Transglutaminase IgG

Transglutaminase IgG (tTG-IgG) is a specific antibody test used in the diagnosis of celiac disease and other gluten-related disorders. This test measures the IgG antibodies against tissue transglutaminase, an enzyme found in the intestinal lining. Unlike the more common Transglutaminase IgA (tTG-IgA) test, the tTG-IgG is typically used when a patient has a deficiency in IgA or when IgA test results are ambiguous. It helps in identifying gluten intolerance by indicating an immune response that occurs when a person with celiac disease consumes gluten, leading to an autoimmune reaction that damages the small intestine....

Transglutaminase IgG

What are the typical symptoms indicating a need for the Transglutaminase IgG test?

Symptoms that might indicate a need for testing include gastrointestinal issues like chronic diarrhea and abdominal pain, as well as extraintestinal symptoms such as anemia, dermatitis herpetiformis (a skin rash), and growth problems in children, all of which could suggest celiac disease.

How is the Transglutaminase IgG test performed?

The test requires a blood sample from the patient. This sample is analyzed in a laboratory to measure the levels of IgG antibodies against tissue transglutaminase. Elevated levels of these antibodies suggest an immune reaction to gluten.

What causes positive results in a Transglutaminase IgG test?

A positive result typically indicates an autoimmune response to gluten, as seen in celiac disease, where the body’s immune system mistakenly targets the small intestine. This reaction is triggered by the ingestion of gluten-containing foods.

Who should undergo the Transglutaminase IgG test?

The tTG-IgG test is recommended for individuals who show symptoms of celiac disease but have an IgA deficiency, making the tTG-IgA test less useful. Symptoms prompting this test include chronic diarrhea, abdominal pain, bloating, weight loss, and malnutrition.
