Unit
kU/L

This measures the concentration of IgE antibodies directed specifically against peanut proteins (e.g., Ara h 1, 2, 3). In an Allergy Profile, this identifies sensitization. High levels are strongly associated with Type I hypersensitivity, including the risk of life-threatening anaphylaxis upon exposure.

Why Context Matters

A positive IgE test indicates 'sensitization', not necessarily 'clinical allergy'. Many patients test positive but can eat peanuts without symptoms (cross-reactivity with birch pollen/legumes). A second opinion might involve component-resolved diagnostics (CRD) or an oral food challenge.

Lab ranges are statistical averages, not biological laws. "Normal" for a 20-year-old male isn't normal for a 60-year-old female.
