Rye Food IgG4 details
What Rye Food IgG4 shows
This test measures IgG4 antibodies to rye grain proteins in your blood. IgG4 is a type of antibody the body commonly makes in response to foods you eat regularly, so a detectable level mainly reflects exposure and tolerance rather than allergy. Some people use food IgG4 results when exploring food-related symptoms, but their link to symptoms is debated, and major allergy organizations do not recommend them for diagnosing food allergy or intolerance. A higher result does not show that the food is causing your symptoms. This test is different from IgE testing, which looks for allergic sensitization. It also does not test for celiac disease.
