A doctor has provided 1 answer
Http://myeloma.org/pdfs/U-Freelite-Eng2011_g2web.pdf: Go to the website above for good summary of KAPPA and LAMBDA values, and significance;; Normal levels of serum free light chains are*: • Kappa: 3.3–19.4 mg/L* • Lambda: 5.71–26.3 mg/L* • Kappa/lambda ratio: 0.26–1.65** *Note: The units here are mg/L; different laboratories use different units. It is important to double-check the units used when comparing numbers in lab values. **Further Note: In patients with renal impairment, it is recommended to interpret the results of the Kappa/Lambda ratio with a modified reference range of 0.37–3.1.
