A tissue transglutaminase (tTG) IgA and/or IgG test is used as part of an evaluation for certain autoimmune conditions, most notably celiac disease. An autoimmune disease can occur when the body’s immune system mistakenly perceives a nonthreatening substance.
What is a positive tTG IgA?
Tissue Transglutaminase Antibodies (tTG-IgA) – the tTG-IgA test will be positive in about 98% of patients with celiac disease who are on a gluten-containing diet. The test’s sensitivity measures how correctly it identifies those with the disease.
What does a negative IgG test mean?

What is tissue transglutaminase AB IgG?

What is transglutaminase IgG?
