Seminal Fluid, IgE, Serum
Use
The test is useful for establishing the diagnosis of an allergy to seminal fluid and defining the allergen responsible for eliciting signs and symptoms. It identifies allergens responsible for allergic response and/or anaphylactic episode, to confirm sensitization prior to beginning immunotherapy, and to investigate the specificity of allergic reactions to insect venom allergens, drugs, or chemical allergens. 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
For a listing of allergens available for testing, see the Allergens - Immunoglobulin E (IgE) Antibodies document. 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, and test results must be interpreted in 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.
