The tTG IgG assay may aid in the diagnosis of gluten-sensitivity enteropathy (i.e., celiac disease, dermatitis herpetiformis) in tTG IgA negative patients with confirmed IgA deficiency. A negative tTG IgG test alone does not rule out gluten-sensitive enteropathy.
Native human tTG antigen is utilized in this assay
