With the addition of the serum free light-chain (FLC) assay, the expanded monoclonal protein study provides even more diagnostic sensitivity for the monoclonal light-chain diseases such as primary amyloid and light-chain deposition disease; disorders that often do not have serum monoclonal proteins in high enough concentration to be detected and quantitated by PEL. Another test, called immunofixation or immunoelectrophoresis, is used to determine the exact type of abnormal antibody (IgG. High blood protein. Weill Cornell Medicine Myeloma Center It is recommended that serum and urine protein electrophoresis (PEL) and immunofixation electrophoresis (IFE) be performed as part of the diagnostic algorithm (eg, MPSS / Monoclonal Protein Study, Serum and MPSU / Monoclonal Protein Study, 24 Hour, Urine). If a monoclonal light chain is detected in the absence of an associated monoclonal heavy chain, an immunofixation electrophoresis specific for delta and epsilon chains is performed. For example, if a Monoclonal Antibody binds to protein X with a Z-score of 43 and to protein Y with a Z-score of 14, then the S-score for the binding of that Monoclonal Antibody to protein X is equal to 29.
