Beta-2 microglobulin is a protein produced by myeloma cells. Higher levels of this protein in your blood typically indicate:

• More advanced stages of multiple myeloma
• More aggressive disease progression
• Later disease stages

For context, in the Revised International Staging System (R-ISS), levels above 5.5 milligrams per liter are considered high and may indicate stage 3 myeloma when combined with other factors. Your healthcare team will look at beta-2 microglobulin levels along with other important markers to determine your specific stage and treatment plan, including:

• Albumin levels
• LDH (lactate dehydrogenase) levels
• Genetic abnormalities in cancer cells

It's important to discuss your specific test results with your doctor to understand how they impact your treatment options and outlook.
