FOOD6 FOOD6-Food Panel LAB0291443 ALLERGEN, FOOD PROFILE, IGE

Reporting Name

Food Panel

Useful For

Establishing a diagnosis of an allergy to codfish, cow's milk, egg white, peanut, soybean, and wheat 

 

Defining the allergen responsible for eliciting signs and symptoms

 

Identifying allergens:

-Responsible for allergic response 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.

 

Testing Algorithm

Includes testing for codfish, cow's milk, egg white, peanut, soybean, and wheat allergen.

Method Name

Fluorescence Enzyme Immunoassay (FEIA)

Performing Laboratory

Mayo Clinic Laboratories in Rochester

Specimen Type

Serum


Ordering Guidance


This test uses a pooled allergen reagent; therefore, the multi-allergen Immunocap (panel cap) is reported with a single qualitative class result and concentration. This is the appropriate first-tier test for allergic disease.

 

For a listing of allergens available for testing, see Allergens - Immunoglobulin E (IgE) Antibodies
