13599 IUPAC Gold Book - prick test 10.1351/goldbook.13599 13599 current 1 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 \(\pu{15 min}\). 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. allergenic https://goldbook.iupac.org/terms/view/12857 PAC, 2012, 84, 1113.
