About this study

The initial diagnostic work up of suspected food allergy includes patient's history, skin prick test (SPT), measurement of food specific immunoglobulin E (IgE) with serological assays, and more recently the atopy patch test. A positive SPT seems to reflect early reactions to food challenges, whereas the atopy patch test has a high diagnostic efficacy for late phase clinical reactions. The purpose of this study was to evaluate atopy patch test reaction in non-atopic population.

Treatment and study plan

Atopy patch test with food allergen

Device

Atopy patches used with food lyophilized allergen and commercial allergen were placed on back of subjects for 48 hrs then atopy patches were taken off. Subjects should return to evaluate reaction one day later(72 hrs after applying atopy patch test)
