The occlusive patch test is a skin patch test used to identify contact allergies. The test consists of applying a small amount of the suspected allergen to the skin and covering it with a closed patch. The patch is left on for a specified period of time (usually 48 hours) and then removed. Any resulting skin reaction is then examined and evaluated.
