【摘要】Monoclonal gammopathies are characterized by the presence of monoclonal immunoglobulin in patients with or without evidence of multiple myeloma (MM), macroglobulinemia, amyloidosis (AL), or a related plasma cell proliferative disorder. This study aims to evaluate laboratory diagnostic characters of monoclonal gammopathies and investigates the correlation between monoclonal gammopathies and transforming growth factor β1 (TGFβ1). Immunofixation electrophoresis (IFE), serum protein electrophoresis (SPE), nephelometry and urine light chain ELISA were used for laboratory identification of monoclonal immunoglobulins. Plasma TGFβ1 was detected with double-antibodies ELISA. Lightcycler was used for single nucleotide polymorphism (SNP) analysis. Totally 2,007 cases of monoclonai immunogiobulin (M protein) were identified in 10,682 samples. The isotypes of M protein were IgG type 47.1%, IgA 23.0%, IgM 8.7%, IgD 5.3%, free light chain κ 6.1%, λ 9.8%. In reference to IFE, the coherency of diagnosis was serum light chain ratio (κ/λ) 94.4%, quantitation of lgs 83%, light chain quantitation 80.9%, and urine light chain ratio (κ/λ) 58.0%. Plasma TGFβ1 was
