Cladosporium, IgE, Serum
Use
This test is used for establishing a diagnosis of an allergy to Cladosporium. It helps in defining the allergen responsible for eliciting signs and symptoms and identifying allergens responsible for allergic response and/or anaphylactic episodes. It is also used to confirm sensitization prior to beginning immunotherapy and to investigate the specificity of allergic reactions to insect venom allergens, drugs, or chemical allergens.
Special Instructions
For a listing of allergens available for testing, see 'Allergens - Immunoglobulin E (IgE) Antibodies'. If not ordering electronically, complete and send an 'Allergen Test Request' with the specimen. The test involves the use of Serum gel or Red top tubes, with submission in a plastic vial.
Limitations
Testing for IgE antibodies is not useful in patients previously treated with immunotherapy to determine if residual clinical sensitivity exists or in cases where medical management does not rely on identifying allergen specificity. Some individuals may have measurable levels of IgE antibodies despite clinically insignificant sensitivity, and false-positive results may occur in patients with elevated serum IgE due to nonspecific binding.
