Salmon (f41) IgG4 details
What Salmon (f41) IgG4 shows
This test measures IgG4 antibodies to salmon 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.
