IgD multiple myeloma is characterized by a small or absent M-protein band in electrophoresis, a Lambda (A) light chain bias, and Bence-Jones proteinuria, which occurred in at least 90% of patients (7).
Furthermore, Lolin et al (1994) suggested that immunofix with IgD and IgE antisera should routinely be performed for all patients with a suspected Bence-Jones proteinuria myeloma, irrespective of whether a suspicious band was detected on serum protein electrophoresis or after immunofixation with light chains (9).
