Notes

  • This is a screening test for paraproteinaemia. It is carried out in conjunction with serum immunoglobulins.
  • Both new and known paraproteins are quantified and any new paraproteins are typed to determine the heavy and light chain class.
  • Can be used to screen for Myeloma and MGUS, known patients require paraprotein monitoring.
