Interpretive Data
Allergen, Food, Peanut IgE for additional Interpretive Data:
Allergen results of 0.10-0.34 kU/L are intended for specialist use as the clinical relevance is undetermined. Even though increasing ranges are reflective of increasing concentrations of allergen-specific IgE, these concentrations may not correlate with the degree of clinical response or skin testing results when challenged with a specific allergen. The correlation of allergy laboratory results with clinical history and in vivoreactivity to specific allergens is essential. A negative test may not rule out clinical allergy or even anaphylaxis.

Allergen, Food, Peanut Component Interp:
Negative:
No specific antibodies to peanut detected. However, this does not rule out in vivo sensitivity.
Mild Risk:
May be associated with mild or localized reactions. Suggest consultation with specialist.
Severe Risk:
Ara h 1, 2, 3, and 9 are the peanut proteins most linked to systemic allergic reactions. If any one of these 4 components is positive, the patient has a high risk of systemic allergic reaction when exposed to peanuts.
Inconclusive:
Will be reported if one of the following patterns is found:
1. Antibodies to Peanut IgE (whole peanut) detected but all peanut components were negative. Repeat testing with a new specimen or refer to a specialist.
2. One or more peanut components were positive but Peanut IgE (whole peanut) was negative. Repeat testing with a new specimen or refer to a specialist.  
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.
