Interpretative Information
IgD is one of the five classes of immunoglobulin. IgD is mainly found on the surface of B-cells and may help regulate B-cell function. IgD likely serves as an early B-cell antigen receptor, however, the function of the circulating IgD is largely unknown. Quantifying IgD aids in diagnosis or monitoring of IgD monoclonal gammopathies and IgD-related immune deficiencies.
