Acarus siro, IgE, Serum
Use
Establishing the diagnosis of an allergy to Acarus siro (flour mites) and defining the allergen responsible for eliciting signs and symptoms. It aids in identifying allergens responsible for allergic response and/or anaphylactic episode, confirming sensitization prior to immunotherapy, and investigating the specificity of allergic reactions to insect venom allergens, drugs, or chemical allergens. Useful for understanding the patient’s allergic profile and directing appropriate therapeutic interventions.
Special Instructions
For a listing of allergens available for testing, refer to the Allergens - Immunoglobulin E (IgE) Antibodies PDF document. If not ordering electronically, complete, print, and send an Allergen Test Request Form (T236) with the specimen.
Limitations
Testing for IgE antibodies is not useful in patients previously treated with immunotherapy to determine if residual clinical sensitivity exists or in patients whose medical management does not depend upon identification of allergen specificity. False-positive results for IgE may occur in patients with elevated serum IgE due to nonspecific binding. Some individuals might show measurable levels of IgE antibodies despite clinically insignificant sensitivity.
