Tissue transglutaminase, or tTG, IgA antibodies are proteins produced by the immune system. Also known a tTG immunoglobulin A, tTG IgA antibodies are quite commonly found in people with celiac disease. The tTG IgA antibody test is frequently ordered with the tTG IgG test which are both part of the tTG blood test panel. The tTG IgA blood test is also part of the celiac disease test panel.
