Allergy testing can determine whether allergic sensitivities are causing eczema. At our clinic, we would evaluate for a food allergy trigger with eczema under the following conditions:
- The patient has moderate-to-severe eczema.
- The patient has uncontrolled eczema despite appropriate aggressive management.
- The patient has a history compatible with IgE-mediated food allergy (eg. hives, vomiting, eczema flares after consuming specific foods).
This evaluation typically includes a detailed history, physical exam, skin or blood testing, and an elimination challenge diet.
Our companion site, Sinus & Allergy Center of the Midwest, provides more information on allergy testing.
