What tests are generally used to diagnose allergies?
First, keep in mind that allergy tests are not the sole basis for diagnosing or treating an allergy. Health care providers make an allergy diagnosis based on several factors: • History of the child’s experiences and family history of allergy/asthma • Physical exam of the child to detect signs of allergy • Allergy testing for sensitivity to specific allergens Allergy tests help your physician confirm allergies your child may have. When an allergy test pinpoints a reaction to a specific allergen(s), your health care provider also can use this information in developing “immunotherapy” — allergy shots — specifically for your child, if appropriate. Skin Tests for Allergies Skin prick tests are the most common tests for allergy. Small amounts of suspect allergy triggers are introduced through the skin of the arm or back by pricking or puncturing the skin with a needle or similar device. If your child is allergic to a substance, you will see a raised, red itchy bump, also called a “wheal.” Re
