MGUS and quite high Free Kappa Light Chain and Kappa Lambda Ratio

Posted by jart @jart, May 15, 2022

The above was found in his blood serum test but follow-up 24 hr urine test showed only 2 free Kappas. Has anyone had experience with this? Does the urine test supersede the serum testing? Either way, is there anything to do other than “watchful waiting?”

BTW, he also has Dysautonomia (Diabetic T2).

Interested in more discussions like this? Go to the Blood Cancers & Disorders Support Group.

@jart, I would like to bring @gingerw @justnate @loribmt and @packgb19 into this discussion to help answer your questions or even to help you to formulate questions to ask the cancer care team.

I can see that you are concerned about the treatment protocol being "only" watchful waiting. I prefer to refer to this as active surveillance. Watching waiting doesn't mean do nothing. Instead it refers to not administering treatment that could potentially do more harm than good in the early stages of a condition that may progress very slowly.

Did you discuss the blood and urine tests with the doctor yet?
