Gliadin Antibodies (IgG)
The Gliadin Antibodies (IgG) blood test measures IgG antibodies produced by the immune system in response to gliadin, a protein found in gluten. Gluten is present in wheat, barley, and rye, and in some individuals it can trigger an abnormal immune response that affects the digestive system and overall health.
Testing for gliadin antibodies is commonly used as part of the investigation into gluten sensitivity, coeliac disease, or unexplained gastrointestinal and nutritional symptoms. These antibodies help indicate whether the immune system is reacting to gluten exposure.

What are gliadin antibodies?
Gliadin is a component of gluten that can stimulate an immune response in susceptible individuals. When the body reacts to gliadin, it produces specific antibodies that can be detected in the blood.
IgG gliadin antibodies provide insight into how the immune system is responding to gluten. Different antibody types can reflect different immune pathways and are often interpreted alongside other coeliac-related tests.
Why might I need this test?
This test may be recommended if you experience symptoms such as chronic diarrhoea, bloating, abdominal pain, unexplained weight loss, fatigue, or nutrient deficiencies. It is also useful when investigating anaemia or bone health issues where malabsorption may be suspected.
Gliadin antibody testing may also be requested if you have a family history of coeliac disease or gluten sensitivity, or if symptoms persist despite normal initial screening results.
What do the results mean?
Raised gliadin antibody levels suggest an immune response to gluten. This does not confirm a diagnosis on its own but supports further assessment for coeliac disease or gluten-related disorders.
Normal results make significant gluten-related immune activity less likely. Results are always interpreted alongside symptoms, dietary history, and other blood tests. Your healthcare professional will explain what your result means and whether further testing is required.
How is the test performed?
The test is performed using a blood sample collected during a short appointment. The procedure is routine and well tolerated.
Do I need to prepare the test?
You should continue consuming gluten in your diet before testing unless advised otherwise, as removing gluten too early can affect test accuracy. No fasting is required.
