.

My MIL has celiac. There is a blood test they can do to confirm but I think that you need to be eating gluten for the results to be useful. She nearly died before they figured out what it was. First GI doctor totally missed it. Put her through all kinds of tests. Would have been so much easier if he had just tested for this first.

I have the benign thyroid nodule. Went through the tests after being told that it could be cancer. The primary doctor sent me for the ultrasound and then the radioactive thing (not a medical term ) The endo did a needle biopsy in her office and confirmed that it was benign. She said that I hadn't needed the other tests.
