Also known as: BMG
β2-microglobulin is an 11 KDa protein found on the surface of all nucleated human cells as a component polypeptide chain of the HLA Class I antigen complex. It is excreted via the renal glomerulus, the majority being reabsorbed in the proximal tubules. It exists in the serum as a stable monomer with no significant diurnal variation and is used to monitor B cell malignancy. High cell turnover in myeloma results in raised serum concentrations, and renal dysfunction will result in serum retention, further compounding this rise. Measurement of β2-Microglobulin indirectly reflects tumour mass, growth rate and renal function.
