That may give a false negative result when tested for IgA TTG, which may lead to a missed diagnosis. Is this diagnostic of celiac disease or do I still need a biopsy? I also had a pill capsule test which showed signs of flattening of the villi. 2001. pp.

It tests for normal tissue glutaminase levels. OR is it telling me my Tissue transglutaminase is in the equivocal range?? Tissue transglutaminase antibody (tTG), IgA class — the primary test ordered to screen for celiac disease.
Thanks Anti-tissue transglutaminase.

Testing for and diagnosis of normal IgA levels of celiac disease is done using a Glutaminase Test. Total immunoglobulin A and IgA Anti-tissue Transglutaminase Antibody (TTG) are usually the first choice tests performed for diagnosis of coeliac disease. Anti tissue transgluaminase level 1.2u/mL (1-10)-Tissue transglutaminase equivocal range =7-10u/mL Is it just telling me what the equivocal range is? 145–8. The test has a 90% accuracy level. In: Maki M, Tossavaine M, editors.

IgA deficiency is significantly more common in people with coeliac disease in general population.

The test is also called Celiac Disease Blood Test.

Presence of the tissue transglutaminase (tTG) IgA antibody is associated with glutensensitive enteropathies such as celiac disease and dermatitis herpetiformis. Whats the diff between Anti-tissue transglutaminase and Tissue transglutaminase levels? This is the primary test that medical practitioners ask for in the screening for celiac disease. The IgA-less phenotype is more common in CD than the normal population; however, one haplotype, DQ2.5 is found in most CD, has genetic linkage to the IgA-less gene location.

Serum immunoglobulins A and G and monoclonal antibodies anti-tissue transglutaminase from coeliac patients inhibit the catalytic activity both in vitro and in situ. tTG IgA antibody concentrations greater than 40 U/mL usually correlate with results of duodenal biopsies consistent with a diagnosis of celiac disease.

Esposito C, Paparo F, Caputo I, et al. Associated conditions Celiac disease. It is the most sensitive and specific blood test for celiac disease and is the single test preferred by the American College of Gastroenterology and the American Gastroenterology Association for the detection of celiac disease in those over the age of 2 years. Not sure what the doctor's next step will be and what the 95.0 test result is telling me. Proceedings of the Workshop on Transglutaminase, Protein Cross-Linking and Coeliac Disease; Tampere, Finland, University of Tampere.
Tissue transglutaminase is the most specific test for Coeliac Disease. I had the anti-tissue transglutaminase blood test and it says the level should be less than 10.3.

Antibodies to tissue transglutaminase ... ATA IgG are found in CD and at higher levels when affected individual had the IgA-less phenotype.

Mine was 95.0.
