Pediatric Allergy Screen <3 Years, Serum
Use
This test is used to establish a diagnosis of an allergy to egg whites, milk, wheat, soybeans, and house dust mites. It helps define the allergen responsible for eliciting signs and symptoms and identifies allergens responsible for an allergic response or anaphylactic episode. This test is useful for confirming sensitization prior to starting immunotherapy and investigating the specificity of allergic reactions to insect venom allergens, drugs, or chemical allergens.
Special Instructions
This test is not useful for patients previously treated with immunotherapy to determine if residual clinical sensitivity exists, or in cases where medical management does not rely on identifying allergen specificity. If not ordered electronically, complete, print, and send an Allergen Test Request form with the specimen.
Limitations
Some individuals with clinically insignificant sensitivity to allergens may still have measurable levels of IgE antibodies. False-positive results can occur in patients with markedly elevated serum IgE (>2500 kU/L) due to nonspecific binding. Test results must be interpreted in the context of clinical history and symptomatology.
