a test to discover which allergen is responsible for contact dermatitis in a patient. Very low concentrations of common allergens (and any substances suspected of causing the dermatitis in the individual patient) are applied under a patch on the back. The patches are removed after 48 hours and the underlying skin is examined then and again after a further 48 hours. A positive test will show an eczematous reaction. The commonest allergens are nickel in women and chromium in men.
