This test is used to evaluate the level of immunoglobulin (IgG) in the blood. IgG is vital in immune system strength of the body and decrease in the level of IgG can lead to recurrent infections as immune system becomes weak and vulnerable. This test is also recommended for the evaluation of IgG levels in various myelomas as increased IgG are indicative of myelomas, cancer of antibody producing cells (plasma cells). The acquired immunodeficiency syndrome (AIDS) is also characterized by increased level of polyclonal IgG.
