How does skin prick testing work?

The test is most commonly performed on your forearm. The skin is cleaned of any moisturisers or perfumes before a small prick is made into the skin through a drop of allergen extract. This lets just a small amount of the allergen into your skin.

If you are allergic to the allergen, a small itchy lump will appear within 15 – 20 minutes. Skin prick testing can be a little uncomfortable as you may experience some itching. But this should subside within a few hours.

There are allergies that cannot be tested for with a skin prick test like aspirin, food additives and respiratory (nose, throat) irritants like smoke or perfumes.
