Rape Seed, IgE, Serum
Use
This test is useful for establishing the diagnosis of an allergy to rape seed, defining the allergen responsible for eliciting signs and symptoms, identifying allergens responsible for allergic responses and/or anaphylactic episodes. It can help confirm sensitization prior to starting immunotherapy and investigate the specificity of allergic reactions to insect venom allergens, drugs, or chemical allergens.
Special Instructions
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.
Limitations
Some individuals might have measurable levels of IgE antibodies even with clinically insignificant sensitivity to allergens. Test results should be interpreted within the clinical context. False-positive results for IgE antibodies could happen in patients with significantly elevated serum IgE (>2500 kU/L) due to nonspecific binding to allergen solid phases.
