Queen Palm, IgE, Serum
Use
The test is useful for establishing a diagnosis of an allergy to queen palm by identifying the specific allergens responsible for triggering allergic responses or anaphylactic episodes. It confirms sensitization prior to starting immunotherapy and investigates the specificity of allergic reactions to insect venom allergens, drugs, or chemical allergens. Additionally, the presence of IgE antibodies in serum is indicative of an increased likelihood of allergic disease and helps define allergens that may be responsible for causing clinical symptoms.
Special Instructions
The test should not be used to determine if residual clinical sensitivity exists in patients who have been previously treated with immunotherapy, or in situations where medical management does not depend on identifying allergen specificity. If not ordering electronically, complete, print, and send an Allergen Test Request (T236) with the specimen.
Limitations
Some individuals may possess detectable levels of IgE antibodies without significant clinical sensitivity to allergens, leading to potential false-positive results. Additionally, patients with markedly elevated serum IgE (>2500 kU/L) might also display false-positive results due to nonspecific binding to allergen solid phases. These factors necessitate interpreting test results within a clinical context.
