Allergic contact dermatitis occurs frequently in children. Patch testing is needed to identify the responsible allergens and should be performed in children. We recommend a panel of 12 contact allergens as a standard series in children from 6–12 years. Four additional contact allergens should be tested in case of a positive history or suggestive clinical picture. For patch testing in children, the allergens should be applied for 24 hours and the readings should be performed at 48 and 72 hours. Standardized patch testing makes it possible to systematically investigate allergic contact dermatitis and identify relevant allergens in children.
