The Gliadin Deamidated Peptide Antibody IgA test is a blood test used to diagnose coeliac disease and gluten-related autoimmune conditions like dermatitis herpetiformis (a skin-based complication of coeliac disease). It measures IgA antibodies against deamidated gliadin peptides (DGP), offering a more reliable and specific diagnostic marker than older gliadin antibody tests.

Coeliac disease is a chronic autoimmune condition where gluten consumption damages the small intestine, causing symptoms like bloating, diarrhoea, and nutrient deficiencies. This damage can lead to malnutrition, anaemia, and other significant health issues. The Gliadin Deamidated Peptide Antibody IgA test is recommended for individuals experiencing such symptoms or for those requiring dietary monitoring after switching to a gluten-free diet.

With superior diagnostic capabilities compared to traditional gliadin antibody tests, this test is also highly beneficial for screening individuals at risk, such as those with a family history of gluten-related conditions.

Residents of Delhi who wish to test for gluten intolerance or coeliac disease can schedule the Gliadin Deamidated Peptide Antibody IgA test at home, ensuring precise results and delivered quickly.

Preparing for the Gliadin Deamidated Peptide Antibody IgA test can be done easily at home with these simple guidelines:

• Prerequisites

Fasting is unnecessary for this test. Continue to consume gluten-containing foods for several weeks before the test for reliable and accurate results.

• Best Time to Get Tested

You can schedule the Gliadin Deamidated Peptide Antibody IgA test for any time during the day. 4

• Who Should Get a Gliadin Deamidated Peptide Antibody IgA Test?

This test is particularly recommended for individuals showing signs of coeliac disease, including prolonged diarrhoea, unexplained weight changes, or malnutrition. It’s also valuable for those following a gluten-free diet to evaluate dietary compliance and for people with a hereditary predisposition to coeliac disease or autoimmune conditions. 1

• Cautions Before Taking a Gliadin Deamidated Peptide Antibody IgA Test

Before taking this test, inform about any medications you’re on or health conditions you have with your doctor to avoid inaccurate results.

The Gliadin Deamidated Peptide Antibody test is important for diagnosing coeliac disease. It evaluates intestinal damage, tracks response to treatment, and monitors adherence to a gluten-free diet.

Consider taking this test if you:

• Experience digestive problems like nausea, vomiting, diarrhoea, constipation, gas, bloating, or unexplained weight fluctuations.

• Have non-digestive symptoms such as depression, fatigue, headaches, anxiety, skin rashes, or irritability (in children).

• Have a family history of coeliac disease or autoimmune disorders such as type 1 diabetes.

• Are diagnosed with coeliac disease and need to verify compliance with a gluten-free diet.

• Require early detection of coeliac disease, even in the absence of symptoms, if risk factors are present.

Coeliac disease differs from gluten sensitivity or wheat allergies, as it results in permanent intestinal damage, highlighting the need for early detection and lifelong management.
