I was just diagnosed with MGUS after routine blood work and then some more. I have been googling and reading everything I can. My Kappa/lamda ratio is 38.91,my IGA is low and my IGG is high, IGM is normal. All my protein levels seemed to have jumped up in the last month which may indicate infection and inflammation. I didn't get to see a hematologist but the nurse really wants me to get a bone biopsy. I feel like this could give a false baseline-having read several entries here I am not sure what to do. Thanks for any insights.
