Casandra Test Code QD62478Version 1 (DRAFT)
Kappa/Lambda Light Chains Free with Ratio, Serum
Also known as: Immunoglobulin Free Light Chains
Use
Measurement of free kappa and free lambda light chains in serum assists in diagnosis, prognosis, monitoring disease activity, and response to therapy for plasma cell disorders such as multiple myeloma, Waldenström’s macroglobulinemia, primary amyloidosis, light chain deposition disease, and monoclonal gammopathy of undetermined significance. Normal kappa/lambda ratio range is approximately 0.26–1.65. ([intellitestmanager.questdiagnostics.com](https://intellitestmanager.questdiagnostics.com/home/output/207784?utm_source=openai))
