Eucalyptus, IgE, Serum
Use
Establishes a diagnosis of an allergy to eucalyptus by identifying the presence of IgE antibodies specific to eucalyptus allergens. This test helps define the allergen responsible for eliciting signs and symptoms and confirms sensitization prior to immunotherapy. It is important for determining allergens responsible for allergic responses and anaphylactic episodes, as well as investigating 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 PDF. Complete and send an Allergen Test Request form (T236) if not ordering electronically.
Limitations
Testing for IgE antibodies is not useful in patients previously treated with immunotherapy to determine if residual clinical sensitivity exists or in patients for whom medical management does not rely on allergen specificity identification. False positives may occur in patients with markedly elevated serum IgE (>2500 kU/L) due to nonspecific binding.
