Specimen Type
SerumOrdering 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.

Method Name
Fluorescence Enzyme Immunoassay (FEIA)
Testing Algorithm
Includes testing for Alternaria tenuis, Aspergillus fumigatus, Candida albicans (monilia), Cladosporium herbarum, Helminthosporium halodes, and Penicillium chrysogenum allergen.
Useful For
Establishing a diagnosis of an allergy to mold
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.
