<<Disclaimer: Verify this information before applying it to your situation.>> Dear group - I recently attended a talk by Dr. Fasano, who heads the Celiac Center at University of Maryland. This was in the Chicago area (the talk). He said there is a new blood test, the tTG or tissue Trans Glutamanase test, and that it is 98% accurate for Celiac Sprue. More accurate than IgA, etc. Vicki
