Dog Dander, IgE, Serum
Use
This test is useful for establishing a diagnosis of an allergy to dog dander. It helps define the allergen responsible for eliciting signs and symptoms, and identifies allergens responsible for allergic response and/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. Testing for IgE antibodies is not useful in patients previously treated with immunotherapy to determine if residual clinical sensitivity exists, or in patients where medical management does not depend on identification of allergen specificity.
Special Instructions
If not ordering electronically, complete, print, and send an Allergen Test Request with the specimen. Refer to the allergen PDF for a listing of allergens available for testing.
Limitations
Some individuals with clinically insignificant sensitivity to allergens may still have measurable levels of IgE antibodies in serum. False-positive results for IgE antibodies may occur in patients with markedly elevated serum IgE (>2500 kU/L) due to nonspecific binding to allergen solid phases. Test results must be interpreted in the clinical context.
