"Prick skin test" - Hospitals Glossary Terms and Abbreviations
A test to determine if a child is allergic to certain substances. A physician places a drop of the substance being tested on the child's forearm or back and pricks the skin with a needle, allowing a tiny amount to enter the skin. If the child is allergic to the substance, a wheal (mosquito bite-like bump) will form at the site within about 15 minutes.
