Hi and thanks for the question.
Beta 2 microglobuilin is a small protein associated with multiple myeloma. In course of this disease, some chains of particular antibodies, including Beta 2 micrglobulin are produced.
The quantity or concentration of this substance in blood gives an indication of the stage of the disease, and measures the outcome or prognosis. The lower the concentrations of this substance, the better the outcome.

It is there fore measured to know the stage of the disease and to monitor the evolution of the patient under treatment. Increasing values imply that the treatment is not very effective, where as decreasing values implies the effectiveness, and good prognosis of the patient.

It is actually a measure of the morbidity and the mortality of the disease.
Thanks and hope this helps,
Luchuo, MD.
