HelpTest Code RPR4 Respiratory Profile, Region 4, Subtropic Florida (Florida S. of Orlando), Serum
Useful For
Assessing sensitization to various inhalant allergens commonly found in subtropic Florida, which is south of Orlando
Defining the allergen responsible for eliciting signs and symptoms
Identifying allergens:
-Responsible for allergic response or anaphylactic episode
-To confirm sensitization prior to beginning immunotherapy
-To investigate the specificity of allergic reactions to insect venom allergens, drugs, or chemical allergens
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.
