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 …

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. “The most frequently used test is the tTG.

Gluten is a protein found in food grains like wheat, rye, barley etc. the body releases antibodies if gluten is ingested. The finding of transglutaminase IgG antibodies may indicate a diagnosis of celiac disease, particularly in individuals who are IgA deficient. For individuals with moderately to strongly positive results, a diagnosis of celiac disease is possible and the patient should undergo a biopsy to confirm the diagnosis.

It is one of several blood tests that may be used to help diagnose celiac disease. Tissue transglutaminase is an enzyme that fixes damage in your body. People with celiac disease often make antibodies that attack this enzyme. These are called anti-tissue transglutaminase antibodies. Tissue transglutaminase antibody (tTG), IgA class — the primary test ordered to screen for 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. Tissue Transglutaminase Antibody (TTG) Alternative name: Coeliac Screen.

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. In the case of people with celiac disease, gluten (a protein found in wheat, barley, rye, and oats) is seen as a foreign invader and is attacked by the immune system.

The finding of transglutaminase IgG antibodies may indicate a diagnosis of celiac disease, particularly in individuals who are IgA deficient. For individuals with moderately to strongly positive results, a diagnosis of celiac disease is possible and the patient should undergo a biopsy to confirm the diagnosis.

In terms of serology, celiac disease is associated with a variety of autoantibodies, including endomysial, tissue transglutaminase (tTG), and deamidated gliadin antibodies. Although the IgA isotype of these antibodies usually predominates in celiac disease, individuals may also produce IgG isotypes, particularly if the individual is IgA deficient. IgA antibodies directed at tissue transglutaminase (TG2) are elevated in gluten‐sensitive diseases including DH and coeliac disease (CD). More recently, antibodies directed at epidermal transglutaminase (TG3) were identified in patients with DH, and this may be the dominant autoantigen in this disease.

Coeliac is an autoimmune disease that affects one in every 100 people worldwide. 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.

Diagnostic accuracy of IgA anti-tissue transglutaminase antibody assays in celiac disease patients with selective IgA deficiency Clinical studies have estimated a 10- to 20-fold increased risk for celiac disease (CD) in patients with selective IgA deficiency (SIgAD). Antibodies against transglutaminase virtually never occur in healthy individuals or in patients with other intestinal diseases, whereas in untreated GSE their prevalence is almost 100%. Transglutaminase antibodies are mostly of the immunoglobulin class IgA. Class IgG occurs in low concentrations in 50% of IgA positive sera.

Recent medical literature agrees that celiac disease (CD) is much more prevalent in western civilization than it was thought to be in the past.
