If information says there is an M spike in blood. What does that mean in terms of melanoma

Hi. I saw my regular oncologist today and brought up the suspicious monoclonal immunoglobulin in my gamma region. I asked if it might be from Dara which I just started last month. He said NO and left it at that. He reminded me that this never goes away, I know, and that I’m still at undetectable levels. If I was, why would this show? He also
Reminded me that my remission would be short due to my genetic add ons what a happy guy. Hope I can prove him wrong.

M-spike 5.1 (began) now 0.5
After 5 cycles of Revlimid
In cycle 6 currently

I am three years in remission and I just got blood work done but my Kappa light chains were elevated but my Lambda light chains were normal. Can anybody advise me on why this could happen. They are normally both in range but my Kappa is really elevated. I am trying to have faith but my protein electrophoresis is not back yet which shows whether there is any monoclonal proteins in my blood or not.. asking for advice and prayers. I have already had one stem cell transplant and chemo to put my MM… read more

Right now my parathyroid and calcium are too high. I'm waiting for an appointment with an endocrinologist.

Newly diagnosed MM. IGG lambda light chain and on my second cycle of RVd. Recent blood work done shows my IGG level dropped from about 6000 to 1144. Kappa light chain serum went from 500 to 23. Albumin 3.4 and protein total 5.9. I don’t see anywhere on the blood work where it shows M protein level. Would it be listed by another name? Not sure which lab levels are the most important? Thanks

M spike protein 0.32

Can someone explain if there’s a difference in “Light Chain MM” between “Kappa” and “Lambda” light chain MMs?
