Kappa/Lambda Light Chains Free with Ratio, Serum

Also known as: Immunoglobulin Free Light Chains

Clinical Use

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))
