Question

Quizplus · Accepted Answer

Patch tests are used to detect contact hypersensitivity, which is an immune response to an external substance that has come into contact with the skin. Patch tests can help identify the specific substance that triggers the allergic reaction so that it can be avoided in the future. Hives, serum sickness, immune complexes, and Arthus reaction are all types of immune-mediated reactions, but they are not specifically tested for with patch tests.
