Use

Testing for IgE antibodies is useful for establishing a diagnosis of an allergy to lamb. It helps in defining the specific allergen responsible for eliciting signs and symptoms, identifying allergens responsible for allergic responses and/or anaphylactic episodes, confirming sensitization before immunotherapy, and investigating the specificity of allergic reactions to insect venom allergens, drugs, or chemical allergens. However, it is not useful in patients previously treated with immunotherapy to determine residual clinical sensitivity or in those whose medical management doesn't depend on allergen specificity identification.
