Updated Test Information:
Milk IgE, Reflex to Components
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. Testing the individual components of an allergen, referred to as component resolved diagnosis (CRD), improves the predictive value for determining severity of allergen sensitization. Assay results should be used in conjunction with clinical findings and other serological tests.
