Tissue transglutaminase (abbreviated as tTG or TG2) is a 78-kDa, calcium-dependent enzyme (EC 22.214.171.124) of the protein-glutamine γ-glutamyltransferases family (or simply transglutaminase family). 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 Anti-tissue Transglutaminase Antibodies, IgA – abbreviated tTG-IgA. [Note: these are substances produced by your immune system that is directed or targeted against “self” tissue – meaning parts of your own body.

It is present in high concentrations in the mucus membranes of the stomach. 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.

Background: Tissue transglutaminase (tTG) immunoglobulin A (IgA) testing is a sensitive adjunct to the diagnosis of coeliac disease. The threshold for positivity was developed for diagnosis, with negative results reported as below the reference value (<4 U/mL). 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 Blood Tests in Celiac Disease on celiacnow.org. 2020-09-08
Tissue Transglutaminase Ab IgA = 1.5 units/ml (ref range <4.0 (negative)) Tissue Transglutaminase Ab Igg = 19.2 units/ml (ref range <6.0 (negative)) I was told by the GI that my blood test indicates Celiac so she said she would take a small intestine biopsy during my scope. The results of my biopsy were completely healthy/normal.
