Plaice, IgE, Serum
Use
The Plaice, IgE, Serum test is useful for establishing a diagnosis of an allergy to plaice and defining the allergen responsible for eliciting signs and symptoms. It also aids in identifying allergens responsible for allergic responses and/or anaphylactic episodes and is used to confirm sensitization prior to beginning immunotherapy. This test isn't useful in patients previously treated with immunotherapy to determine if residual clinical sensitivity exists, or in cases where medical management doesn't rely on allergen specificity.
Special Instructions
For patients not ordering electronically, complete the Allergen Test Request (T236) form and send it with the specimen. Consider patient history, age, allergen exposure, and clinical manifestations for choosing the appropriate allergens.
Limitations
Some individuals with clinically insignificant sensitivity to allergens may still have measurable levels of IgE antibodies, and results must be interpreted clinically. False-positive results may occur in patients with markedly elevated serum IgE (>2500 kU/L) due to nonspecific binding to allergen solid phases.
