Skin Prick Test

What is Skin Prick Test

The skin prick test is a common method of determining whether a person is sensitised to various allergens. It can also determine a person's degree of sensitivity to various allergens. The skin prick test is economical, and the results are immediate.

A small needle is used to gently prick the skin with a drop of fluid containing a known allergen. It is usually done on the forearm. The test is usually not painful.

A positive reaction to the skin prick test occurs when the skin around the needle prick becomes itchy and red, with the development of a white swelling called a wheal. The wheal reaches its maximum size in about 15 to 20 minutes, and the reaction fades within a few hours. The larger the wheal, the more likely it is that you are allergic.

We offer four allergen panels:

The allergens not listed in your selected panel but available in the other three panels can be added on at $43.60 per allergen. Please inform us if you would like to purchase any of the add-on allergens when making your appointment.
