prick test
Skin allergy check
A prick test is a diagnostic procedure where small amounts of allergens are introduced into the skin through tiny punctures, typically on the forearm or back.
The skin's reaction—redness, swelling—indicates sensitivity to specific substances: The prick test showed she was allergic to dust mites and cat dander.
Also called a skin prick test or scratch test.
