<<Disclaimer: Verify this information before applying it to your situation.>> Anyone ever have concerns about this topic with celiac disease or find a relationship with high tTG titers? tTG antibodies are a calcium antigen. I go for an EMG for neurological test on April 4th for twitching that has been going on in my right leg (and other body parts) for 24/7 and 2 months. It's not electrolytes. Not calclium, magnesium, nothing like that. That's all been ruled out. Suggestions? Greg Eric
