GLIADIN ANTIBODY IGG TEST (Celiac Disease)
(Flat ₹301 OFF - Sanovra Lab)
Report Time: Next Day Evening | Sample: Blood (Serum) | Days: Except Sunday
Gliadin Antibody IgG is a blood test used to detect the body's immune reaction to Gluten (a protein found in wheat, barley, and rye). While the IgA test is the standard for Celiac Disease, the IgG test is critical for patients who have an IgA Deficiency, a condition common among Celiac patients.
This test helps identify Celiac Disease and Non-Celiac Gluten Sensitivity (NCGS) in individuals whose immune systems do not produce enough IgA antibodies, ensuring that a diagnosis is not missed.
IgG vs IgA: Why Do We Need Both?
Celiac Disease diagnosis can be tricky. Here is why the IgG test is important:
-
✔The Standard (IgA): Usually, the body fights gluten in the gut using IgA antibodies. This is the first line of defense.
-
✔The Problem (IgA Deficiency): About 2-3% of Celiac patients cannot make IgA antibodies at all. If we only test them for IgA, the result will be Negative even if they have severe Celiac disease.
-
✔The Solution (IgG): The IgG test acts as a backup. It detects antibodies in the bloodstream. If a patient is IgA deficient but has Celiac, the IgG test will often be Positive.
Who Should Take This Test?
This test is specifically recommended for:
-
➤Patients who tested negative for IgA antibodies but still have strong symptoms of gluten intolerance.
-
➤Children under the age of 2 (whose IgA systems may not be fully developed).
-
➤Individuals with known selective IgA deficiency.
Important: The Gluten Rule
Recommendation: Do not stop eating wheat/gluten until after your blood test is complete.
Interpreting Your Results
| Result | Interpretation |
|---|---|
| Positive (Elevated) | Indicates an immune reaction to gluten. In the presence of IgA deficiency, this strongly suggests Celiac Disease. In others, it may indicate Non-Celiac Gluten Sensitivity. |
| Negative (Normal) | No IgG antibodies detected. Unlikely to have Celiac Disease (provided you were eating gluten). |
Frequently Asked Questions (FAQs)
Celiac Disease is an autoimmune condition where gluten damages the intestine. Gluten Sensitivity causes symptoms (bloating, brain fog) but does not damage the intestine. High IgG can sometimes be seen in both.
No, fasting is not required. You can eat and drink normally before the test.
No, the Gliadin IgG test is processed on all days Except Sunday at Sanovra Lab.
