Question

Quizplus · Accepted Answer

Patch tests are commonly used to detect contact hypersensitivity, which is a type of delayed allergic reaction that occurs after repeated exposure to a substance or chemical. During the test, small amounts of potential allergens are placed on patches and applied to the skin for a certain period of time. The skin is then monitored for any signs of redness, swelling, or other allergic reactions. Patch testing can help identify the specific allergen causing a person's contact dermatitis, and can be helpful in avoiding future exposure to that substance.
