Human Beta-2 Microglobulin (B2M) is a small (11kD) polypeptide that forms the invariant subunit of the class I HLA-antigens (Human Lymphocyte Antigen) on the cell membrane (1). Increased concentrations of B2M in serum have been found in patients with renal diseases, malignancies (especially of lymphatic origin) and infectious diseases, e.g., AIDS. B2M is the most powerful single prognostic variable in multiple myelome, it is also a good predictor for acute rejection in renal transplantation, furthermore the measurement of B2M is very useful for detecting and monitoring the changes in the glomerular filtration rate in diabetic nephropathy.
