June Grass, IgE, Serum
Use
This test is used for establishing a diagnosis of an allergy to June grass. It helps define the allergen responsible for eliciting signs and symptoms of allergic responses such as respiratory diseases, anaphylactic episodes, or eczema. Specifically, it identifies allergens responsible for allergic responses and confirms sensitization prior to beginning immunotherapy, and investigates the specificity of allergic reactions to insect venom allergens, drugs, or chemical allergens.
Special Instructions
IgE antibody testing is not useful for patients previously treated with immunotherapy to determine if residual clinical sensitivity exists or in patients where medical management does not rely on allergen specificity identification.
Limitations
False-positive results for IgE antibodies may occur in patients with markedly elevated serum IgE greater than 2500 kU/L due to nonspecific binding to allergen solid phases. Some individuals with clinically insignificant sensitivity to allergens may have measurable levels of IgE antibodies in serum. Test results should be interpreted in the clinical context.
