During a Skin Prick Test, your skin is exposed to suspected allergy-causing substances (allergens) and is then observed for signs of an allergic reaction. Along with your medical history, allergy tests may be able to confirm whether a particular substance you touch, breath or eat is causing symptoms.
What is an Allergy Skin Prick Test?
Skin prick testing is an allergy test used to identify allergens responsible for triggering symptoms in allergic diseases. Skin prick testing is useful in the diagnosis of other allergies such as those that cause hay fever, food allergy or bee and wasp allergy. The gold standard for allergy testing is as simple as pricking your skin, inserting a small amount of a substance (allergen) and waiting to see what happens. If you are allergic to the substance, a reddish elevated bump with a red ring around it will appear. The bump may be very itchy.
What is an Allergen?
An allergen is any substance that elicits an allergic reaction. Skin prick testing is most often used to demonstrate atopy. Atopy is characterised by an overactive immune response to environmental factors. It usually manifests clinically as one or more of the characteristics disorders of asthma, eczema or hay fever (rhinitis). The results from skin prick testing can be used to guide the management of patients with asthma and hay fever, for example, desensitization of a certain allergen, removal of a family pet, removal of rugs or dust causing items and avoidance of certain foods.
