Performing Lab
Kappa/Lambda Light Chains, Total, Serum
Also known as: Kappa/Lambda, Total, Kappa and Lambda, Quantitation
Clinical Use
Order TestUse
Measurement of total kappa and lambda immunoglobulin light chains in serum provides valuable information for the diagnosis and monitoring of plasma cell dyscrasias such as multiple myeloma, lymphoproliferative disorders, and related conditions. The ratio of kappa to lambda chains can indicate clonal expansion and help assess disease activity.
