what does positive iga means
This is how to interpret what these gliadin antibodies mean: A positive old test (IgG-gliadin antibody) usually means gluten sensitivity. A positive new test (DGP-IgG and DGP-IgA) means celiac disease. A negative old test usually means that gluten is unlikely to be a problem. A negative new test means that celiac disease is unlikely at the time of the test, but it does not rule out gluten sensitivity. As you can see, there is gliadin antibody confusion. The same name is being used for both tests, but they have different interpretations.
