Skin tests are done in an allergist’s office.

There are two types of skin tests:

  • Prick or scratch test: In this test, a tiny drop of a possible allergen—something you may be allergic to—is pricked or scratched into the skin. (This is also called a percutaneous test.) It is the most common type of skin test.
  • Intradermal test: This test shows whether someone is allergic to things such as insect stings and penicillin. A small amount of the possible allergen is injected under the skin through a thin needle.
