Chub Mackerel, IgE, Serum
Use
This test is useful for establishing a diagnosis of an allergy to chub mackerel by detecting IgE antibodies in serum. It helps define the allergen responsible for eliciting signs and symptoms, identify allergens responsible for allergic response or anaphylactic episodes, confirm sensitization before beginning immunotherapy, and investigate the specificity of allergic reactions to insect venom allergens, drugs, or chemical allergens.
Special Instructions
For a listing of allergens available for testing, see Allergens - Immunoglobulin E (IgE) Antibodies PDF. 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 on identifying allergen specificity. Some individuals with clinically insignificant sensitivity to allergens may have measurable levels of IgE antibodies. False-positive results may occur in patients with markedly elevated serum IgE due to nonspecific binding.
