Diagnostic Use Or Instructions

The Choosing Wisely recommendations include the following:

Don’t perform unproven diagnostic tests, such as immunoglobulin G (IgG) testing or an indiscriminate battery of immunoglobulin E (IgE) tests, in the evaluation of allergy.

Food specific IgE testing should not be performed without a clinical history suggestive of IgE mediated food allergy.

IgE testing is indicated when there is a suspicion of an allergic reaction; the suspected allergen should be identified by detailed history and specified for testing. Indiscriminate batteries of IgE tests for foods are expensive and not useful, potentially leading to erroneous diagnoses and inappropriately restrictive diets.
