Hello! I am wondering if anyone might have insight on this. My mom was diagnosed with non-secretory myeloma in June. At that time, I joined a clinical study for immediate family members. I received my results back, and my Kappa Light Chain was elevated at 22.36. All other results were normal (no m spike and normal immunoglobulins - which was the same for my mom, though she had significant disease by that time as shown on a PET scan). I am therefore not eligible to be referred for follow up as the those items were normal. Does anyone know if Kappa Light Chain can be elevated for a benign reason? Thank you so much!
