A skin test involves using a small amount of a thought allergen to the skin and watching for a reaction. The substance might be taped to the skin (patch test), applied via a small prick to the skin (prick test), or injected just under the skin (intradermal test). A skin test is most important for detecting:
- food allergy.
- mold, pollen, and animal dander allergic reaction.
- penicillin allergic reaction.
- venom allergy (such as mosquito bites or bee stings).
