Respiratory Profile, Region 14, Central California, Serum
Use
This test is useful for assessing sensitization to various inhalant allergens commonly found in Central California, helping to define the allergen responsible for eliciting signs and symptoms. It aids in identifying allergens that are responsible for allergic responses 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
The test is not useful for patients who have previously undergone immunotherapy to determine residual clinical sensitivity, or when medical management does not depend upon allergen specificity. Ensure to complete and send an Allergen Test Request form (T236) with the specimen if not ordering electronically.
Limitations
This test does not provide useful results for patients who have been treated with immunotherapy or those where management does not depend on allergen identification. Elevated concentrations of total IgE are not solely diagnostic for allergic disease and must be considered in the context of patient history and clinical presentation. False positives may occur in cases with significantly elevated serum IgE due to nonspecific binding.
