Reference Range

Allergy Reference Range: Less than 0.35 kU/L.

Range (kU/L) Class Interpretation
≤ 0.34 0 Negative
0.35-0.69 1 Low
0.70-3.49 2 Medium
3.50-17.49 3 High

Test Methodology

Fluorescence Enzyme Immunoassay (FEIA).

Interpretation

The allergen class may not be predictive of clinical disease in some patients. The diagnosis of allergy should be based upon patient history and clinical findings. The diagnosis of allergy should not be based upon laboratory findings alone.

Clinical Utility

A positive test result (class 1 or greater) is indicative of the presence of allergen-specific IgE and suggests an increased likelihood of allergic disease.
