Description
Serum, Tissue Transglutaminase (tTG) is an enzyme responsible for protection, prevention, and tissue remodeling or repair processes. Anti-tTG antibodies are more sensitive and specific than anti-Gliadin antibodies. Screening for tTG-IgA antibodies is recommended to identify patients at risk for celiac disease. This test detects autoantibodies in the blood that the body produces as part of the immune response. It also aids in monitoring adherence to a gluten-free diet in disease confirmed patients., Non Fasting
Sample Required:
The Tissue Transglutaminase Antibody IgA test requires a blood sample. A small amount of blood is drawn from a vein in the arm using a needle.
Test Time:
The test itself usually takes a few minutes to collect the blood sample. However, the processing and analysis of the sample may take a few hours to a couple of days, depending on the laboratory and healthcare facility.
Test Normal Range:
The normal range for Tissue Transglutaminase Antibody IgA may vary depending on the laboratory and the specific testing method used. It is important to consult with a healthcare provider to interpret the results accurately.
What is the Test?
The Tissue Transglutaminase Antibody IgA test is used to help diagnose celiac disease, an autoimmune disorder triggered by the consumption of gluten. This test detects the presence of antibodies called IgA antibodies that target tissue transglutaminase, an enzyme found in the intestine.
Test Procedure:
During the Tissue Transglutaminase Antibody IgA test, a blood sample is collected from a vein in your arm. The blood sample is then sent to a laboratory for analysis. The laboratory uses specific techniques to measure the levels of IgA antibodies against tissue transglutaminase in the serum.
When to take the test?
The Tissue Transglutaminase Antibody IgA test is typically recommended when there is suspicion of celiac disease or gluten intolerance. It is often performed after an individual has been consuming gluten-containing foods to ensure accurate results.
Who should take this test?
Individuals who have symptoms suggestive of celiac disease, such as chronic diarrhea, abdominal pain, unexplained weight loss, or a family history of the condition, may be advised to take the Tissue Transglutaminase Antibody IgA test. Additionally, those at higher risk for celiac disease, such as individuals with certain autoimmune disorders, type 1 diabetes, or a family history of celiac disease, may also undergo this test.
Precautions for exceptional cases (pregnancy, etc.):
It is important to inform the healthcare provider if you are pregnant or have any other exceptional conditions. In some cases, additional considerations may be necessary to ensure accurate interpretation of the test results and appropriate management.
