IgG (Immunoglobulin G) is a type of antibody found in the blood that plays a major role in the body's immune system. Antibodies are proteins that are produced by the body in response to a foreign substance, such as bacteria or a virus. IgG antibodies are the most abundant type of antibody in the body, and they are involved in the protection against many types of infection.
Is IgG a Warm or Cold Antibody?
IgG antibodies are considered to be ‘warm’ antibodies, meaning that they are produced in response to an infection that has already occurred. These antibodies are produced in large quantities and are found in the blood and other body fluids. They remain in the body for weeks or months after the initial infection has been cleared, providing long-term protection against reinfection.
In contrast, cold antibodies are produced in response to a foreign substance that has not yet been encountered by the body. These antibodies are produced in small quantities and are found mainly in the mucous membranes of the nose, mouth, and lungs. Since they are not found in the blood, they provide short-term protection against infection.
IgG antibodies are therefore considered to be ‘warm’ antibodies, as they are produced in response to a foreign substance that has already been encountered by the body. These antibodies play an important role in the body’s immune system, providing long-term protection against infection.
