[Sensitization to inhalant and food allergens in Brazilian atopic children by in vitro total and specific IgE assay. Allergy Project--PROAL].

Objective: To determine the frequency of sensitization to inhalant and food allergens in children seen at Brazilian allergy services.

Patients And Methods: Total and specific IgE serum levels to inhalant and food allergens (RAST, UniCAP - Pharmacia) were measured in 457 children accompanied in pediatric allergy services and in 62 control children age matched. RAST equal or higher than class 1 was considered as positive (R+).
