The Immunoglobulin G or IGG test is one of the standard blood tests done to measure the amount of Immunoglobulin G antibodies present in your bloodstream. It is a laboratory procedure that assists in determining the blood levels of immunoglobulins A, G, and M. These immunoglobulins are antibodies produced by the human immune system to combat infection.
High IgG levels can be both good and bad, depending on the context. In general, elevated IgG indicates a robust immune response, which is beneficial for fighting infections and providing immunity. However, persistently high IgG levels may also suggest certain autoimmune or inflammatory conditions.
Yes, low IgG levels can be serious. IgG is a crucial antibody for immune function and defense against infections. Low IgG levels may lead to an increased susceptibility to infections, particularly bacterial and viral ones. It can also indicate underlying immunodeficiency disorders.
IgG deficiency disease, also known as Selective IgG Deficiency, is a medical condition characterized by lower than normal levels of Immunoglobulin G (IgG) antibodies in the blood. This primary immunodeficiency disorder can lead to an increased risk of infections, especially respiratory and gastrointestinal infections.
