摘要
Abstract
Objective To study the effectiveness of the laboratory diagnosis of multiple myeloma(MM)patients with immun-ofixtion electrophoresis (IFE),protein electrophoresis (SPE)and immunoglobulins and light chain quantitative analysis. Methods Selected 192 MM patients and 30 healthy controls during June 2012 to December 2013 and analyzed the results of IFE,SPE and immunoglobulins,and light chain quantitative analysis in MM patients.Results M protein bands were seen in 120 cases (62.5%)by using SPE and M protein were positive in 174 cases (90.6%)among the 192 MM patients by using IFE.IFE showed that IgG were maximum type of the M protein (106 of 192,55.2%).There were IgG-λ type 66 cases (34.4%),IgA type 36 cases (18.8%)and free light chain type 24 cases (12.5%).Immunoglobulins of different immuno-phenotypes had higher than the nomal group with serum immunoglobulin and light chain quantitative analysis (P <0.05). The detection rate was 67.7% (130/192).Whateverκ-type M protein orλ-type M protein,the ratio ofκ/λwas significantly abnormal (P <0.05).The detection rate was 85.4% (164/192).Conclusion The better detection rate of immunological techniques such as immunofixtion electrophoresis and immunoglobulins quantitative analysis might provide valuable basis for the diagnosis and treatment of MM clinically and prevent misdiagnosis.关键词
