Mulberry, IgE, Serum
Use
The test is useful for establishing a diagnosis of an allergy to mulberry and defining the allergen responsible for eliciting signs and symptoms. It aids in identifying allergens responsible for allergic response and/or anaphylactic episodes. Additionally, it confirms sensitization prior to beginning immunotherapy and investigates the specificity of allergic reactions to insect venom allergens, drugs, or chemical allergens.
Special Instructions
Not provided.
Limitations
Testing for IgE antibodies is not useful in patients previously treated with immunotherapy to determine if residual clinical sensitivity exists or in patients in whom the medical management does not depend upon identification of allergen specificity. False-positive results for IgE antibodies may occur in patients with markedly elevated serum IgE (>2500 kU/L) due to nonspecific binding to allergen solid phases. Results must be interpreted in clinical context.
