I am new to this and trying to learn. My M-spike is at 1.70 g/dL, my lambda light chain is 87.02 mg/L, Light chain ratio is .21, and my IgG level is at 1962 mg/dL. Has anyone found an easy way to explain this somewhere? Last visit in May my doctor would only say he was concerned. My blood draw this week did not improve and I met with him next week. I am, of course, worried.
