Acacia, IgE, Serum
Use
This test is useful for establishing the diagnosis of an allergy to acacia by measuring the level of specific IgE antibodies in the serum. It defines the allergen responsible for eliciting signs and symptoms and identifies allergens responsible for allergic responses and/or anaphylactic episodes. It 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 listing of allergens available for testing, refer to the Allergens - Immunoglobulin E (IgE) Antibodies PDF. If not ordering electronically, complete, print, and send an Allergen Test Request (T236) with the specimen.
Limitations
Testing for IgE antibodies is not useful in patients previously treated with immunotherapy to determine if residual clinical sensitivity exists or in patients whose medical management does not depend upon identification of allergen specificity. Some individuals with clinically insignificant sensitivity may have measurable levels of IgE antibodies. False-positive results may occur in patients with elevated serum IgE due to nonspecific binding.
