Intravenous Immunoglobulin (IVIg, IgG)

Intravenous immunoglobulin is frequently abbreviated as IVIg or IgG (for intravenous gamma globulin). This procedure is used in the treatment of immune system disorders. It also is performed to improve the immune system's reaction to a serious illness. Concentrated antibodies collected from healthy individuals are put in a sterile solution and injected directly into a vein to help fight illness.
