In patients with recently diagnosed MGUS, serum electrophoresis should be repeated after 3 months to exclude early myeloma. If the results are stable, the test should be repeated in 6 months. Patients should be aware that the evolution of MGUS to multiple myeloma can be abrupt; therefore, they should be reexamined promptly if their clinical condition deteriorates.
