IMMUNOGLOBULIN G (IGG)

The immunoglobulin G (IgG) test measures the level of IgG antibodies in the blood. IgG antibodies are the most abundant type of antibody and play a crucial role in long-term immunity. This test is used to diagnose and monitor immunodeficiency disorders, such as common variable immunodeficiency (CVID), and autoimmune diseases. Elevated IgG levels can indicate chronic infections or autoimmune disorders, while low levels suggest immunodeficiency. The IgG test provides valuable information for assessing immune function, diagnosing underlying conditions, and guiding treatment decisions. It helps ensure optimal immune health and prevent complications associated with immunodeficiency.
