Tissue Transglutaminase (tTG) Antibody (IgG)
Also known as: Transglutaminase, Tissue Antibody IgG, tTG IgG
Clinical Use
Order TestUse
Tissue Transglutaminase (tTG) IgG antibody aids in diagnosing celiac disease by detecting IgG class antibodies reactive to tissue transglutaminase. It can be used in clinical contexts where IgA-based testing may be unreliable (e.g., IgA deficiency) and to monitor patient response to a gluten-free diet.
