Clinical Info
This ELISA measures IgG antibodies specific for IgE. These autoantibodies have been implicated as a causative agent in autoimmune chronic urticaria. They have also shown significance in atopic dermatitis and hyper IgE syndrome. A result of normal indicates that the level of IgG anti-IgE antibodies is similar to that seen in a population of healthy individuals. A result of elevated indicates an increased level of IgG anti-IgE antibodies compared to healthy individuals.
