Understanding Your Results

Results indicate the level of deamidated gliadin IgA antibodies, which help assess immune response to gluten.
📊

Negative (< 20 U/mL)

No significant antibody detected; celiac disease is less likely, but clinical correlation is advised.

📊

Positive (≥ 20 U/mL)

Elevated antibodies suggest an immune response to gluten, indicative of celiac disease. Further testing, such as biopsy, is recommended for confirmation.

⚠️ When to Consult a Doctor:

If you experience persistent gastrointestinal symptoms, have a family history of celiac disease, or receive a positive test result, consult a gastroenterologist for further evaluation and management.

Limitations

  • ⚠A positive result does not confirm celiac disease; intestinal biopsy is often required for definitive diagnosis
  • ⚠May not detect celiac disease in individuals with IgA deficiency
  • ⚠Not suitable as a standalone screening test without clinical correlation

Risks & Considerations

  • ●Minor bruising or soreness at the puncture site
  • ●Rare risk of infection or dizziness

Interfering Factors

  • ●Recent gluten consumption may affect antibody levels
  • ●Immunoglobulin A deficiency can lead to false negatives
  • ●Certain medications or conditions may influence results

Frequently Asked Questions

What is the Gliadin Deamidated Antibody IgA Test?
It is a blood test that measures deamidated gliadin IgA antibodies to help diagnose celiac disease, an autoimmune disorder caused by gluten ingestion.
Why is this test recommended?
It is recommended for individuals with symptoms like abdominal pain, diarrhea, or fatigue, or for those at higher risk due to family history or genetic syndromes.
How is the test performed?
A blood sample is drawn from your arm and analyzed using enzyme immunoassay to detect antibody levels.
What do the results mean?
A positive result indicates elevated antibodies, suggesting celiac disease. A negative result makes it less likely, but clinical evaluation is essential.
Is fasting required for this test?
No, no special preparation or fasting is required. You can eat and drink normally before the test.
What is the cost of the test?
The test costs INR 1989 at DNA Labs India, with free home sample collection available across India.

What are the symptoms of celiac disease?
Symptoms include abdominal pain, bloating, diarrhea, constipation, fatigue, weight loss, iron-deficiency anemia, and mouth ulcers.
How accurate is the test?
The test has high sensitivity and specificity for detecting celiac disease, but a positive result typically requires confirmation with a biopsy.
What if my test result is positive?
Consult a gastroenterologist for further evaluation, which may include an intestinal biopsy and dietary guidance.
Can this test diagnose celiac disease alone?
No, it is a diagnostic aid. A positive result should be followed by additional tests for definitive diagnosis.
Who should get this test?
Individuals with symptoms of celiac disease, those with a family history, or people with associated conditions like Down syndrome or autoimmune disorders.
