Anti Tissue Transglutaminase IgG test is based on the binding of serum or plasma antibodies on the human recombinant tissue transglutaminase coated into the microplates. The most common and modern blood tests used to diagnose celiac disease are: Tissue transglutaminase IgA antibody level (commonly referred to as "tTG") Deamidated Gliadin Peptide IgA/IgG antibody level (commonly referred to as DGP) Here’s a short excerpt from Blood Tests in Celiac Disease on celiacnow.org. A blood test that shows higher levels of anti-tissue transglutaminase antibodies can help your healthcare provider figure out if you have celiac disease. If deamidated gliadin antibodies or IgG specific tissue transglutaminase antibodies/gliadin antibodies are required see: DEAMIDATED GLIADIN AB When claim type is MSP or Other Provincial payer and TTG is ordered in combination with: IGA & TTG.
