Brussels Sprouts, IgE, Serum
Use
The test is useful for establishing the diagnosis of an allergy to Brussels sprouts and defining the allergen responsible for eliciting signs and symptoms. It helps in identifying allergens responsible for allergic responses and/or anaphylactic episodes, confirming sensitization prior to beginning immunotherapy, and investigating the specificity of allergic reactions to insect venom allergens, drugs, or chemical allergens. However, testing for IgE antibodies is not useful in patients previously treated with immunotherapy to determine if residual clinical sensitivity exists or in patients where medical management does not depend on identifying allergen specificity.
Special Instructions
Not provided.
Limitations
Some individuals with clinically insignificant sensitivity to allergens may have measurable levels of IgE antibodies in serum, which must be interpreted in the clinical context. False-positive results may occur in patients with markedly elevated serum IgE (>2500 kU/L) due to nonspecific binding to allergen solid phases. Testing is not useful for determining clinical sensitivity in individuals previously treated with immunotherapy or where medical management does not depend on allergen specificity.
