Use

This test is useful for establishing a diagnosis of an allergy to red top and for defining the specific allergen responsible for eliciting allergy signs and symptoms. It helps identify allergens responsible for allergic responses or anaphylactic episodes, confirming sensitization before starting immunotherapy, and investigating the specificity of allergic reactions to various allergens such as insect venom, drugs, or chemicals. IgE antibody testing is not useful for assessing residual clinical sensitivity in patients treated with immunotherapy or in those where allergen identification is not required for medical management.
