Northeast Regional Allergen Profile, Serum
Use
The Northeast Regional Allergen Profile is used to establish the diagnosis of an allergy to Northeast regional allergens. It helps in defining the specific allergens responsible for eliciting signs and symptoms in the patient. The test is also useful for identifying allergens responsible for allergic responses or anaphylactic episodes, confirming sensitization before starting immunotherapy, and investigating the specificity of allergic reactions to insect venom allergens, drugs, or chemical allergens. This test is not suitable for patients who have undergone immunotherapy to determine if residual clinical sensitivity exists or in cases where medical management does not rely upon identification of allergen specificity.
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.
