Immunoglobulins are proteins found in human blood. This protein is called an "antibody" and is an important part of the body's defense against disease. When the body is attacked by harmful bacteria or viruses, antibodies help fight these invaders. Immunoglobin can be referred to by a number of abbreviations, including IgG, IGG, IGIV and IVIG.
Immunoglobulin therapy is ordered by a physician when the patient's body does not produce enough of its own or a temporary boost in immunoglobulin is helpful in treating a specific disease. The therapy helps the body fight off infection and helps control the symptoms of many chronic diseases. Immunoglobulin therapy can be used to treat a wide variety of health conditions, but it is not a cure. The IgG can be given through an IV each month, or under the skin, (subcutaneous) once a week. Both methods are effective at replacing IgG to levels necessary to fight infections
