Peanut IgE Component Panel (Sendout)
General Information
Lab Name
Peanut IgE Component Panel (Sendout)
Lab Code
RPICAP
Epic Name
Peanut IgE Component Panel (Sendout)
External Test Id
2007211
Description
Test Information: This panel includes Peanut IgE, Severe Peanut Ara h 1, Severe Peanut Ara h 1, Severe Peanut Ara h 3, Severe Peanut Ara h 9, Mild Peanut Ara h 8, and Severe Peanut Ara h 6. Allergen results of 0.10-0.34 kU/L for whole peanut 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 vivo reactivity to specific allergens is essential. A negative test may not rule out clinical allergy or even anaphylaxis.
