Description: The finding of IgA-tTG antibodies is highly specific for celiac disease and possibly for dermatitis herpetiformis. Individuals with moderately-to-strongly positive results are highly likely to have celiac disease.
Methodology:
Immunoassay (IA)
Reference Range(s):
<4 U/mL No antibody detected
=4 U/mL Antibody detected
Clinical Significance:
Tissue Transglutaminase Antibody, IgA, is useful in diagnosing gluten-sensitive enteropathies, such as Celiac Sprue Disease, and an associated skin condition, dermatitis herpetiformis.
Alternative Name(s):
Celiac Disease, tTG Antibody, Transglutaminase, Tissue Antibody IgA, Dermatitis Herpetiformis, tTG IgA
