Detectable levels of IgG antibodies to B. pertussis may be seen in the serum of vaccinated individuals of all ages, in early infancy as the result of placental transfer, and in the convalescent phase of a recent infection. IgG antibodies can only be used to diagnose active infection when paired sera are available and a rise in antibody level can be demonstrated. A significant rise may not always be demonstrated as peak levels of IgG may be reached before the first sample is collected. Therefore, IgA and IgM antibody levels should be measured to diagnose active disease.
