What is the Immunoglobulin Free Light Chain Assay and How is It Used?
The immunoglobulin free light chain assay (FREELITE, Binding Site, Birmingham, UK) is a very important assay that has been in use for nearly a decade. Its importance has been growing over time, and new uses for it have also been emerging.
Understanding Serum Free Light Chain Assays
In individuals with myeloma and related disorders such as monoclonal gammopathy of undetermined significance (MGUS), excess light chains enter the bloodstream. as free light chains. The amount of free light chain production is linked to the activity of myeloma or plasma cell growth.

FreeLite Test Measures Free Lambda And Kappa Light Chains In The Blood
This new test from The Binding Site measures free Lambda and Kappa light chains in the blood. The test is particularly useful for patients with non-secretory myeloma and is also being considered as a potential replacement for the 24 hour urine test
