Bordetella Pertussis Serology, Blood

Diagnostic Use

When considering testing for Bordetella Pertussis, PCR is the test of choice during the acute stages of pertussis infection, up to 4 weeks after the onset of symptoms.
Not used for immune status.The presence of B. pertussis IgG is not a reliable indicator for a patient’s immune status and should not be used in this context. We do not process samples for Bordetella immunity status. Where immune status is needing to be assessed, immunisation history and/or booster immunisation is recommended.

Serology is still of value for epidemiological surveillance and will from the 1st January 2020 routinely only be performed when requested by a public health team involved in outbreak management. Outside of this criteria, tests that are clinically indicated will be considered following contact and discussion with the clinical Microbiologist.
