Expand All Collapse All
Clinical Utility

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.

Procedure

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.
