Serum Free Light-chain Assay for the Diagnosis, Management, and Prognosis of Multiple Myeloma
In recent decades, new serum biomarkers have been developed for routine laboratory practice, such as assaying serum free light chains and more recently, assaying immunoglobulin heavy and light chain isotypes (Hevylite). In this work, we highlight the interest of new biomarkers (Hevylite Test) in the management of monoclonal gammopathies because of the technical advantages it confers and the se...
متن کاملAnalytical performance of the serum free light chain assay.
BACKGROUND The Freelite system for nephelometric or turbidimetric measurement of serum free light chains (FLCs) has been available since 2001. It has been valuable for the management of patients with oligosecretory myeloma, light chain myeloma and AL amyloidosis. However, there are several limitations of the method. The goal of this study was to evaluate the analytical performance of the FLC as...
متن کاملSerum Free Light Chain Analysis
In healthy individuals, plasma cells originating from the bone marrow produce immunoglobulin molecules composed of two heavy chains and two light chains. There are two types of light chains in humans. The κ light chains are encoded by the immunoglobulin κ locus on chromosome 2 and λ light chains are encoded by the immunoglobulin λ locus on chromosome 22 [1]. During B lymphocyte development, the...
متن کاملMonoclonal vs polyclonal free light chain assays.
Am J Clin Pathol 2009;131:897-903 901 © American Society for Clinical Pathology relative to Freelite (Figure 1). Both patients had negative results for urine BJPs, further undermining the validity of the ELISA assay results. It is possible that the monoclonal antibodies are cross-reacting with the reported IgG λ and IgA λ monoclonal intact immunoglobulins in these patients, leading to falsely r...
متن کاملSerum free light chain assays not total light chain assays are the standard of care to assess Monoclonal Gammopathies.
The diagnosis of Multiple Myeloma is a challenge to the physician due to the non-specific symptoms (anemia, bone pain and recurrent infections) that are commonplace in the elderly population. However, early diagnosis is associated with less severe disease, including fewer patients presenting with acute renal injury, pathological fractures and severe anemia. Since 2006, the serum free light chai...
