High serum free light chains
WebNormally, light chains are produced in humans at about 500 mg/day. Although approximately twice as much κ as λ is produced, renal clearance of the larger, dimeric λ light chains is slower, causing the normal κ:λ ratio to be about 0.58 (range 0.26–1.65 mg/L, median serum κ level of 7.3 mg/L, median serum λ of 12.7 mg/L) . With infection ... WebAug 1, 2005 · A novel, highly sensitive serum free light chain (FLC) assay is now available for clinical practice. 12 It allows quantitation of free kappa (κ) and lambda (λ) chains (ie, light chains that are not bound to intact immunoglobulin) secreted by plasma cells.
