Clove, IgE, Serum
Use
This test is useful for establishing the diagnosis of an allergy to clove. It helps in defining the allergen responsible for eliciting signs and symptoms and in identifying allergens responsible for allergic response and/or anaphylactic episode. The test can confirm sensitization prior to beginning immunotherapy and investigate 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 the medical management does not depend on allergen specificity identification.
Special Instructions
For the test, collect serum in a serum gel or red top container. Centrifuge and aliquot serum into a plastic vial. If not ordering electronically, complete, print, and send an Allergen Test Request (T236) with the specimen.
Limitations
Some individuals with clinically insignificant sensitivity to allergens may still have measurable levels of IgE antibodies in serum, and test results 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.
