Cauliflower, IgE, Serum
Use
This test is useful for establishing the diagnosis of an allergy to cauliflower and defining the specific allergen responsible for eliciting signs and symptoms. It helps identify allergens that are responsible for allergic responses and/or anaphylactic episodes. Additionally, it can confirm sensitization prior to the beginning of 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 whose medical management does not depend upon identification of allergen specificity.
Special Instructions
For a listing of allergens available for testing, see the Allergens - Immunoglobulin E (IgE) Antibodies documentation. 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 have measurable levels of IgE antibodies in serum. False-positives for IgE antibodies may occur in patients with markedly elevated serum IgE (>2500 kU/L) due to nonspecific binding to allergen solid phases. Test results must be interpreted in the clinical context. The test is not cleared or approved by the US FDA.
