Short Name: Deamidated Gliadin IgG Test
Also known as: Deamidated Gliadin Antibody Test, DGP IgG Test, Gliadin IgG Antibody Test
Gliadin Deamidated Antibody IgG Test test available at DNA Labs India for ₹1,989. Uses Enzyme Immunoassay on Serum samples. Results in Results are typically available within 2-3 working days after sample receipt.. Free home collection in 300+ cities across India.
Overview
The purpose of the Gliadin Deamidated Antibody IgG Test is to detect IgG antibodies against deamidated gliadin in the blood, which are markers for celiac disease and gluten intolerance. This test helps in diagnosing individuals with symptoms such as chronic diarrhea, abdominal pain, and nutrient malabsorption. It is particularly useful when IgA-based tests may be inconclusive, as in cases of selective IgA deficiency. The test supports clinical decision-making for initiating dietary interventions like a gluten-free diet and monitoring disease progression.

Doctor's Notes
"This test is essential for early diagnosis of celiac disease, helping to prevent complications through dietary management. It is often recommended for individuals with gastrointestinal symptoms or related autoimmune conditions."
Test Parameters & Specifications
Sample Stability
- Hemolyzed or lipemic samples
- Insufficient sample volume
- Improperly labeled or collected specimens
Understanding Your Results
Negative
IgG antibody levels are within normal range; celiac disease is less likely but not excluded.
Positive
Elevated IgG antibody levels; suggests possible celiac disease or gluten sensitivity. Further diagnostic workup is recommended.
Equivocal
Borderline levels; repeat testing or additional tests may be needed for clarification.
If you experience persistent gastrointestinal symptoms such as abdominal pain, bloating, diarrhea, or unexplained weight loss after consuming gluten-containing foods, consult a gastroenterologist for evaluation and testing.
Limitations
- ⚠This test alone is not diagnostic; it should be used in conjunction with other celiac disease serology tests and clinical evaluation
- ⚠Negative results do not completely rule out celiac disease, especially in IgA-deficient individuals
- ⚠Results may be affected by gluten-free diet adherence prior to testing
Risks & Considerations
- ●Minor bruising or swelling at the blood draw site
- ●Rarely, dizziness or infection
Interfering Factors
- ●Recent consumption of gluten-containing foods may affect results
- ●Immunosuppressive medications can lower antibody levels
- ●False positives may occur in other autoimmune conditions
