Test Code

The TTG-IgG (Tissue Transglutaminase IgG Antibody) test measures IgG class antibodies produced against tissue transglutaminase, an enzyme involved in intestinal mucosal repair.

This test is particularly useful in patients with selective IgA deficiency, where the standard TTG-IgA test may give false-negative results. Elevated TTG-IgG levels suggest an immune reaction to gluten and support the diagnosis of celiac disease or gluten-sensitive enteropathy. The test is commonly used alongside Total IgA and TTG-IgA for accurate evaluation and may be followed by intestinal biopsy for confirmation.
