Serum FLC concentrations in patients with dialysis-dependent, acute renal failure. The FLC ratio easily distinguishes dialysis patients with κ (triangles) and λ (squares) multiple myeloma from patients with no evidence of monoclonal gammopathies (diamonds). Published normal control patients (crosses)12 have significantly lower concentrations of polyclonal FLCs compared with the dialysis population (both P < 0.001).
