A tissue transglutaminase (tTG) IgA and/or IgG test is used as part of an evaluation for certain autoimmune conditions, most notably celiac disease. Normal values in most labs are 0-3. So your result is normal.
Gliadin deamidated Ab is also a blood test for celiac disease. I have not found the normal range for it yet, but it seems that your values are normal too.
Overall, it is good news. The blood test result does not support a diagnosis of celiac disease (gluten disease)
