Immunoglobulin M, or IgM, are antibodies that are part of the initial immune response; IgM is typically the first immunoglobulin to appear following antigen exposure. The IgM test is most frequently ordered when a plasma cell cancer is suspected or in the evaluation of immune function. IgM is included in the immunoglobulin panel or it may be requested individually.
