Diagnosing hives and angioedema

Your doctor will need to ask many questions in an attempt to find the possible cause of hives or angiodema.

  • Since there are no specific tests for hives -- or the associated swelling of angioedema -- testing will depend on your medical history and a thorough examination by your primary care doctor, allergist, immunologist, or dermatologist.
  • Skin tests may be performed to determine the substance that you are allergic to. Routine blood tests are done to determine if a system-wide illness is present.
