What is immunoglobulin?

  • AStacy Wiegman, PharmD, Pharmacy, answered
    An immunoglobulin is a molecule that is present in the cells of the immune system and in serum. These immunoglobulin molecules work as antibodies and are produced by B-cells to fight bacteria or viruses. The antibody attaches to a bacteria or virus and destroys it. The B-cells are small white blood cells that are critical to a strong immune system. Any time your body has been attacked by a disease causing organism, your immune system will fight to get return to a healthy condition.

    Immunoglobulin (also called immune globulin or gamma globulin) is a protein in human blood and tissue fluids. These proteins are also called antibodies, which help the body's immune system recognize and destroy foreign substances, such as bacteria and viruses.

    Immunoglobulin (IG) may be given to help prevent an illness after exposure to an infected person. It can also be given to people with certain immune system deficiencies to prevent infections. Immunoglobulin is usually taken from the blood of people recovering from the illness. For example, the immunoglobulin given to help prevent hepatitis A infection is taken from the blood of people who are recovering from hepatitis A virus infection.

    The protection provided by an immunoglobulin injection lasts from days to months, depending on the disease.

    Immunoglobulin (Antibody) levels are proteins the immune system produces to fight infection. They come in four classes: Immunoglobulin (Ig) G, A, M, and E. An immunoglobulin test usually involves taking a small amount of blood and comparing antibody levels to standard levels for age.
