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

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.
