The present invention is a method for the characterization or detection of one or more antibodies in a sample. The method comprises obtaining a tagged antigen comprising an antigen and a mass tag attached to the antigen. The tagged antigen has specificity for the antibody. In addition, the method comprises combining the tagged antigen with the antibody to form a tagged antigen-antibody complex. Further, the method comprises cleaving the mass tag from the tagged antigen-antibody complex. Thereafter, the method comprises analyzing the mass tag via a mass spectrometer to determine the presence of the mass tag in the sample and correlating the presence of the mass tag with a presence of the antibody in the sample.
