<<Disclaimer: Verify this information before applying it to your situation.>> Hi, I am questioning if I have celiac disease. My doctor wants to do a blood test but I have not eaten wheat for about three weeks (as far as I know). I am still having problems which I have had for several years. I recently started eating a lot of whole wheat bread and found that I felt vey ill on this diet ++++++ diarrhea. I have bordered on being anemic and take vitamin B reg for a lift. I am lactose intolerant. For years I have had red marks across my skin - as if I have been burnt when I am touched. Any one know about any of this? Will the blood test still work without me eating wheat? Thanks Sandy
