Test Code SEAFP Seafood Allergen Profile, Serum

Reporting Name

Seafood Allergen Profile

Useful For

Establishing a diagnosis of an allergy to seafood (cod, crab, lobster, shrimp, or tuna)

 

Defining the allergen responsible for eliciting signs and symptoms

 

Identifying allergens:

-Responsible for allergic response 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

 

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