About this test

The tTG IgG test detects antibodies associated with celiac disease, especially in individuals with IgA deficiency.

The Tissue Transglutaminase (tTG) Antibody, IgG test is a blood test used to detect IgG antibodies against tissue transglutaminase, an enzyme involved in the immune response in celiac disease.

This test is particularly useful in individuals who have IgA deficiency, where the standard tTG IgA test may give false-negative results. The presence of tTG IgG antibodies helps in identifying gluten-related immune reactions and supports the diagnosis of celiac disease.

The purpose of this test is to

  • To detect tTG IgG antibodies
  • To support diagnosis of celiac disease
  • To evaluate patients with IgA deficiency
  • To assess immune response to gluten
  • To guide further diagnostic evaluation
