Pig Epithelium, IgE, Serum
Use
This test is used for establishing a diagnosis of an allergy to pig epithelium by identifying the specific allergen responsible for eliciting signs and symptoms. It helps to confirm sensitization prior to beginning immunotherapy and investigate the specificity of allergic reactions to other allergens. In vitro serum testing for IgE antibodies provides an indication of the immune response to allergens potentially associated with allergic disease. The results offer insight into the allergens responsible for allergic disorders and episodes, aiding in the management and treatment of allergic conditions.
Special Instructions
Not provided.
Limitations
Testing for IgE antibodies is not useful in patients who have been previously treated with immunotherapy for an allergy to pig to determine if residual clinical sensitivity exists. False positives may occur in patients with markedly elevated serum IgE (>2500 kU/L) due to non-specific binding to allergen solid phases. Results must be interpreted within the clinical context, as some individuals may have measurable levels of IgE antibodies in serum for allergens that are clinically insignificant.
