Part Description

LP15031-5   Immunoglobulin light chains.lambda
All immunoglobulins contain two polypeptide chains: a long (heavy) and a short (light) chain. The two chains interact via disulfide bonds. There are two types of light chains, named kappa and lambda. Serum free light chain (SFLC) testing, a kappa/lambda ratio and a protein electrophoresis test are done to help detect, diagnose and monitor plasma cell disorders (dyscrasias) including multiple myeloma and primary amyloidosis. Normal readings are seen when there is a kappa/lambda ratio of approximately 0.26 to 1.65 and free light chains are present in the blood at low levels. Increased kappa free light chains and an increased kappa/lambda ratio are present with plasma cell disorders that produce excess monoclonal kappa light chains. The tests can also be used to monitor response to treatment. An increase in serum free light chains along with an abnormal kappa/lambda ratio may indicate primary amyloidosis; biopsy of affected tissue is typically used for confirmation of diagnosis.

Change Reason
The PrThr property is used for LOINC terms whose results are reported using an ordered categorical scale, regardless of whether or not an internal threshold was used to make that determination. This change was approved by the Laboratory LOINC Committee in June 2016.; The EIA method, which was always intended to cover more than just enzyme-linked immunoassay and whose display name for the long common name has always been Immunoassay, was renamed IA in order to eliminate ambiguity about whether the method has a broader meaning than just enzyme-linked immunoassay. Likewise, EIA.rapid was renamed IA.rapid. These changes were approved by the Laboratory LOINC Committee in June 2016. Changed the LCN from 'Immunoglobulin light chains.lambda' to ' Lambda light chains' for readability.
