Kappa Light chains Light chains Lambda Serum free kappa light chains Normal range: 0.33-1.94 mg/dL Multiple myeloma or another plasma cell disorder may be indicated by increased kappa free light chains and an increased kappa/lambda ratio. Serum free lambda light chains Normal range: 0.57-2.63 mg/dL Multiple myeloma or another plasma cell disorder may be indicated by increased lambda free light chains and a decreased kappa/ lambda ratio. Serum free kappa/lambda ratio Normal range: 0.26-1.65 Abnormal kappa/lambda ratio may indicate excess production of the kappa or lambda light chain due to multiple myeloma.
