It is normal to have some protein in your blood. The normal range is 60 – 80 g/l. Anything above this may suggest a monoclonal protein, not normal, could be myeloma. At diagnosis my serum protein level was 96. There are two less serious subtypes of myeloma that may not develop into active myeloma (requiring treatment), MGUS and Smoldering Myeloma. Its good that you are seeing a haematologist, who will also investigate your shoulder pain, but it may be that you haven’t got full blown MM.
