An immunoglobulin test measures the amount of immunoglobulins, also known as antibodies, in the blood. It measures three specific types of immunoglobulins- IgG, IgM, and IgA.

An immunoglobulin in the blood help diagnose a variety of medical conditions, including bacterial or viral infections, immunodeficiency, autoimmune disorders, certain cancers, and infections in neonates.
