tTG IgG Blood Test - More Information

The tTG IgG test, also known as a tTG IgG blood test and a tissue transglutaminase IgG antibody lab test, measures the tTG IgG antibody blood levels.

Tissue transglutaminase, or tTG, IgG antibodies are proteins produced by the immune system. Also known a tTG immunoglobulin G, tTG IgG antibodies are often present in people with celiac disease and are involved with destroying the intestinal villi. The tTG IgG antibody test is frequently ordered with the tTG IgA test which, together, make up the commonly ordered tTG blood test panel. The tTG IgG blood test is useful for helping to identify patients with celiac disease and an IgA deficiency which is why it is also part of the celiac disease test panel.
