Dermatophagoides microceras, IgE, Serum
Use
This test is useful for establishing a diagnosis of an allergy to Dermatophagoides microceras and helps define the allergen responsible for eliciting signs and symptoms. It identifies allergens responsible for an allergic response or anaphylactic episode, confirms sensitization before starting immunotherapy, and investigates the specificity of allergic reactions to insect venom allergens, drugs, or chemical allergens. It is not useful for patients previously treated with immunotherapy or when medical management does not depend on the identification of allergen specificity.
Special Instructions
Not provided.
Limitations
Testing for IgE antibodies is not recommended in patients previously treated with immunotherapy to check for residual clinical sensitivity or when the medical management does not rely on identifying allergen specificity. False positives can occur in patients with markedly elevated serum IgE (>2500 kU/L) due to non-specific binding.
