Allergies - symptoms and how to test
Antibodies are chemicals manufactured by your immune system. You have an allergy when your immune system overreacts to something that wouldn't bother you, such as pollen, pet dander, or a meal that usually wouldn't bother you. You are more likely to get allergies if you have a close relative with asthma or allergies (such as hay fever, hives, or eczema), are allergic to things or have asthma. Your doctor may recommend that you avoid exposure to allergens, take medicine, or get allergy injections based on your allergy testing results. As a means of aiding in the diagnosis of a variety of allergy diseases, skin tests are frequently employed.
