Hi,
I have high Kappa 2.62 and high kappa/lambda ratio 1.94. My last blood work was 2 weeks ago, and now says I have IgM lambda protein present in serum, but does not say any levels or numbers by it. I went to Mayo in 2022 for cardiomyopathy. They did tests for cardiomyopathy and blood work that caught the high FLC. My Mayo Cardiologist did not think I have MM or amylodosis. I hope they are right. This is scary stuff. So far in my home town they are watching it, and I have blood draws every 6 months.

I hope you continue to get answers you need. It helps to know there are others out there with same findings. Best regards.
