Staging Multiple Myeloma

Once a myeloma diagnosis is made, further tests may be ordered to help assess prognosis.

Multiple myeloma is staged using the International Staging System.

Each stage is determined by the level of two tests on blood samples called beta-2 microglobilin and albumin.

  • Stage I: Beta-2 microglobilin is less than 3.5 mg/dL and albumin >=3.5 g/dL
  • Stage II: Not I or III
  • Stage III: Beta-2 microglobilin >=5.5 mg/dL
