The patient sample is added to the well that contains the antigen (B) bound to the plate. The presence of antibodies in the patient sample will bind to the antigen, and detection antibodies (labeled with an enzyme) will bind to those antibodies. The substrate is then added, and a color change indicates the presence of antibodies in the patient sample.
