Tilapia, IgE, Serum
Use
This test is useful for establishing the diagnosis of an allergy to tilapia by measuring specific IgE antibodies in patient serum. It helps define the allergen responsible for eliciting allergic reactions, including anaphylactic episodes, confirming sensitization prior to beginning immunotherapy, and investigating the specificity of allergic reactions to insect venom allergens, drugs, or chemical allergens. It is not useful in patients previously treated with immunotherapy to determine residual clinical sensitivity, or in cases where medical management does not depend on allergen identification.
Special Instructions
Orders should be accompanied by the Allergen Test Request form if not ordered electronically. For a listing of available allergens for testing, refer to the provided Allergens - Immunoglobulin E (IgE) Antibodies guide. Additionally, care should be taken in specimen collection and handling to avoid diagnostic confusion from improper procedures or conditions.
Limitations
Some individuals may have measurable levels of IgE antibodies without clinically significant sensitivity to allergens. False-positive results for IgE antibodies may occur in patients with markedly elevated serum IgE due to nonspecific binding. Test results must be interpreted in the clinical context. The test has not been cleared or approved by the FDA, although it was created in accordance with CLIA requirements.
