Skin prick tests (SPTs) and total serum IgE level determination are useful in diagnosing allergy in even very young children but testing for inhalant allergens is not necessary in children younger than one year of age, say Polish researchers.

The researchers, from the Medical University of Bialystok, tested 348 children aged from five to 36 months for food allergies and reaction to inhalant allergens. All of the participants received skin-prick tests for 12 food allergens. Two hundred and twenty nine of the children were tested for nine inhalant allergens. The investigators also determined total IgE levels in 291.

They report that overall they obtained positive SPT results in 15.8 percent of participants. Positive inhalant results were found in 21.8 percent but results differed according to the children's ages: "During the first year of life, a predominance of food allergy was observed."
