This ELISA measures IgG antibodies specific for IgE. These autoantibodies have been implicated as a causative agent in autoimmune chronic urticaria. In addition, these autoantibodies have also been implicated as significant in atopic dermatitis and hyper IgE syndrome.
IgG antibodies specific for IgE are detected with a solid phase indirect non-competitive ELISA. Human IgE is coated onto polystyrene micro-wells (solid-phase antigen). IgG antibodies in serum that bind to the IgE are detected with a labeled anti-human IgG antibody. This test has not been cleared or approved for diagnostic use by the U.S. Food and Drug Administration.
Qualitative test resulted as Normal or Elevated. 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.
Setup on Wednesday and reports on Thursday. TAT: 5-7 business days from receipt of specimen.
