High free light chains normal ratio
Web18 de out. de 2004 · In addition to measuring the levels of FLC, the test also enabled the clonality to be assessed, based on the ratio of kappa/lambda light chain levels. The normal range for free-kappa light chain is 3·3–19·4 mg/l, whereas the normal range for free-lambda light chain is 5·7–26·3 mg/l in this assay. Web1 de ago. de 2005 · The normal reference range of 0.26 to 1.65 for the free-kappa–lambda ratio in the FLC assay reflects a higher serum level of free-lambda light chains than would be expected given the usual kappa-lambda ratio of 2 for intact immunoglobulins.

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) .
