Clinical Significance
Antibodies or immunoglobulins (Ig) are formed by plasma cells as a humoral immune response to antigens. The first antibodies formed after antigen stimulation are of the IgM class, followed later by IgG and also IgA antibodies. IgD normally occurs in serum in trace amounts. Changes in IgD concentration are used as a marker of changes in the size of the clone of monoclonal IgD plasma cells.
