Useless test: K/L ratio is not a useful test. About one third of patients without monoclonal immunoglboulin have an abnormal ratio, usually with kappa excess. If you must, the next step would be a bone marrow examination. You may consult this article that I wrote: https://www.ncbi.nlm.nih.gov/pubmed/27473738 At your age you are unlikely to have myeloma.

We need more inform: We need more information. next up is a bone marrow but I really doubt this is legacy. It would certainly be very unusual your age
