FDA Status
This test was performed using a kit that has not been cleared or approved by the FDA. The analytical performance characteristics of this test have been determined by Quest Diagnostics. This test, and any food specific allergen IgG result, should not be used for the diagnosis of allergic or atopic disease states (except for sensitivity to milk in neonates and gluten sensitivity). The use of food specific allergen IgG results should be restricted to the assessment of response to therapeutic interventions.
Setup Schedule
Set up: Mon-Sat; Report available: 1-3 days
Clinical Significance
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].
We offer IgG food tests to support providers who use them in their evaluation of patients experiencing adverse reactions to foods.
