Updated Test Information:
Walnut (Tree) IgE
An allergen is a type of antigen that initiates an immune response. After this initiation, also called sensitization, an allergic individual will produce IgE against that allergen. Specific IgE can be used to determine allergen sensitization, potential anaphylaxis response, and aid in disease management. Assay results should be used in conjunction with clinical findings and other serological tests.
