Web6 Mar 2024 · This can be measured by the Free Light Chain Assay test on a blood specimen. In general, the higher the free light chains, the more aggressive the disease is. Therefore, the serum free light chain test is a better predictor of outcome than the amount of M-protein in the blood. What are light chains? There are two types of light chains: kappa ... Web21 Dec 2024 · Rarely, the malignant plasma cells produce only free light chains, without an accompanying heavy chain–as in Kappa- or Lambda-only Myeloma. In rare scenarios, malignant cells overproduce only heavy chains. Next, Some Definitions What’s in the SPEP (Serum Protein Electrophoresis): An SPEP is a way of measuring and mapping proteins.
