The high sensitivity and specificity of the anti-transglutaminase IgA autoantibody assays, respectively 96-98% and 93-95%, 12 associated with the objectivity and full automation offered by the test, have meant that in recent years anti-t-TG IgA testing has superseded older serological tests for CD. 13 Testing for anti-endomysial IgA antibodies (EMA) nevertheless plays an important role in

However, patients with celiac disease are at higher risk of having IgA deficiency. In this setting, IgA-based testing for celiac disease is often negative, complicating the clinical picture. In terms of serology, celiac disease is associated with a variety of autoantibodies, including endomysial, tissue transglutaminase (tTG), and deamidated gliadin antibodies. Although the IgA isotype of these antibodies usually predominates in celiac disease, individuals may also produce IgG isotypes, particularly if the individual is IgA deficient.

Celiac disease is an autoimmune disorder. This means your body attacks itself. This test is also used to see how well people with the condition are doing. 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.

Because IgA antibodies typically predominate in celiac disease, testing for tissue transglutaminase (tTG) IgA antibodies is preferred over tTG IgG antibodies, except in the presence of IgA deficiency. This test should not be solely relied upon to establish a diagnosis of celiac disease.

tTG IgA antibody concentrations greater than 10 U/mL usually correlate with results of duodenal biopsies consistent with a diagnosis of celiac disease. Tissue Transglutaminase Antibody (TTG) Alternative name: Coeliac Screen: Description: IgA anti-tissue transglutaminase antibodies are now used as the preferred test for screening of coeliac disease and dermatitis herpetiformis, being highly (>90%) sensitive and specific. All positive samples are then tested for IgA anti-endomysial antibodies Test Code TTGIGA Transglutaminase Antibody (Anti-tTG), IgA, Serum Additional Codes.

Clinical Significance Tissue Transglutaminase (tTG) Antibody (IgA) - Tissue Transglutaminase Antibody, IgA, is useful in diagnosing gluten-sensitive enteropathies, such as Celiac Sprue Disease, and an associated skin condition, dermatitis herpetiformis.

It is one of several blood tests that may be used to help diagnose celiac disease. Tissue transglutaminase is an enzyme that fixes damage in your body. People with celiac disease often make antibodies that attack this enzyme. These are called anti-tissue transglutaminase antibodies. Tissue transglutaminase antibody (tTG), IgA class — the primary test ordered to screen for celiac disease.

The test’s sensitivity measures how correctly it identifies those with the disease.

These are called anti-tissue transglutaminase antibodies.

Objective: Measuring serum tissue transglutaminase immunoglobulin A (tTG IgA) levels is the most widely used screening test for coeliac disease. However, given an increased prevalence of IgA deficiency among coeliac patients there is a risk of false negative results.

Tissue Transglutaminase Antibody, IgA: Presence of the tissue transglutaminase (tTG) IgA antibody is associated with gluten-sensitive enteropathies such as celiac disease and dermatitis herpetiformis. tTG IgA antibody concentrations greater than 10 U/mL usually correlate with results of duodenal biopsies consistent with a diagnosis of celiac disease.

The antigen of endomysium in CD serology is transglutaminase. IgA anti-transglutaminase antibodies, which are analyzed with ELISA, correlate very well with anti-endomysium, which is analyzed with indirect immunofluorescence. The high sensitivity and specificity of the anti-transglutaminase IgA autoantibody assays, respectively 96-98% and 93-95%, 12 associated with the objectivity and full automation offered by the test, have meant that in recent years anti-t-TG IgA testing has superseded older serological tests for CD. 13 Testing for anti-endomysial IgA antibodies (EMA) nevertheless plays an important role in 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 Elevation of IgG antibodies against tissue transglutaminase as a diagnostic tool for coeliac disease in selective IgA deficiency.
