Test ID PERS Persimmon, IgE, Serum

Useful For

Establishing the diagnosis of an allergy to Persimmon, IgE

 

Defining the allergen responsible for eliciting signs and symptoms

 

Identifying allergens:

- Responsible for allergic disease and/or anaphylactic episode

- To confirm sensitization prior to beginning immunotherapy

- To investigate the specificity of allergic reactions to insect venom allergens, drugs, or chemical allergens

 

Testing for IgE antibodies is not useful in patients previously treated with immunotherapy to determine if residual clinical sensitivity exists, or in patients in whom the medical management does not depend upon identification of allergen specificity.
