Methods: Ten control and 16 test (10 MG and 6 RP) patients presenting consecutively to the
Pathology Department were selected for the study in July–August 2014. Serum total light …

Materials and Methods The primary study cohort consisted of 27 IMM (mean age: 75 yr;
range 51–90; 16 M, 11 F) and 54 MGUS (mean age: 74 yr; range: 47–99; 23 F; 31 M) …

Objectives: Serum free light chain assay is a recommended screening test for monoclonal
gammopathies. Anecdotal observations indicated a high rate of false-positive abnormal κ/λ …

Background Serum free light chain assay (SFLCA) and κ/λ ratio, and protein electrophoretic
methods are used in the diagnosis and monitoring of monoclonal gammopathies. Methods …

Objective Several laboratory and imaging assays are required to diagnose multiple
myeloma (MM). Serum and urine immunofixation electrophoresis are two key assays to …

This study evaluated serum κ and λ free light chain (FLC) concentrations in a Veterans
Affairs (VA) population. We hypothesized that our older, mostly male, population should not …

TO THE EDITOR: Serum protein electrophoresis (sPEP) and serum immunofixation
electrophoresis (sIFE) are the gold standards for diagnosing monoclonal gammopathies …

Objectives Free light chain (FLC) assays and the ratio of κ/λ are recommended for diagnosis,
prognosis and monitoring of plasma cell dyscrasias (PCD). Limited data exists on FLC …

The International Myeloma Working Group considers the serum free light chain (SFLC)
assay to be an adjunct to traditional tests. Apart from the FLC ratio, the absolute values of …

Background Serum free light chain (FLC) assays are used clinically to measure the
concentration of κ and λ FLC in patients with suspected or diagnosed plasma cell …
