Information about serum FLC measurement in nonsecretory myeloma, monoclonal light chain diseases, and reference populations is reported in the literature (1-5,7), but there is limited data about FLCs in renal disease, monoclonal gammopathy of undetermined significance (MGUS), and myeloma patients after autologous stem cell transplants.
Practical considerations for the measurement of free light chains in serum
The Freelite assay is a sensitive automated immunoassay for [kappa] and [lambda] FLCs in serum (3) and has been useful for the diagnosis and monitoring of patients with nonsecretory myeloma (4).
Detection of monoclonal proteins in sera by capillary zone electrophoresis and free light chain measurements
The clinical application of serum free light chain measurements was particularly apparent for detecting and monitoring patients with nonsecretory myeloma and primary amyloidosis.
