Atopic Dictionary
PRICK tests or skin prick tests are tests used to detect sensitizations or allergies to a certain allergen. It's about proving hypersensitivity mediated by IgE. The test is performed by first drawing a grid on the forearm, onto which drops of individual allergens are applied, then the skin is minimally damaged over a drop of allergen with a tiny plastic stick (there is no bleeding). After this, wait approximately 20 minutes, then the test is read. If a wheal appears on the test field and the area itches, the test has proven sensitization to a certain allergen.
