The only way to treat your allergy symptoms is to determine exactly what is causing them. This is done through a series of allergy tests.
What Is a Skin Prick Test?
A skin prick test is the most common form of allergy testing. This test involves placing a small drop of an allergen extract on your skin. A needle is then used to prick the skin underneath the drop; this allows for a small amount of solution to enter just below the surface of the skin. After 15 minutes, any swelling or redness is measured and, depending on the size, is considered a positive reaction.
What is an Intradermal Skin Test?
An intradermal skin test is completed next. An intradermal wheal, or bleb, is injected directly under the top layer of skin. After 15 minutes any reactions are measured and classified as either positive or negative.
How Does a Blood Test Work?
At Sound Health, blood tests are typically used in lieu of skin tests if a serious allergy makes skin testing unsafe.
