Glutenintolerans 4Health.se by Anna Sparre

Transglutaminases are a family of enzymes that catalyze amide bond formation between the γ-carboxamide side-chain group of Gln and primary amines, such as the ε-amino group of Lys.41 The clotting enzyme factor XIII and tissue transglutaminase (tTG) are both calcium-dependent transglutaminases, whereas microbial transglutaminase (mTG) is not. When requesting tests for adults, NICE recommends: test for total immunological immunoglobin A (IgA) and IgA tissue transglutaminase as a first choice test use IgA endomysial antibodies (EMA) if IgA tTG is weakly positive consider using IgG EMA, IgG deamidated gliadin peptide (DGP) or IgG tTG in cases of IgA deficiency. 2021-04-21 · Tissue Transglutaminase Antibody or TTGA - IgA is a single effective test to diagnose Celiac Disease. This disease is characterized by unwarranted response to gluten in the diet.

An autoimmune disease can occur when the body’s immune system mistakenly perceives a nonthreatening substance. 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 finding of tissue transglutaminase (tTG) IgA antibodies is specific for celiac disease and possibly for dermatitis herpetiformis.

Preparation Instructions Test Use ultrapure water (17 M cm or equivalent) for the preparation of reagents and throughout the procedure.

The tissue anti-transglutaminase antibody test has superior sensitivity for Celiac disease than anti-endomysial antibody test, except in young children and patients with total IgA deficiency. Anti-endomysial antibodies test requests outside of these circumstances require Clinical Chemist approval The most common and modern blood tests used to diagnose celiac disease are: Tissue transglutaminase IgA antibody level (commonly referred to as "tTG") Deamidated Gliadin Peptide IgA/IgG antibody level (commonly referred to as DGP) Here’s a short excerpt from … 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 which are even more specific but though the test is technically more demanding and time consuming to perform.
