Skin testing, in vitro immunoglobulin E (IgE) tests, or both may be used to determine the stimulus causing the anaphylactic reaction. Such studies may include the following:

  • Testing for food allergy(ies)

  • Testing for medication allergy(ies)

  • Testing for causes of IgE-independent reactions
