Free light chains (FLCs) are immunoglobulin light chains that are found in the serum (blood) in an unbound (free) state. In recent decades, measuring the amount of free light chains (FLCs) in the blood has become a practical clinical test.

Since NICE Myeloma: diagnosis and management guidelines were published and updated in October 2018, the use of serum free light chains (sFLC) in the diagnosis and monitoring of myeloma and monoclonal gammopathy of undetermined significance (MGUS) …

A free light chains test is used to measure the level of free light chains in the blood and compare the amount of kappa and lambda light chains. This ratio can help diagnose or monitor how well the treatment of plasma cell disorders is working.

2022年2月2日 · A kappa free light chain test is a quick blood test that measures certain proteins in your blood. High levels of these proteins may mean you have a plasma cell disorder. A healthcare provider might order a kappa free light chain test if you …

2023年11月2日 · Background: Serum free light chain (FLC) measurement, consisting of serum free kappa, serum free lambda, and a calculated FLC ratio (kappa/lambda), plays a pivotal role in the diagnosis, risk stratification and management of plasma cell disorders.

Serum free light chain assay, Freelite (brand name) What is this test? This test looks for signs of antibodies called immunoglobulins in your blood. Immunoglobulins are made by white blood cells called plasma cells. They help protect you against infection and illness. Plasma, or myeloma, cells are found in your bone marrow.

2021年11月9日 · Serum free light chain (SFLC) testing is ordered to help detect, diagnose, and monitor plasma cell disorders (dyscrasias), including multiple myeloma, primary amyloidosis, and related diseases or to monitor the effectiveness of treatment. Light chains are proteins produced by plasma cells.

It detects low concentrations of FLCs and can measure the ratio of kappa chains to lambda chains. It has been suggested that the SFLC assay could play an adjunctive role in screening, diagnosis, monitoring, and prognosis of PCDs in high-risk populations.
