Sugarbeet Seed, IgE, Serum
Use
This test is useful for establishing the diagnosis of an allergy to sugar beet seed. It helps define the allergen responsible for eliciting the signs and symptoms of an allergic response or anaphylactic episode. The test can confirm sensitization before starting immunotherapy and investigate the specificity of allergic reactions to various allergens, including insect venom, drugs, or chemicals. However, testing for IgE antibodies is not useful in patients previously treated with immunotherapy to determine if residual clinical sensitivity remains, nor in patients where medical management does not rely on allergen specificity.
Special Instructions
Complete an Allergen Test Request form (T236) if not ordering electronically. The test requires specialized handling and coordination as specified in the requisition forms and guidelines.
Limitations
Serum IgE antibody levels must be interpreted within the clinical context as false positives may occur in patients with significantly elevated IgE levels due to non-specific binding to allergen solid phases. Some individuals with low clinical sensitivity may still show measurable IgE antibody levels.
