  • 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 (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.
