ANTI GLIADIN ANTIBODY:IGG

Home Collection

Department: IMMUNOLOGY

The Anti-Gliadin Antibody (IgG) Test is a blood test that measures IgG antibodies produced against gliadin, a protein found in gluten-containing foods like wheat. Elevated levels may indicate an immune response to gluten.

This test is useful in identifying gluten sensitivity and is often used alongside other tests to support the diagnosis of celiac disease.

The Anti Gliadin Antibody (IgG) Test is performed to:

• Detect IgG antibodies against gliadin

• Help evaluate gluten sensitivity

• Support the diagnosis of celiac disease

• Assess malabsorption conditions

• Assist in dietary and treatment planning

ANTI GLIADIN ANTIBODY:IGG Test Purpose

The Anti-Gliadin Antibody (IgG) Test measures the level of IgG antibodies produced by the immune system in response to gliadin, a protein found in wheat, barley, and rye. This test helps evaluate the body’s immune response to gluten and supports the diagnosis of celiac disease and other gluten-related disorders, particularly in individuals who may have IgA deficiency.

Healthcare providers often recommend this test for patients experiencing symptoms such as chronic diarrhea, abdominal pain, bloating, unexplained weight loss, fatigue, anemia, poor nutrient absorption, or delayed growth in children. In addition, it may be used when celiac disease is suspected, but other antibody tests require further confirmation.

Although newer tests, such as Tissue Transglutaminase (tTG) Antibodies, are generally preferred for diagnosing celiac disease, the Anti-Gliadin IgG Test continues to provide valuable information in selected clinical situations. Furthermore, it may assist in evaluating gluten sensitivity and monitoring patients as advised by their healthcare provider.

ANTI GLIADIN ANTIBODY:IGG Test is Recommended for Individuals:

• Individuals with symptoms suggestive of celiac disease.
• People experiencing chronic diarrhea, bloating, abdominal pain, or unexplained weight loss.
• Patients with suspected gluten intolerance or gluten-related disorders.
• Individuals with IgA deficiency require alternative celiac antibody testing.
• Patients with unexplained iron-deficiency anemia or nutritional deficiencies.
• Children with delayed growth or poor weight gain where celiac disease is suspected.
• Individuals with a family history of celiac disease.
• Patients are advised by their healthcare provider to undergo further evaluation for gluten-related conditions.

FAQs

1. What is the Anti-Gliadin Antibody (IgG) Test used for?

The Anti-Gliadin IgG Test detects antibodies against gliadin, a component of gluten. It helps support the diagnosis of celiac disease and other gluten-related disorders, especially in individuals with IgA deficiency or when additional antibody testing is needed.

2. Do I need to fast before the Anti-Gliadin IgG Test?

No. Fasting is generally not required for this blood test. However, you should continue consuming a gluten-containing diet unless your healthcare provider advises otherwise, as avoiding gluten before testing may affect the results.

3. What does a positive Anti-Gliadin IgG result mean?

A positive result suggests that your immune system has produced antibodies against gliadin, which may indicate celiac disease or another gluten-related condition. However, the test alone cannot confirm the diagnosis. Your doctor will interpret the results together with your symptoms, other celiac antibody tests, and, if required, an intestinal biopsy to establish an accurate diagnosis.
