Bordetella pertussis Antibodies, IgG and IgM by ELISA with Reflex to Immunoblot
If serology is used to assess late-stage pertussis, the recommended test is Bordetella pertussis Antibodies, IgA and IgG by ELISA with Reflex to Immunoblot (2001774). CDC-recommended first-line tests for pertussis are Bordetella pertussis/parapertussis by PCR (0065080) and/or Bordetella pertussis Culture (0060117).
Semi-Quantitative Enzyme-Linked Immunosorbent Assay/Qualitative Immunoblot
