<<Disclaimer: Verify this information before applying it to your situation.>> Dear Listmates, I have been participating (both as a reader and contributor) to this list for about 3 months now. Finally, I have been officially diagnosed with CD (not that I am happy to have this, just glad to know what I am dealing with so I can get on with my life). My serology tests before going GF came back negative. I suspect the lab may have been the problem and I did not aggressively push for follow-up serology while still on gluten. My diagnosis was confirmed through biopsy for which I had to demand that my samples be sent to the Univ. of MD (after the first lab which my dr. chose indicated that the biopsy was negative for celiac). What a fiasco this process is. It really is amazing how much doctors can mess up your lives. Anyway I am now on a GF diet and have been since the biopsy was done on April 25th. I have two questions about my situation. 1) I seem to be ingesting something (I have been having some mild symptoms) that is giving me trouble and I can't seem to figure out what it could be. I have checked all of the updated lists for safe foods and called companies when not sure. I have been eating alot of corn products (such as GF popcorn, and Tortilla chips) as a replacement to pretezels, etc. Could it be the corn? Is it just that my damaged body needs time to heal and therefore I should eat a low-fiber diet or is it more likely that I am unwittingly ingesting gluten? 2) my second question is, since I did not get a baseline serology how can I monitor whether I am successfully staying GF? SHould I ask my dr. to redo the blood-work now? or should I go back on gluten temporarily in order to redo the bloodwork? I was hoping if any physicians or other experts in this field see this message, that you might be willing to respond either to me or the list (I'm sure there are others with this question.) Thanks for your help. joan Ardmore, PA
