CertifiedLabsWhat is Anti Gliadin Deamidated Peptide antibody IgA Test?
The Gliadin Deamidated Peptide Antibody IgA test is a blood test used to detect coeliac disease and other gluten-sensitive autoimmune disorders, such as dermatitis herpetiformis (also called the cutaneous manifestation of coeliac disease). This test measures IgA antibodies against deamidated gliadin peptides (DGP), which is a more specific and reliable marker for coeliac disease compared to conventional gliadin antibody tests.
Coeliac disease is an autoimmune disorder in which the ingestion of gluten triggers an immune response that damages the small intestine, leading to nutrient malabsorption, anaemia, and other serious health complications. Therefore, IgA antibody testing is highly recommended for accurate diagnosis.
The deamidated gliadin antibody is a better diagnostic test as compared to conventional gliadin antibody testing. The test is useful for diagnosing coeliac disease in individuals experiencing symptoms. It also helps in monitoring dietary compliance in patients following a gluten-free diet. Additionally, this test is used for screening high-risk individuals with a family history of coeliac disease.
For individuals in Bangalore willing to screen for gluten-related disorders like coeliac disease, it is recommended to schedule a Gliadin Deamidated Peptide Antibody IgA test at home.
Anti Gliadin Deamidated Peptide antibody IgA Test Parameters
The DGP antibody IgA test detects IgA antibodies against DGPs, which are modified forms of gliadin that provoke a stronger immune reaction in coeliac patients. Gliadin is a protein found in gluten, which is present in foods like wheat, barley, and rye. Elevated antibody levels indicate gluten-sensitivity disorders like coeliac disease.
Anti Gliadin Deamidated Peptide antibody IgA Test Preparation
Individuals can seek coeliac disease screening at home with these preparations:
Prerequisites : Fasting is not required for the test. You may continue to consume gluten-containing foods a few weeks before testing.
Best Time to Get Tested : The test can be conducted at any time of the day.
Who Should Get a Gliadin Deamidated Peptide Antibody IgA Test? : The Gliadin Deamidated Peptide Antibody IgA test is recommended for individuals experiencing symptoms of coeliac disease, such as diarrhoea, weight loss, or malabsorption. It is also useful for patients on a gluten-free diet to monitor dietary compliance and for those with a family history of coeliac disease or autoimmune disorders.
Cautions Before Taking a Gliadin Deamidated Peptide Antibody IgA Test : Before taking this test, inform your doctor about any ongoing medications or health conditions that may affect the results.
Why Take the Anti Gliadin Deamidated Peptide antibody IgA Test?
The Gliadin Deamidated Peptide Antibody test is a key diagnostic test for detecting coeliac disease. It also helps assess intestinal damage, monitor treatment response, and ensure dietary compliance.
You may need this test if you:
Experience persistent digestive symptoms like bloating, diarrhoea, constipation, gas, nausea, vomiting, or unexplained weight loss.
Have non-digestive symptoms, including fatigue, headaches, depression, anxiety, irritability (in children), or an itchy, blistering rash.
Have a family history of coeliac disease or other autoimmune disorders, such as type 1 diabetes.
Need to monitor gluten-free diet compliance in previously diagnosed coeliac patients.
Require early detection, even if symptoms are absent but risk factors are present.
Unlike gluten sensitivity or wheat allergies, coeliac disease causes long-term intestinal damage, making early diagnosis and lifelong dietary management essential.
