Tissue transglutaminaseIgA normal range Celiac disease (CD) is an autoimmune disorder triggered by the ingestion of gluten, a protein found in wheat, barley, and rye. In individuals with celiac disease, consuming gluten leads to an immune response that damages the small intestine.Deamidated gliadin IgAhas sensitivity and specificity for celiac disease diagnosis of approximately 87% and 97%, respectively. Detecting specific antibodies in the blood is a crucial first step in diagnosing celiac disease, and among the most significant are tissue transglutaminase antibodies and deamidated gliadin peptide antibodies, specifically IgA and IgG subtypes.作者：SK Sayed·2012·被引用次数：8—Deamidated gliadin peptideantibodies have recently been suggested as reliable tools for celiac disease (CD) diagnosis.

The Role of Antibodies in Celiac Disease Detection

When gluten is ingested by someone with celiac disease, the body mistakenly identifies gliadin, a component of gluten, as a threat. This triggers the production of various antibodies.作者：GN Catassi·2021·被引用次数：42—Antibodies against syntheticdeamidated gliadin peptidesandtissue transglutaminasefor the identification of childhood celiac disease. Clin. Gastroenterol ... Two key enzymes in this process are tissue transglutaminase (often abbreviated as tTG) and deamidated gliadin peptide (DGP).Isolated positive deamidated gliadin peptide‐IgG has ... The immune system targets these substances, leading to inflammation and damage to the villi in the small intestine.

Blood tests look for the presence and levels of IgA and IgG antibodies against these targets作者：SK Sayed·2012·被引用次数：8—Deamidated gliadin peptideantibodies have recently been suggested as reliable tools for celiac disease (CD) diagnosis.

* Tissue Transglutaminase IgA (tTG-IgA): This antibody is considered the most sensitive and specific first-line screening test for celiac disease. Transglutaminase (tTG) immunoglobulin A (IgA) antibody is highly recommended for initial celiac disease screening. Elevated levels of tTG-IgA are strongly indicative of celiac disease in individuals consuming glutenMeta-analysis: deamidated gliadin peptide antibody ... - NCBI.

* Tissue Transglutaminase IgG (tTG-IgG): This antibody is also measured, particularly in individuals with a selective IgA deficiency, where their body produces low levels of IgA. In such cases, tTG-IgG can still accurately detect celiac disease.

* Deamidated Gliadin Peptide IgA (DGP-IgA): Deamidated gliadin peptide (DGP) refers to gliadin peptides that have undergone a chemical modification. These modified peptides are even more immunogenic in individuals with celiac diseaseTissue Transglutaminase IgA (tTg-IgA) Blood Test - Kids Health. Deamidated gliadin peptide antibody testing, specifically Deamidated gliadin IgA, has shown high sensitivity and specificity for celiac disease diagnosis, typically around 87% and 97%, respectivelyCorrelation analysis of celiac sprue tissue .... This test is particularly useful for diagnosing celiac disease in very young children and in those with certain genetic predispositions.

* Deamidated Gliadin Peptide IgG (DGP-IgG): Similar to tTG-IgG, deamidated gliadin IgG is important for individuals with IgA deficiency164010: Celiac Antibodies Profile tTG IgA, tTG IgG, DGP .... This test looks for the level of deamidated gliadin antibodies (DMG) in your blood. Gliadin is one of the main proteins in gluten.

Combined Testing Strategies and Diagnostic Utility

While tissue transglutaminase antibody tests have historically outperformed deamidated gliadin peptides antibody tests for detecting coeliac disease in some studies, current diagnostic approaches often utilize a combination of these tests to enhance accuracyUtilizing both IgA tissue transglutaminase and IgG- .... A comprehensive Celiac Disease Panel may include IgA and IgG anti-Tissue Transglutaminase and IgA and IgG anti-Deamidated Gliadin.

Research suggests that utilizing both IgA tissue transglutaminase and DGPIgA alongside IgG antibodies in a single-step approach can be considered a valid confirmatory strategy for definitive non-biopsy diagnosis of CeD. Some studies have compared the serum antibody levels for DGP (Ig-G and Ig-A) with tTG-IgA in patients with CD undergoing a gluten free diet (GFD). The aim is to understand how these antibodies behave in response to dietary changesTissue Transglutaminase Antibodies, IgA and IgG Profile ....

It's important to note that a positive result for deamidated gliadin peptide IgG in the setting of a negative tissue transglutaminase-IgA might have a lower positive predictive value for celiac disease in children. However, gliadin IgG and tTGIgA have moderately lower positivity rates, while Anti-tTGIgG shows the lowest but still significant positivity.

Interpreting Test Results and Clinical Significance

A positive result for tissue transglutaminase (tTG) IgA or IgG antibodies is consistent with a diagnosis for celiac disease and possibly for dermatitis herpetiformis. Elevated tissue transglutaminase IgA meaning is a strong indicator of active celiac disease in individuals consuming gluten. Similarly, positive deamidated gliadin peptides in conjunction with tissue transglutaminase antibodies are key biomarkers.

The IgG (Immunoglobulin G) gliadin and transglutaminase test is primarily used to diagnose celiac disease, particularly in patients with selective IgA deficiency. For comprehensive diagnostic evaluation, a Celiac Antibodies Profile test may include deamidated gliadin IgA; deamidated gliadin IgG; tissue transglutaminase (tTG), IgA; tissue transglutaminase (tTG), IgG; and serum IgA quantitation作者：NR Lewis·2010·被引用次数：314—The authors concluded thattissue transglutaminase antibodytest outperformeddeamidated gliadin peptides antibodytest for detection of coeliac disease.. This thorough approach ensures that various antibody subtypes are assessed for a more definitive diagnosis.

In summary, tissue transglutaminase and deamidated gliadin peptide immunoglobulin a and g tests play a crucial role in the diagnosis of celiac diseaseDeamidated Gliadin Antibody. The interpretation of these antibodies should always be done in the context of a patient's clinical presentation, ongoing adherence to a gluten-containing diet, and in consultation with a healthcare professional.Deamidated gliadin IgAhas sensitivity and specificity for celiac disease diagnosis of approximately 87% and 97%, respectively.
