A.D.
I did research on this at Children's hosp in Denver. I am a dietitian. the blood tests basically test an immune response to gluten, the protein aspect of grains like wheat. High blood levels usually lead to an intestinal biopsy, which is the gold standard of dignosis. the blood tests have improved since we studied them, but they are not perfect. It is good to ask if your specialist has a lot of experience with celiac because the biospsy and labs are best performed by those skilled in this specialty as subtle findings can be missed. Until you are certain I would not change anything (unless your MD advised otherwise). this is because you want the specialist to diagnose your dtr with her usual diet not based on a change. The little villi on the intestines of someone w/ celiac who is eating wheat can be blunted, and they can regenerate when they are off gluten. this occurs much faster w/ kids than adults. there is a local celiac support group in most towns and they can be helpful in getting you started should you need that. Also I can email you book titles and websites on celiac that are reputable. I would wait though and make sure you need them and then email me back. Good luck, you will get through this! A. D
