Respiratory Profile, Region 7, Northern Midwest (MI, MN, WI), Serum
Use
This test is useful for assessing sensitization to various inhalant allergens commonly found in the Northern Midwest region, including Michigan, Minnesota, and Wisconsin. It helps define the allergen responsible for eliciting signs and symptoms and identify allergens responsible for allergic responses or anaphylactic episodes. It can confirm sensitization prior to beginning immunotherapy and investigate the specificity of allergic reactions to insect venom allergens, drugs, or chemical allergens.
Special Instructions
This test should not be used for patients previously treated with immunotherapy to determine if residual clinical sensitivity exists or for patients where medical management does not depend on the identification of allergen specificity. It is important to complete, print, and send an Allergen Test Request (T236) with the specimen if not ordering electronically.
Limitations
An elevated concentration of total IgE is not diagnostic for allergic disease. It must be interpreted in the clinical context of the patient, including age, sex, travel history, potential allergen exposure, and family history. A normal concentration of total IgE does not eliminate the possibility of 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.
