Cherry, IgE, Serum
Use
This test is useful for establishing a diagnosis of an allergy to cherry and defining the allergen responsible for eliciting signs and symptoms. It helps identify allergens responsible for allergic responses and to confirm sensitization prior to beginning immunotherapy. It can also be used to investigate the specificity of allergic reactions to insect venom allergens, drugs, or chemical allergens.
Special Instructions
Not provided.
Limitations
The test is not useful for patients previously treated with immunotherapy to determine if residual clinical sensitivity exists, or in patients whose medical management does not depend upon identification of allergen specificity. False-positive results for IgE antibodies may occur in patients with markedly elevated serum IgE due to nonspecific binding. Test results must be interpreted within the clinical context, as some individuals may have measurable levels of IgE antibodies with clinically insignificant sensitivity.
