CertifiedLabsWhat is Anti Gliadin Deamidated Peptide antibody IgG Test?
The Gliadin Deamidated Peptide Antibody IgG test detects gliadin antibodies in the blood, helping diagnose coeliac disease or gluten sensitivity. Coeliac disease is an autoimmune disorder where the gluten in foods like wheat, barley and rye triggers an immune system attack on the small intestine. This impairs nutrient absorption as it damages the small intestinal villi (tiny, finger-like projections) that help absorb nutrients from food. This can lead to symptoms such as weight loss, stomach pain, fatigue, weak bones, and anaemia.
A positive IgG result may require further testing, including a small intestine biopsy, to confirm the diagnosis.
Coeliac disease can develop at any age but is most commonly diagnosed in infants (8–12 months) or adults (40–60 years). Many individuals remain undiagnosed due to mild or unclear symptoms. Those with a family history of the condition or other autoimmune diseases should consider testing, even if they have no symptoms.
Individuals residing in Bangalore can consider getting a Gliadin Deamidated Peptide Antibody IgG test at home for detecting gluten-related immune reactions.
Anti Gliadin Deamidated Peptide antibody IgG Test Parameters
The Gliadin Deamidated Peptide Antibody IgG test measures a single parameter: the presence of immunoglobulin G (IgG) antibodies against gliadin.
There are two Gliadin Deamidated Peptide Antibody tests: IgG and IgA. IgA is more commonly used since it is produced in the intestine, but IgA-deficient individuals may get false-negative results. To improve the accuracy of the results, IgG testing is often done alongside IgA.
Newer tests like the Tissue Transglutaminase IgA (tTG-IgA) test are more accurate, but about 2% of coeliac patients lack IgA antibodies, making this test ineffective for them. To avoid misdiagnosis, total IgA levels are checked, and DGP-IgG is used, as it remains reliable in IgA-deficient individuals. While an IgG tTG test exists, it is less reliable than DGP-IgG. IgG and IgA antigliadin tests can also help diagnose gluten-related neurological disorders.
Anti Gliadin Deamidated Peptide antibody IgG Test Preparation
To get ready for the Gliadin Deamidated Peptide Antibody IgG test at home, make sure to follow these simple steps:
Prerequisites : Deamidated Peptide Antibody IgG test.
Best Time to Get Tested :
The Gliadin Deamidated Peptide Antibody IgG test can be done at any time of the day, without restrictions on timing.
Who Should Get a Gliadin Deamidated Peptide Antibody IgG Test? : People with digestive issues, unexplained weight loss, nutrient deficiencies, autoimmune disorders, or coeliac disease symptoms like diarrhoea, bloating, fatigue, or rashes should take this test.
Cautions Before Taking a Gliadin Deamidated Peptide Antibody IgG Test : No special precautions are required for the test, but maintaining a regular diet that includes gluten is essential. Because if you stop eating gluten for several weeks before testing, your antibody levels may appear normal even if you have coeliac disease.
Why Take the Anti Gliadin Deamidated Peptide antibody IgG Test?
You might need a Gliadin Deamidated Peptide Antibody IgG test if you have symptoms of coeliac disease, which can differ from person to person. Some common symptoms of coeliac disease include:
Frequent diarrhoea
Stomach pain and bloating
Unexplained weight loss
Gas and constipation
Pale, greasy, or bad-smelling poop
Mouth sores
Itchy skin rashes
Feeling tired all the time
Tingling or numbness in your hands and feet
Feeling anxious or sad often
Even if you do not have these symptoms, this test may still be needed if your body is not absorbing enough nutrients like iron, folate, vitamin B12, calcium, or vitamin D.
People with conditions like type 1 diabetes, Down syndrome, or other genetic disorders are more likely to have coeliac disease. Frequent headaches, trouble growing, and difficulty getting pregnant may also require them to take the test.
