LOINC display name : Immunoglobulin light chains.kappa.free/Immunoglobulin light chains.lambda.free Nephelometry (S) [Mass ratio];

LOINC long common name : Kappa light chains.free/Lambda light chains.free [Mass Ratio] in Serum by Nephelometry;

LOINC short name : Kappa LC Free/Lambda Free Ser Neph;

LOINC description : An elevated kappa/lambda ratio supports the diagnosis of a monoclonal gammopathy and requires further investigation. Borderline elevated kappa/lambda ratios occur with renal impairment, and may require appropriate renal function tests. Elevated levels of both kappa and lambda with normal kappa/lambda ratio - may be due to (1) renal impairment (common); (2) Over-production of polyclonal FLC from inflammatory conditions (common); (3) Bi-clonal gammopathies of different free light chain types (rare).;
