Buckwheat, IgE, Serum
Use
This test is used for establishing a diagnosis of an allergy to buckwheat, defining the allergen responsible for eliciting signs and symptoms, and identifying allergens responsible for an allergic response and/or anaphylactic episode. It also helps in confirming sensitization prior to beginning immunotherapy and investigating the specificity of allergic reactions to insect venom allergens, drugs, or chemical allergens. In vitro serum testing for IgE antibodies provides an indication of the immune response to allergens potentially associated with allergic disease.
Special Instructions
Not provided.
Limitations
The test must be interpreted within the clinical context. 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.
