Good evening! In May of this year I was diagnosed with MGUS (with a low Mspike .37) and bone marrow biopsy results being small population of lambda-restricted plasma cells. My hematologist/oncologist said we would repeat blood work again in November. I just had blood work completed because I had to change hematologist/oncologist due to insurance. My results: no monoclonal protein; Beta 2 Globulin % High; Kappa Free Light Chain High; WBC low; RBC low; MCV high; Neutrophils low; Monocytes high; Neutrophil absolute low. All other labs were normal. Can anyone give me insight? Has anyone ever had a positive Mspike and then it be negative even withouth treatment? Any insight would be helpful! Thanks in advance.
