ROAT

A skin test used to confirm or rule out the presence of allergic contact dermatitis, used after an initial patch test of a suspected allergen was negative or only weakly positive. The agent suspected of causing the reaction is applied to the skin twice a day for several days, and the skin is examined for eczema. The presence of a rash after ROAT implies the patient is truly allergic to the applied agent.
