TISSUE TRANSGLUTAMINASE (TTG) ANTIBODY, IGG

This assay is useful in evaluating patients with Celiac disease including those with compatible symptoms, atypical symptoms and individuals at increased risk such as those positive for HLA DA2/DQ8 . It is also used as a screeing test for Dermatitis herpetiformis. This assay also monitors adherence to gluten free diet. Test sensitivity increases from 91.5% for tTG IgA antibody alone to 98.5 % when both IgA and IgG antibodies are tested together.
