Coffee (f221) IgG details
What Coffee (f221) IgG shows
This test measures IgG antibodies to coffee as part of a food-specific IgG panel. Food-specific IgG panels are used by some practitioners to look at your immune response to foods in your diet. A higher result generally means you have been exposed to coffee, often through regular drinking, while a low result may reflect little recent intake. Food IgG reflects exposure rather than allergy, its link to symptoms is debated, and it is not a test for a true food allergy, which is assessed with IgE.
Tests that include Coffee (f221) 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].
