Our skin testing procedure checks for insect, food, and airborne allergens through the measurement of your allergic antibodies levels to these allergens. To do this we use a small plastic device that applies tiny amounts of solutions to the skin with a prick or scratch that contain the various types of allergens. By checking for an area of raised skin, we’ll be able to determine if there is a positive reaction. However, even if there is an area of raised skin, it does not necessarily mean you are allergic to an allergen, as other factors play a role in the test. If an allergen does not show up on a prick test, we will repeat the test using a tiny needle in which we will inject a small amount of that allergen into the first layer of skin, which will form a small, mosquito-like bite bubble. This test typically yields results in 15-20 minutes, and the area tested could get itchy, but not for very long. Prior to having this test administered, you should avoid using antihistamines 5 to 7 days before coming in to get tested. This skin test is not usually performed on those who have suffered a life-threatening reaction, or to someone who has hives or severe eczema.
