The finding of tissue transglutaminase (tTG)-IgA antibodies is specific for celiac disease and possibly for dermatitis herpetiformis. For individuals with moderately to strongly positive results, a diagnosis of celiac disease is likely and the patient should undergo biopsy to confirm the diagnosis.

A tissue transglutaminase IgA (tTg-IgA) test is used to help doctors diagnose celiac disease. Celiac disease is an autoimmune disorder in which the immune system mistakenly thinks that gluten — a protein in wheat, barley, rye, and oats — is a foreign invader. The immune system makes antibodies that attack an enzyme in the intestines called tissue transglutaminase (tTG).

Presence of the tissue transglutaminase (tTG) IgA antibody is associated with glutensensitive enteropathies such as celiac disease and dermatitis herpetiformis. tTG IgA antibody concentrations greater than 40 U/mL usually correlate with results of duodenal biopsies consistent with a diagnosis of celiac disease. Anti-Tissue-Transglutaminase IgA is an ELISA test system for the quantitative measurement of IgA class autoantibodies to tissue transglutaminase (tTG) in human serum or plasma. This product is intended for professional in vitro diagnostic use only. Human recombinant tissue transglutaminase is bound to microwells. The determination is based on an indirect enzyme linked immune reaction with […] Apart from the tTG-IgA test, some other diagnostic tests available are-Total serum IgA test– It checks an individual for IgA deficiency.

Biopsi er gullstandard for oppfølging, og ved symptomer og normal anti-tTG kan biopsi overveies. Verdien av anti-deamidert gliadin IgG ved diettbehandling er mer usikker.

The role of immunoglobulin A (IgA) anti-tissue transglutaminase antibodies (IgA-tTG) as predictors of untreated celiac disease (CoD) is well documented, and the presence and levels of these antibodies are most accurately monitored with native or recombinant human antigens. However, IgA-deficient CoD patients are not identified by IgA serology, and conflicting results concerning the diagnostic
