May be used as evidence of vaccination or past infection; test does not determine immunity to B. pertussis. CDC-recommended first-line tests for pertussis are Bordetella pertussis/parapertussis by PCR (0065080) and/or Bordetella pertussis Culture (0060117). In most cases, serology testing is not recommended for the diagnosis of active pertussis infection.
