I was wondering if I can have a high free kappa light chain and not have anything? In my blood tests it said that my kappa light chain was 2.62. In PROTEIN ELECTROPHORESIS PATH REVIEW, SERUM it said no monoclonal protein identified. Does that mean my doctor will do a bone marrow test next? Almost 2yrs ago I had squamous cell carcinoma growing in/on my foot. I had it surgically removed and was monitored with blood tests and PET CT'S. My doctor moved from within that hospital company to a new one. I liked NY doctor and had to search for him becaise I wanted him to keep being my doctor. Well I found him, he asked me if I've had any changes, I said yes I am tired all the time, I have trouble wanting to eat sometimes(I only get hungry for food once a day, sometimes not at all but have to force myself to eat because I will get nauseous, a headache and sometimes dizzy). He said he was going to do every blood test, even to check for anemia. He ordered a PET CT for me to take anywhere to have since I live so far away from where he practices now. My Free Kappa light chain is high. Any thoughts? Or ideas as to why?
