Respiratory Profile, Region 11, Rocky Mountain (AZ [Mt]; CO; ID [Mt]; NM, UT [Mt]; WY), Serum
Use
The test is useful for assessing sensitization to various inhalant allergens commonly found in the Rocky Mountain region including Arizona, Colorado, Idaho, New Mexico, Utah, and Wyoming. It helps in defining the allergen responsible for eliciting signs and symptoms, identifying allergens responsible for allergic response or anaphylactic episodes, confirming sensitization prior to beginning immunotherapy, and investigating the specificity of allergic reactions to insect venom allergens, drugs, or chemical allergens.
Special Instructions
This test is not useful for patients previously treated with immunotherapy to determine if residual clinical sensitivity exists or in whom the medical management does not depend upon identification of allergen specificity.
Limitations
Total IgE measurements have limited utility for diagnostic evaluation of patients with suspected allergic disease, and should be interpreted in the clinical context. An elevated concentration of total IgE is not diagnostic for allergic disease. 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. Normal IgE levels do not rule out allergic disease and significant sensitizations may still exist.
