patch test
Skin sensitivity screen
A patch test is a method of checking for allergic reactions by applying a small amount of a substance to the skin, typically covered with an adhesive patch, and observing the response over time.
Dermatologists use patch tests to identify contact allergies.
Hairdressers recommend them before applying hair dye: The instructions say to do a patch test 48 hours before coloring.
