Papaya, IgE, Serum
Use
Establishing the diagnosis of an allergy to papaya. Defining the allergen responsible for eliciting signs and symptoms. Identifying 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. In vitro serum testing for IgE antibodies provides an indication of the immune response to allergens that may be associated with allergic disease.
Special Instructions
Not provided.
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.
