Allergy skin testing identifies the specific allergens triggering your problem, allowing better avoidance and reduction of your symptoms. Allergy skin testing is a relatively pain free process performed by applying allergens on the skin (of the forearm) with a gentle skin based applicator and then under the skin with a very small injection. If a welt appears at the testing site, there is sensitivity to that particular allergen. These simple allergy testing methods give your physician the information required to design an effective treatment plan tailored to your specific needs, using a combination of avoidance techniques, medications and possibly allergy shots.
