Allergy Testing

Allergy Testing


Having allergies is your body’s immune system reaction to a substance you inhaled, touched or ate. Your immune system overreacts by producing antibodies and these antibodies travel to cells that release chemicals, causing an allergic reaction. These reactions can range from annoying sneezing and sniffling to a life-threatening response called anaphylaxis.
More than 50 million people in the United States have allergies. Finding out what you are allergic to is an important first step to effective allergy treatment. Today allergy tests are more convenient and accurate than ever before. When combined with a detailed medical history, allergy testing can identify the specific things that trigger your allergic reactions.

There are two types of skin tests. During the first type of skin test, a drop of a suspected allergen is scratched on the surface of the skin. The test is performed on the back or forearm. Many suspected allergens are tested at the same time. If you are allergic to one of the tests, you will have redness and swelling at the test spot.

Skin testing is fast. For both types of skin tests, positive reactions usually appear within 20 minutes. Sometimes redness and swelling can occur several hours after skin testing. The delayed reaction usually disappears in 24 to 48 hours, but should be reported to the allergy doctor or nurse.
