Coriander, IgE, Serum
Use
Establishing the diagnosis of an allergy to coriander and defining the allergen responsible for eliciting signs and symptoms. It is useful for identifying allergens responsible for allergic response and/or anaphylactic episodes, and confirming sensitization prior to beginning immunotherapy. It also helps in 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 in whom the medical management does not depend upon identification of allergen specificity.
Special Instructions
Ensure proper specimen collection and handling. If not ordering electronically, complete, print, and send an Allergen Test Request form (T236) with the specimen.
Limitations
Some individuals with clinically insignificant sensitivity to allergens may have measurable levels of IgE antibodies in serum, leading to potential false positives. The test results must be interpreted within the clinical context, especially for patients with markedly elevated serum IgE (>2500 kU/L) due to nonspecific binding to allergen solid phases.
