In lymphocyte phenotyping of periferial blood, what is the normal percentage for kappa and lambda light chains?

0.26-1.65 K/L ratio: Free light chains will normally be present in the blood at low levels, with a kappa/lambda ratio of about 0.26 to 1.65. Increased kappa free light chains and a higher kappa/lambda ratio may mean a plasma cell disorder producing excess monoclonal kappa chains. Increased lambda free light chains and a lower kappa/lambda ratio may mean a plasma cell disorder producing excess monoclonal lambda chains.
