Skin Prick Testing

When having a skin prick allergy test, your skin is exposed to suspected allergy-causing substances (allergens) and is then observed for signs of an allergic reaction.

During your skin prick test, a grid is drawn on your skin generally on your underarm from your wrist to your elbow. Each grid represents an individual allergen. 

​

A 1000th strength dose of allergen is introduced to the system by way of a droplet. An instrument know as a Lancet is used to create a small scratch on the surface of the skin, this allows the allergen to penetrate.

​

The allergen then incubates for 10 mins.

 

A histamine control system is used to measure the reaction that appears as a hive on the skin. This is measured in cubic millimeters indicating the level of allergen reaction in the body.
