What tests will be done to diagnose ear eczema?

Your healthcare provider can typically diagnose ear eczema after a physical exam. However, if there’s any doubt, they may perform the following tests:

• An allergy skin test.
• Blood tests to check for causes of a rash that might be unrelated to ear eczema.
• A skin biopsy to distinguish one type of dermatitis from another.
