Immunoglobulin G (IgG) is the most common class of antibody in the blood and other bodily fluids. These antibodies are crucial components of the immune system because they help protect the body against bacterial and viral infections.
A test for Immunoglobulin IgG can be useful for determining how your immune system responds to infections or for checking for immunity problems. It can also assist in diagnosing certain immune disorders, such as a chronic infection or an autoimmune disease.
The amount of IgG in your blood provides information about your immune system and how it responds to infections. A normal level suggests that your immune system is functioning correctly, while abnormal levels indicate potential health problems.
A high level of IgG may indicate a recent or chronic infection. It might also point to an autoimmune disease, where the body mistakenly attacks its own cells.
A low level of IgG may indicate that you have a weakened immune system, making you more susceptible to infections. It can also be a sign of a specific immunodeficiency, where the body does not produce sufficient antibodies.
