About the test
This test is crucial for diagnosing celiac disease by detecting antibodies against gliadin, a key protein in gluten. While gliadin antibodies can appear in people without celiac disease, making the test less specific, recent advancements have improved its accuracy. The test now focuses on deamidated gliadin peptides, which have a stronger reaction with antibodies in celiac patients, offering a more precise diagnosis compared to traditional gliadin antibody tests.
Who might consider it:
This test is particularly useful for individuals showing symptoms of celiac disease or those with a family history of the condition.
Common Symptoms of Celiac Disease:
- Stomach pain
- Bloating
- Diarrhea or constipation
- Anemia
- Weight loss
- Feeling tired all the time
