There are 5 types of antibodies that fight the infections that affect our bodies. Usually, when an infection affects our body, IGg is produced to fight it. But in some people, due to genetic reasons, IGe is produced. IGe is the type of antibody that is usually hypersensitive. For different types of food or things, unique IGe will be produced. Allergy tests will determine whether IGe is present for the particular thing in the patient's body. Watch Dr. K. V. Raman, Chest Physician and Diabetologist at New Medical Centre Pondy talk about diagnosis and treatment for allergies.
