During your visit, skin tests may be applied to help determine your suspected allergies. The test results will provide you with the knowledge you need to help make an informed decision regarding your health and treatment options. Skin testing is a quick (15-20 minutes), safe, and reliable way to assess for allergies. It is nearly painless and very well tolerated, even by small children (the sensation is similar to poking the skin with a pencil). The worst part of the test isn't pain, but itching, which occurs at the site of the allergens you are sensitive to. The itching usually resolves on it's own in about 20-60 minutes. Skin testing is very safe, even in people who are very allergic to things (foods, insects). Rest assured that you will be closed monitored during your visit to ensure that everything goes well.
In order to be able to perform a skin test accurately, you must stop certain medications several days prior to your appointment.
