From: Prevalence of childhood eczema and food sensitization in the First Nations reserve of Natuashish, Labrador, Canada

  1. *Normal IgE: Age 2–9 years = 0–52 kIU/L, Age >9 years = 0–199 kIU/L.
  2. §All but one of these 13 children were in the 2–9 year age group, thus 12/13 had IgE levels above the age appropriate reference range.
