Soybean (f14) IgG details
What Soybean (f14) IgG shows
This test measures IgG antibodies to soybean proteins in your blood. Soy is common in processed foods, plant milks, tofu, sauces and many packaged products, so most people meet it regularly. Food IgG tests are sometimes ordered to look at reactions to foods that are not immediate allergies. A higher result generally reflects exposure — your immune system has seen soy — and often simply tracks how much you eat. A low result usually means little recent exposure. The link between food IgG and symptoms is debated, and IgG does not measure a true soy allergy, which is assessed with IgE testing and your history.
Tests that include Soybean (f14) IgG
IgE-assays are the best-studied and most accepted serologic tests for evaluating food allergy status. However, some clinicians also use IgG tests when evaluating individuals for food allergies, sensitivities, or tolerance. Food-specific IgG is generally believed to be a normal physiological response to food exposures. Therefore, many professional organizations, including the American Academy of Allergy, Asthma & Immunology, the Canadian Society of Allergy and Clinical Immunology, and the European Academy of Allergy and Clinical Immunology, recommend against using IgG testing to diagnose food allergies or food intolerances/sensitivities [1-3].
