By using a highly sensitive serum M protein detection method based on the MALDI-TOF MS platform, serum monoclonal immunoglobul (M protein) in detection was performed on the visiting patients to explore the positive rate of serum M protein and its distribution in different departments. And exploring the correlation analysis between the relative concentration of serum M protein based on the above highly sensitive methods and clinical indicators.
