lol I think we have the same sister. And one was Labcorp(consistently over 1.2 for 2-3 years) and the other at MSKCC (taken twice in a two week period and 3 mths back. All around .8). But my kappa(115 or 11.5) and K/L (9.99)ratio is still up.
I went to MSK because my original hemonc said I was now in the smoldering and at the time with a mspike of 1.4 and 8% BMB I knew I wasn’t there just yet, so I went to the experts.
