Test Details
Methodology
Enzyme-linked immunosorbent assay (ELISA)
Result Turnaround Time
1 - 5 days
Turnaround time is defined as the usual number of days from the date of pickup of a specimen for testing to when the result is released to the ordering provider. In some cases, additional time should be allowed for additional confirmatory or additional reflex tests. Testing schedules may vary.
Use
Establish evidence of infection/exposure to Bordetella pertussis, the causative agent of whooping cough
Custom Additional Information
Patients with acute infection develop IgG, IgM, and IgA antibodies to fimbrial agglutinogens, and IgM and IgA antibodies are probably diagnostic. Following vaccination, IgG and IgM antibodies can be demonstrated, except in infants. IgA antibodies do not develop.
