HI, I had SCT in May. I have IGG Kappa. My light chains are staying within range but Kappas are close to the top of the range and fluctuate a lot. The Kappa/lambda ratio is usually 0.80-.90 but lately Lambda is lower than Kappa and ratio is around 1.10. Is that normal? Is it ok for Kappa's to be close to top of the range? It makes me concerned when it reaches near the top of the range.
