Thank you for the clarifcation, how can I get to the bottom of this as to why they may be elevated even on a super strict gluten-free diet? 

Hi, Please can I ask for opinions on using Anti-inflammatories for symptom treatment of inadvertent gluten exposure? Should it be part of a foundational treatment plan, upon inadvertent exposure? Kind Regards,  Bronwyn 

In testing for celiac disease total IgA is run just to be sure you’re not deficient (in which case the TTG IgA results would not be reliable). Different labs may have slightly different normal ranges, but the units are usually the same and the results can be compared.  In your case, what is meaningful for celiac disease is that you were not deficient in total IgA for either test. Different labs use different units for the TTG IgA test and there are no conversion factors to turn one into the other. In your case, the labs have another difference - one uses a weak positive category and one doesn’t.  The two results really can’t be compared. In each case you’re slightly into the full positive range for that test/lab so in reality your antibodies might not have jumped up at all between these two tests.  

Does this mean those could raise IgA and TTG IgA in celiacs?
