How do doctors test for allergies in teens who just developed symptoms this spring?

See below. You may not need any testing. Common spring allergies are tree pollen, flowers, and grass. If you are observant, you will be able to determine your triggers. If testing is needed, skin testing or blood work maybe performed.
Skin testing is best. Skin testing is the preferred method of allergy testing for all ages. Testing is helpful to pinpoint the specific allergen. It is quick, accurate and less expensive than blood tests. It is common to mistake the culprit allergen---in the fall people blame goldenrod when ragweed or mold is it. In the spring, trees are the usual culprit. While pine produces much pollen, it is hardwood trees!
