IgG Food Antibodies

The IgG Food Antibody Assessment (*not available in NY) is a blood test that measures antibodies to 87 commonly consumed foods. The panel also includes a total IgE measurement. The body can react to foods in many different ways. Adverse food reactions can lead to distressing symptoms and chronic health conditions. Often times it is unknown exactly which food(s) may be the cause and testing can help identify the problematic foods. Removal of the reactive foods often results in resolution of symptoms. When should testing for IgG Food Antibodies be considered?
Testing for adverse food reactions is useful for individuals who suspect that a food is responsible for causing their symptoms, but can't quite identify which food(s). The presence of circulating antibodies may affect each patient differently. Circulating IgG food antibodies are not diagnostic for a specific condition, but indicate an immune response to that food. The immune response could be a normal response that would not necessarily cause symptoms. Therefore, test results should always be viewed in the context of the overall clinical picture. The role of IgG food antibody testing is still being researched, however, studies have shown the benefit of testing in certain conditions.1
