Free kappa/lambda ratio in serum of normal individuals is 0.26-1.65.
Measurement of free light chain concentration in serum is useful for diagnosis, prognosis, monitoring disease activity and following response to therapy of these disorders.
Excess production of free kappa or lambda chains can alter this ratio. Monoclonal free light chains are found in serum of patients with multiple myeloma, Waldenstrom's macroglobulinemia, mu-heavy chain disease, primary amyloidosis, light chain deposition disease, monoclonal gammopathy of undetermined significance, and lymphoproliferative disorders.
