Freelite®

Freelite® is a major breakthrough for the detection and monitoring of Multiple Myeloma (MM) and related disorders.

Freelite® Serum Free Light Chain Assays are:

  • Highly sensitive and specific latex-based tests that evaluate free kappa and free lambda levels through their normal serum ranges.
  • Quantitative and automated assays that measure free kappa and free lambda light chains.
  • Recommended in the NCCN Clinical Practice Guidelines in Oncology and in the International Myeloma Working Group Guidelines for use in the initial diagnostic workup of multiple myeloma and related disorders.1,2

Freelite® assays are offered by all major reference laboratories and most myeloma centers in the USA. Freelite can be run on several immunology and clinical chemistry analyzers. For more details, please scroll down.  

 Freelite® provides quantitative measurement of:

  • Free kappa
  • Free lambda
  • Free kappa / free lambda ratio

The serum free light chain ratio is a strong indicator of monoclonality and is valuable for distinguishing monoclonal from polyclonal diseases.

Freelite® can be used:

In patients with:

Freelite® Kit Components include:
