Fasting Required: No

Specimen: Blood

Results: 7-10 Business Days

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):
