Non-Seasonal Inhalant Allergen Profile, Serum
Use
The Non-Seasonal Inhalant Allergen Profile test is useful for establishing a diagnosis of an allergy to non-seasonal inhalant allergen profiles. It helps define the allergens responsible for eliciting signs and symptoms and identifies allergens responsible for allergic response or anaphylactic episodes. This test can confirm sensitization prior to beginning immunotherapy and investigate the specificity of allergic reactions to insect venom allergens, drugs, or chemical allergens.
Special Instructions
For a list of available allergens for testing, refer to Allergens - Immunoglobulin E (IgE) Antibodies document. Submission requires centrifuging and aliquoting serum into a plastic vial. If not ordering electronically, complete and send an Allergen Test Request form (T236) with the specimen.
Limitations
This test is not useful for determining residual clinical sensitivity in patients previously treated with immunotherapy, or in patients where medical management does not depend on identifying allergen specificity. False-positive results may occur in patients with markedly elevated serum IgE (>2500 kU/L) due to nonspecific binding to allergen solid phases.
