Glossary Allergy Testing

medical procedure identifying allergic reactions to specific substances

Allergy testing, also known as allergen testing, is a medical procedure used to determine if a person has an allergic reaction to specific substances. This can be done through skin tests, where small amounts of potential allergens are introduced to the skin, or blood tests, which measure the presence of specific antibodies. These tests help identify triggers for allergic reactions, aiding in the diagnosis and management of allergies.
