There is often a history of other allergies and sensitive skin, and some people may also have asthma.
A skin prick test may be able to identify the offending allergen (substance that triggers the allergic response). It is a simple test performed in the clinic.
In a skin prick test, a small area of skin, usually on the forearm is used to test for allergies to various allergens. A small amount of allergen is then applied to the skin and the area observed for a positive reaction.
By identifying the allergen, severe or recurrent attacks can be reduced by avoiding or minimising subsequent exposure to the allergen. Common allergens include dust mites and pollen.
