Kappa light chains/Lambda light chains [Mass Ratio] in Serum by Immunoassay

Active

Part Description

LP15030-7 Immunoglobulin light chains.kappa
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.

Fully-Specified Name

Component: Immunoglobulin light chains.kappa/Immunoglobulin light chains.lambda
Property: MRto
Time: Pt
System: Ser
Scale: Qn
Method: IA

Additional Names

Short Name: Kappa LC/Lambda Ser IA
Display Name: Immunoglobulin light chains.kappa/Immunoglobulin light chains.lambda IA (S) [Mass ratio]
Consumer Name Alpha Get Info: Immunoglobulin light chains.kappa/Immunoglobulin Light Chains.lambda, Blood

Basic Attributes

Class: CHEM
Type: Laboratory
First Released: Version 1.0h(2)
Last Updated: Version 2.73
Change Reason: 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.kappa/Immunoglobulin light chains.lambda' to ' Kappa light chains/Lambda light chains' for readability.
