Additional information Some adult patients may develop a subacute illness characterized by a prolonged period of coughing-for a month or more-following Bordetella infection. As these patients have often been treated with antibiotics and because organisms often cannot found by PCR or culture in late stages of illness, an elevated antibody titer may be the only way to confirm the suspected diagnosis of adult pertussis. A rise in titer between paired sera, one collected within 1 week of onset of illness and another 2-3 weeks later, is most suggestive of a recent infection, but a single convalescent serum specimen will be accepted. Under some circumstances, sera can be forwarded to CDC for further evaluation.
