WebThis can be helpful in diagnosing multiple myeloma if an M-protein isn’t found by SPEP. A serum free light chain test also measures the light chain ratio. The light chain ratio shows if the amount of each light chain is out of balance, which can be a sign of multiple myeloma. Immunoglobulins have 2 types of light chains – kappa and lambda. WebThe serum free light chain (SFLC) assay picks up tiny amounts of small proteins called free light chains in the blood. This is a smaller part of the myeloma protein called light chain that is also made by myeloma cells. It is particularly useful for diagnosing and monitoring light chain myeloma (where light chain is the only abnormal protein ...
