A New Electrochemiluminescence-Based Multiplex Assay for the Assessment of Human Antibody Responses to Bordetella pertussis Vaccines.

Introduction: Commercially available enzyme-linked immunosorbent assay (ELISA) kits designed for pertussis diagnostic purposes are frequently used to assess antibody responses to pertussis vaccines in clinical trials, but have limited accuracy and are not calibrated against international standards. We developed a new electrochemiluminescence (ECL)-based multiplexed assay and compared its performance to two commercial Bordetella pertussis ELISA kits and to historical in-house ELISAs.

Methods: The ECL assay quantifies serum concentrations of antibodies against four B.
