Details
Food Specific IgG Allergy (Pediatric) Panel - 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. Quest offers IgG food tests to support providers who use them in their evaluation of patients experiencing adverse reactions to foods.

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].
