Test carried out by placing a drop of a suspected allergenic extract on the skin of the forearm and gently pricking it into the upper layer of skin. Sensitivity to a substance is indicated if the spot swells slightly and becomes red within about \(\pu{15 min}\).
Note: A positive result is far from conclusive and, at best, gives a vague indication of allergenicity. The prick test is inappropriate as a test for food allergens.
