A test chamber for epicutaneous patch test units is provided. The test chamber is formed of a multilayer material including at least one absorbent layer and at least one barrier layer. The test chamber is adapted to contain a liquid or petrolatum-based allergen. The absorbent layer absorbs the liquid or petrolatum-based allergen, while the barrier layer prevents the allergen from migrating out of the test chamber.
