Immunoglobulin G Blood Test

An Immunoglobulin G Blood Test is a quantitation of IgG.

Description

Immunoglobulin G (IgG) is part of the immune system response found in the blood. If an infection, toxin or foreign body of any kind is detected in the bloodstream, the body reacts by pushing IgM (Immunoglobulin M) to the area affected. IgM is the largest antibody. It works to start the healing and recovery process. In the meantime, when IgM responds IgG production quickens. Together with other immunoglobulins, IgG works to basically get rid of the problem.
