Melaleuca leucadendron, IgE, Serum
Use
This test is useful for establishing a diagnosis of an allergy to Melaleuca leucadendron. It aids in identifying allergens responsible for allergic responses or anaphylactic episodes, confirming sensitization before immunotherapy, and investigating the specificity of allergic reactions to insect venom allergens, drugs, or chemical allergens. Detection of IgE antibodies in serum indicates an increased likelihood of allergic disease and defines the allergens that may be responsible for eliciting signs and symptoms.
Special Instructions
If not ordering electronically, complete and send an Allergen Test Request form with the specimen. For more information on the available allergens for testing, refer to the Allergens - Immunoglobulin E (IgE) Antibodies guide.
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 rely on identifying allergen specificity. Some individuals may have measurable levels of IgE antibodies without clinical significance, and results must be interpreted in the clinical context. False-positive results can occur in patients with markedly elevated serum IgE due to nonspecific binding to allergen solid phases.
