Monoclonal gammopathies indicate a clonal expansion of plasma cells or mature B lymphocytes.Immunotyping of monoclonal proteins in the urine done by immunofixation electrophoresis (IFE) identifies the monoclonal immunoglobulin heavy-chain (gamma, alpha, mu, delta, or epsilon) and/or light-chain type (kappa or lambda). This aids in the diagnosis of monoclonal gammopathies.
