responding to @teedee66. It is my understanding that MGUS is a benign condition that means there is a higher than normal level of a protein M in your blood. At least this is what my doctor has explained to me, and that sometimes it can lead to more serious problems such as being more at risk for certain types of blood cancers. I recently had some IgG lab tests completed, all of which were flagged. Sadly, my doctor could not explain all of them and has referred me to a hematologist for further workup because I also have Lambda Kappa Light Chain disorders that also showed up in recent labs. Once I see the hematologist, I hope, like you, to have a more clear understanding, My doctor has suggested to me that there is a concern that I may have multiple myeloma, which was startling. However, I am not giving it much thought until I know for certain that I do in fact, have this condition that killed my father.
I hope you find what you are looking for.

Hi @teedee66, I moved your post about IgA lambda MGUS to this existing discussion:

- MGUS and quite high Free Kappa Light Chain and Kappa Lambda Ratio: https://connect.mayoclinic.org/discussion/mgus-and-quite-high-free-kappa-light-chain-and-kappa-lambda-ratio/

I did this so you can read previous posts and connect more easily with members like @jart @pmm @gingerw @justnate @loribmt @packgb19 and many others.
