Our bodies can develop allergic reactions to several things. The total IgE test is used to help screen and detect these allergens in the body. The test measures the level of IgE (immunoglobulin E) in the body, which is an antibody created by the body’s immune system to fight any threat that the body perceives. IgE is associated with several problems that are allergic reactions. Your doctor may ask you for an IgE test if you are battling problems that are connected to allergic reactions, especially if you and your doctor are unaware of the allergen that is causing the problem. Some symptoms may be persistent itching, itchy eyes, nausea, vomiting, and symptoms of asthma.
