Testing is not useful in patients previously treated with immunotherapy to determine if residual clinical sensitivity exists. False-positive results may occur in patients with markedly elevated serum IgE (>2500 kU/L) due to nonspecific binding to allergen solid phases. Allergen results of 0.10-0.34 kU/L are intended for specialist use as the clinical relevance is undetermined.
IgE levels may not correlate with clinical response or physiologic response on specific allergen challenge. The correlation of allergen laboratory results with clinical history and in vivo reactivity to specific allergens is essential. A negative test may not rule out clinical allergy or even anaphylaxis.
