The Gliadin Antibodies (IgG, Deamidated) Test is a blood test that detects antibodies against deamidated gliadin peptides (DGP), a component of gluten. This test helps identify coeliac disease or non-coeliac gluten sensitivity, particularly in cases where standard tests may not detect an immune response.
Our at-home test kit allows you to check your antibody levels conveniently and privately, with accurate results analysed in accredited UK laboratories.
Gliadin is a protein found in wheat and gluten-containing foods. In people with coeliac disease, the immune system produces antibodies in response to gliadin, causing damage to the small intestine.
The IgG deamidated gliadin peptide (DGP) test is particularly useful when:
Patients have IgA deficiency, which may cause traditional IgA-based tests (like tTG-IgA) to miss coeliac disease
Monitoring gluten-related immune response in people already on a gluten-free diet
Assessing non-classical or atypical symptoms
This test is highly specific and helps identify gluten sensitivity or coeliac disease early, which can prevent long-term complications.
Coeliac disease can remain undiagnosed due to mild or atypical symptoms. Early detection is essential to avoid complications such as:
Malnutrition
Anaemia
Osteoporosis
Infertility or pregnancy complications
Fatigue and digestive issues
Increased risk of autoimmune disorders
Testing for gliadin IgG antibodies can help you understand whether your symptoms are related to gluten and guide dietary or medical decisions.
Symptoms can vary widely and may include:
Bloating, abdominal pain, or diarrhoea
Constipation or irregular bowel movements
Fatigue and low energy
Unexplained weight loss
Anaemia or pale skin
Mouth ulcers
Skin rashes (dermatitis herpetiformis)
Brain fog, irritability, or mood changes
Because these symptoms overlap with other conditions, a blood test is an important first step.
This test is particularly recommended if you:
Experience ongoing digestive symptoms after consuming gluten
Have a family history of coeliac disease
Are diagnosed with IgA deficiency
Are following a gluten-free diet but need antibody monitoring
Have unexplained fatigue, anaemia, or neurological symptoms
