Skin Prick Testing

With skin prick testing, the skin of the upper back or forearms is touched with a little toothpick-like medical device coated with a specific allergen.

If your immune system recognizes a specific substance as a problem, it will form a little bump or hive in that area indicating that you possess allergic antibodies to that substance.

Intra-dermal Skin Testing

This method is typically reserved for adults and older children and is used when the skin prick test to environmental allergens is negative (nonreactive). It involves the application of allergens into a slightly deeper layer of skin.

Allergies and allergic reactions are your body’s immune system responding to something it thinks is attacking it.

When your immune system senses an allergen, such as pollen, it identifies the pollen as an “invader” and then your immune system mounts a response.

This response is your immune system overreacting and producing antibodies called Immunoglobulin E (or IgE). These antibodies then cause cells throughout your body to release other chemicals, causing the allergic reaction numerous are familiar with. The only way to know for certain if you are allergic to something is through formal allergy testing.

Allergy testing is typically accomplished by either an allergy blood test or skin test.
