So what information did your physician give you about MGUS? Have you been able to speak with him or her since receiving your lab results?
You’ll find that we might be more helpful to you if you give us a little more context of your question. Do you mind doing that?

In your blood work you should see Immunoglobulins IgG, IgA and IgM each assigned a value to compare to a "normal range value. My most recent IgG for example was 1443 mg/dl normal range is 603 - 1613 mg/dl This may vary depending on the lab. Mine was LabCorp. What was your IgG value?

"Kappa" you referred to is part of Free Kappa + Lamba Lt Chains. I assume your Free Kappa Lt Chains is probably high. Mine is high 43.9 mg/L compared to normal range value 3.3 - 19.4 mg/L. What was your Free Lamba Lt Chains?

Also, were you provided an M-Protein Spike. For two and a half years mine has stayed 0.6 to 0.7. What was your M-protein spike?
