A tissue transglutaminase IgA (tTg-IgA) test is used to help doctors diagnose celiac disease or to see how well people with the condition are doing. Using receiver operating characteristic curve analysis we identified a cut-off value for tTG IgA of ≥0.10 μ/mL to be predictive for the absence of total IgA deficiency (IgA<0.06 g/L). Specifically, using this cut-off value, total IgA deficiency could be excluded with a sensitivity of 0.92 and specificity of 0.84. Vid serologisk diagnostik och uppföljning av celiaki är antikroppar av IgA - typ mot transglutaminas rekommenderad förstahandsanalys. Ett negativt testresultat har mycket högt negativt prediktivt värde (NPV), d v s utesluter med stor sannolikhet celiaki, och ett klart förhöjt värde (> 10 ggr gränsvärdet) talar starkt för diagnosen.

Edited November 28, 2012 by NStock The IgG antigliadin antibody test (AGA) mentioned in the question above is an older test that is not routinely checked these days because it is much less accurate than the more current TTG-IgA (tissue transglutaminase) antibody test or the IgA EMA (endomysial antibody) test. 1.

What is 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. A tissue transglutaminase (tTG) IgA and/or IgG test is used as part of an evaluation for certain autoimmune conditions, most notably celiac disease. An autoimmune disease can occur when the body’s immune system mistakenly perceives a nonthreatening substance. 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.

Variance in normal IgA levels by age is sometimes an indicator of an ailment called Celiac Disease. Normal Immunoglobulin A (IgA) level based on age 0 - 18+ years is 7 - 356 mg/dL 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. Presence of the tissue transglutaminase (tTG) IgA antibody is associated with glutensensitive enteropathies such as celiac disease and dermatitis herpetiformis.

Tissue transglutaminase (abbreviated as tTG or TG2) is a 78-kDa, calcium-dependent enzyme (EC of the protein-glutamine γ-glutamyltransferases family (or simply transglutaminase family). If total IgA is normal and tissue transglutaminase (tTG)-IgA is negative, there is a low probability of the patient having celiac disease and a biopsy may not be necessary. If serology is negative or there is substantial clinical doubt remaining, then further investigation should be performed with endoscopy and bowel biopsy. Tissue Transglutaminase (tTG) has been identified as the endomysial antigen. Studies have demonstrated that endomysial IgA antibodies have over 99% specificity for gluten sensitive enteropathy.
