Note
Test methodology uses solid-phase immunoassays against the whole peanut allergen (f13) and 5 antigenic epitopes (Ara h1, Ara h2, Ara h3, Ara h8, and Ara h9) and measures IgE antibody concentrations in patient serum or plasma. The binding of a specific IgE to an immobilized allergen component is detected by the addition of a secondary fluorescence-labeled anti-human IgE antibody. This test has a cutoff of 0.1 KU/L.
