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
Not provided.
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.
