Reliable and high analytical performance results
with correct estimation of FLC values without antigen excess or overestimation by polymerization vs Nephelometry / Turbidimetry Methods.
Free Light Chains (FLC)
The next generation Free Light Chain Assay.
About FLC
- Free Light Chains (FLCs) are immunoglobulin light chains which are circulating in serum in a free state (unbound). There are two types of immunoglobulin light chain produced in humans, designated kappa (κ) and lambda (λ).
- The quantification of serum FLC is used as an aid in the diagnosis and monitoring patients with Multiple Myeloma.
- Ratio FLC value (kappa FLC/lambda FLC) compared to reference ranges may indicate presence of plasma cell disorders disease like Multiple Myeloma or AL amyloidosis in a patient.
- Nephelometric and turbidimetric based assays have been shown to overestimate the sFLC levels that are not always consistent with Serum Protein Electrophoresis/Immunofixation and other clinical parameters.
Key benefits
A trusted and cost-effective FLC solution with strong, proven performance, delivering highly reliable results essential across the entire the multiple myeloma patient journey.
Trust in the results
with concordance value between SPE and FLC Kappa & FLC Lambda which help on interpretation results.
Follow IMWG guidelines
"20" and "100" FLC ratio cut-points can be used with Sebia FLC assays, for an appropriate patient management and easier implementation in the laboratory.
4 times lower retest rates
vs other methods and lower manual dilutions needed.
Easily adapted and scalable
to any type of ELISA Instrument for standardization and efficiency process.
Clinical performance
96.8% concordance based on the IMWG Criteria for the Diagnosis of MM
Main characteristics
Test principle
Quantification of Kappa or Lambda Free Light Chains is performed with an Enzyme-Linked Immunosorbent Assay (ELISA) procedure utilizing specific antibodies anti-Kappa or anti-Lambda free light chains.
