Can someone give me advice as to where I stand. Approx 24 months ago I was referred to the haemo clinic due to igm paraprotein (serum). I understand it was 3.7 g/dl. I was given both bone and bone marrow biopsies which 'apparrently' were ok. I had further blood tests 6 months later and a further 6 months after that. At this stage my igm was 2.8 g/dl.I was then discharged and told I has mgus and didn't have to go back to the haemo clinic. I couldn't understand why after having marrow biopsies I was discharged. My doctor agreed to give me further blood tests and 6 months later my igm was 5.5 g/dl. My doctor queried this with the haemo specialist and they said they did not need to see me etc and that this reading of 5.5 was'really' the same as the prvious 2.8 value, but that 'it was now measured differently'. I would have assumed that g/dl is g/dl ???? whatever . As my reading of 5.5 is over the 3g/dl mgus benchmark have I got wm??? Confused, advice needed.
