WebNormal test results for free light chains are: 3.3 to 19.4 mg/L kappa free light chains. 5.7 to 26.3 mg/L lambda free light chains. 0.26 to 1.65 ratio of kappa/lambda. If your results are … WebThe more free light chains in your blood, the more plasma cells you have. This may mean there is a problem with the plasma cells. This test is used to help diagnose a type of cancer called multiple myeloma. It may also be used to diagnose other conditions affecting the cells in your bone marrow.
WebVery high levels of light chains can cause antigen excess, which in turn can result in falsely low SFLC results with nephelometric techniques. For large multi-center clinical trials, using a centralized lab is an option to avoid lot-to-lot variation issues. WebWhile the molecular weight of both light chains is approximately 22.5 kilodaltons, in serum, κ free light chain (κ-FLC) exists primarily as a monomer and λ free light chain (λ-FLC) as a covalently-linked dimer with a molecular weight of approximately 45 kilodaltons. This will lead to a differential glomerular filtration rate for κ-FLC and ...
