LOINC display name : Immunoglobulin light chains.lambda.free Nephelometry (S) [Mass/Vol];
LOINC long common name : Lambda light chains.free [Mass/volume] in Serum by Nephelometry;
LOINC short name : Lambda LC Free Ser Neph-mCnc;
LOINC description : This nephelometric assay provides a sensitive test for monitoring patients with monoclonal
light chain diseases but no M-spike on protein electrophoresis, and may be more sensitive
than immunofixation for detection of monoclonal free light chains. In some patients
with non-secretory myeloma, systemic amyloidosis, or light chain deposition disease,
the nephelometric free light chain assay provides a positive identification of a monoclonal
serum light chain when the serum immunofixation is negative.;
