Use

This test is useful for diagnosing an allergy to canary feathers by identifying IgE antibodies responsible for allergic responses and/or anaphylactic episodes. It helps in confirming sensitization before starting immunotherapy and in investigating the specificity of allergic reactions to various allergens, including insect venom, drugs, or chemical allergens. Testing IgE antibodies is not useful for patients who've received immunotherapy to evaluate residual sensitivity or for those whose management doesn't depend on allergen identification.
