<<Disclaimer: Verify this information before applying it to your situation.>> Hello Listmates, It is time to take my four-year old daughter back to her GI for follow-up blood work. She was diagnosed almost two years ago and its been am little over a year since her last visit. The last time we went, I wasn't confident that the right tests were done. This time, when I call to make the appointment, I want to specify exactly what I expect to have done. Do I repeat IgA, IgG and Endomysial? Are there additional tests I should request like B12 or CBC, etc.? Also, (I think I already know the answer to this one but...)if a biopsy- diagnosed celiac has been following a gluten-free diet, is there any way to verify the diagnosis "beyond a doubt", other than doing a gluten challenge followed by another biopsy? I thank you in advance for your help.
