Antitransglutaminase IgA level

 

I was diagnosed with CD in 2006 and been on a gluten free diet since then - although, I would say there has been a goof up approximately 1-2x's/year (usually from putting too much faith in restaurant staff). My doctor recently tested my anti-transglutaminase IgA and it is still at 11.  The legend on the lab work says <7 is negative, 7-10 is weak positive and >10 is positive.  So obviously, I am still getting gluten.  Is 11 low enough that it could just be due to my"goof ups" or would it be so high that it indicates that I am getting gluten more often (in which case, I would have no idea where it is coming from and I will have to make some major adjustments to my diet to figure it out).  My doctor couldn't tell me how significant a level of 11 is.  Think 11 would cause major symptoms?  Thanks for your time!!
