Tissue Transglutaminase Antibody, IgA
Human RBC tTG - Native tTG - TG2 IgA - Tissue Transglutaminase - Tissue Transglutaminase Ab IgA - tTG IgA - tTG IGA - TTG-IgA Antibody
Tissue Transglutaminase Antibody, IgA ELISA and Interpretation
The endomysial antigen has been identified as the protein cross-linking enzyme known as tissue transglutaminase. Detection of tissue transglutaminase antibodies is an aid in the diagnosis of certain gluten-sensitive enteropathies, such as celiac disease and dermatitis herpetiformis. Human tTG antigen is utilized in this assay.
